Doping Far More Existent Than Thought!

UsaDrugTest — Mon, 08 Feb 2010 14:31:02 +0000

Doping is one issue that has spread out its ugly fangs into almost every sport. Doping, as must be known to everybody, is much more common among the athletes. Time and again doping or the use of prohibited drugs has ruined sportsmen and thwarted all their hard earned name, fame, fortune, and respect in matter of seconds. Sportsmen like Diego Maradona, Michael Johnson are examples who ruined their flourishing careers owing to the use of prohibited drugs. There are many other sportsmen who lost their medals and honour when they were found guilty of doping. Doping is today no longer restricted to the athletes alone though it is still more common among them. In almost all the sports doping has become an issue to worry about. Not surprising therefore that today almost in every major sport event vigorous doping tests are conducted.

Doping and use of the prohibited drugs is far more widespread than we know. There are drugs that are used by sportsmen and that are not detectable. Whether or not these drugs are harmful to the human body is a different matter but they are definitely not to be used by sportsmen. Among the athletes use of prohibited drugs is almost imperative. According to insiders almost all the athletes use drugs. Interestingly these athletes are even encouraged by their coaches to use these drugs. Use of drugs is an open secret in the world of athletics. There is nothing to hide or controversial about the use of these drugs. It’s known to everyone that these performance enhancing drugs are widespread in the athletic circuit. The only thing is that they are discreet about it.

The life of an athlete is not easy. An athlete remains at the top for maximum three to four years. The popularity and money earned in this period proves to be instrumental for the athlete. The rest of his life depends on what he earns in his years on the top. Thus if some drug helps him to capture that top slot, the athletes go for it. Contrary to what people believe, doping doesn’t help sportsmen perform better directly. They help them to recover quickly and get less tired. This in turn helps the athletes to train harder thus enhancing their skills and fine tuning them.

The drugs that are used in the sports arena are prescribed. The doctors who prescribe these drugs are also helpless in deterring the athletes from using them. So what they do is that they instruct them on how to use the drugs so that they are not adversely affected by the side effects of the drugs. It is not unnatural that the drugs that are beneficial also have side-effects. As for example quit smoking drug chantix. One of the most popular drugs in this category, people trust chantix the most which is evident from the huge number of people who opt buy chantix to help them come over the nicotine withdrawal symptoms. If you are a smoker and want to quit, you can buy chantix online. It is convenient and easier to track chantix online. On a lighter note you won’t be penalized for having the quit smoking drug as is the case with doping!

Is There Any Nicotine In Your Blood?

UsaDrugTest — Sun, 07 Feb 2010 15:14:21 +0000

When you inhale nicotine, it enters your blood stream and your body metabolizes it into continine. Therefore, checking for continine is a way to determine if you are a smoker. Nicotine tests apply immunoassay technology to detect continine in blood, hair, urine, and saliva. All nicotine tests detect the presence of continine at a cut-off point of 200 ng/ml.

How accurate is this kind of test? A member of alt.smokers discussion group say the tests achieves 95 percent accuracy. The tests can measure the level of continine in the body for as long as two weeks.

How long does it take for nicotine to surface in urine tests? American Lung Cancer states that nicotine is gone from your blood and urine within 72 hours after your last cigarette. what you can still find in your urine though, is continine.

Nicotine tests are taken for a few reasons. The most obvious reason is for health insurance. Insurance companies conduct nicotine tests to classify smokers into three different premium classes. As a smoker, your premium will be higher than a non smoker. Studies show that smokers pay as high as three times the premium of non smokers. If you remain smoke free for five years, you get to enjoy the lowest premium.

Another reason would be for concerned parents who want to know whether their teenage child smokes or not. With nicotine tests, you can check your child’s tobacco consumption. If you have a family member who smokes in the home, you can examine the exposure of second hand smoke using this test.

American surveys reveal that more than 4 million children under 18 smoke cigarettes. Newspaper headlines expose teenagers smoking in schools. It is no surprise then that some high schools screen their students for cigarettes. School administrators believe that tobacco consumption can lead the students to drug abuse.

When you undergo a smoking cessation program, you can use a continine test kit to confirm your freedom from nicotine and the effectiveness of the program itself. You will also find it useful if one of your quitting methods involves nicotine cleansing products. You can know if it really removes nicotine from your body.

You can easily purchase nicotine test kits from pharmacies, drug stores, or over the internet. The more common brands include NicAlert, TobacAlert, and COT.

Some say that nicotine can leave your body within 24 hours. So, why do you need nicotine tests then? A study by Exam & Profile Services in Wisconsin indicates that continine will appear in urine for weeks after smoking. Unlike other conventional methods such as gas chromatography and HPLC-mass spectrometry, you can use nicotine test kits at home. They are also cheap and simple to apply.

Important Factors That Influence Results of Blood Tests

UsaDrugTest — Thu, 04 Feb 2010 00:16:04 +0000

Each blood collection situation is unique. A competent phlebotomist must not only possess the technical skills necessary to collect a quality specimen, but must also understand the numerous patient variables, complications, and procedural errors that can affect the integrity of the specimen or the health and safety of the patient to avoid or reduce any negative impact.

Factors Include:

Age

Some physiologic functions such as kidney function decrease with age in adults. For example, creatinine clearance, a kidney function test, is directly related to the age of the patient, which must be used in calculating test results.

Diet

Some laboratory tests are affected by ingestion of certain foods, which must be eliminated from the diet for several days before the test specimen is collected. For example, some methods that detect occult (hidden) blood in stool specimens also detect similar substances in meat and certain vegetables. Therefore a special diet that eliminates these foods must be followed for several days before the specimen is collected.

Fluid intake can also affect blood composition. Excessive fluid intake may cause decreased Hgb levels and alter electrolyte balance. Consumption of caffeine has been demonstrated to affect cortisol levels. Recent alcohol ingestion may also affect test values, especially glucose values.

Altitude

Decreased oxygen content of the air at higher altitudes causes the body to produce more RBC’s to fulfill the body’s oxygen requirements; the higher the altitude, the I greater the increase. Thus RBC counts and related determinations such as hemoglobin (Hgb) and hematocrit (Hct) will have higher normal ranges at higher elevations.

Daily Variations

Many blood constituents exhibit daily variations or normal fluctuations throughout the day. Factors that play a role in daily variations include activity, eating, daylight and darkness, and being awake or asleep. White blood counts, eosinophil counts, and iron levels are lower in the morning than in the afternoon. Cortisol, insulin, potassium, and testosterone levels are highest in the morning. Daily variations can be large. For example, cortisol levels and iron levels can differ by 50% or more between 8 AM and 4 PM.

Dehydration

Dehydration (a decrease in total body fluid) that occurs with persistent vomiting or diarrhea, for example, causes hemconcentration, a condition in which blood components that cannot easily leave the blood stream become concentrated as a result of the smaller plasma volume. Hemconcentration falsely increases some blood components such as RBCs, enzymes, iron, calcium, and sodium. In addition, it is often difficult to obtain a blood specimen from a dehydrated patient.

Fever

Fever affects the levels of a number of hormones. Hypoglycemia caused by fever increases insulin levels followed by a rise in glucagon levels. Fever also increases cortisol levels and may disrupt its normal diurnal variation.

Drug Therapy

Many drugs alter physiologic functions. In most instances, the effect is desired. In some individuals, however, there are unwanted physiologic effects called side effects or sensitivities. For’ example, thiazide diuretics often cause increased calcium levels and may cause low potassium levels. Chemotherapy drugs often cause a decrease in the cells of the blood, especially WBCs and platelets. Numerous drugs are toxic to the liver, causing an increase in liver enzymes such as serum glutamic-oxaloacetic transaminase (aspartate transaminase), alkaline phosphatase, and lactate dehydrogenase- (LDH/LD). Steroids and diuretics can cause pancre’atitis and an increase in serum amylase and lipase values.

Drugs may also interfere with the performance of the test in the laboratory, causing false increases or decreases in test results. Many lab test procedures are based on fluorescent, chromogenic (color-producing), peroxide-generating, or reagent-binding reactions. A drug may compete with the test reagents for the substance being tested causing a false-negative or false low result, or the drug may enhance the reaction, causing a false-positive or false high result. An acronym used for substances that interfere with the testing process is CRUD, which stands for “compounds reacting unfortunately as desired.” The College of American Pathologists (CAP) has developed guidelines for reducing interference from drugs that are known to interfere with testing procedures.

Drugs known to interfere with urine testing should be avoided for 48 to 72 hours before urine sample collection. It is up to the physician to recognize or eliminate drug interferences; however, it is helpful to the technician or technologist performing the test in the laboratory if the phlebotomist notes on the lab slip when he or she observes medication being administered just before blood collection.

Smoking

Nicotine affects a number of blood components. The extent of the effect depends upon the number of cigarettes smoked. Patients who smoke before specimen collection may have increased cortisol levels and white blood counts. Chronic smoking often leads to decreased pulmonary function and increased hemoglobin levels.

Exercise

The effect of exercise on blood composition depends upon the duration and intensity of the activity and the physical condition of the patient. However, even moderate muscular activity will elevate levels of a number of blood components, such as lactic acid, creatinine, protein, and certain enzymes. Levels of these substances return to normal soon after the activity is stopped, with the exception of enzymes such as creatine kinase and LDH, which may remain elevated 24 hours or more.

Gender

A patient’s gender or sex has a determining effect on the concentration of numerous blood components. Most differences are apparent only after sexual maturity. Differences are reflected in separate normal values for male and female patients. For example, RBC, Hgb, and Hct normal values are higher for males than females.

Pregnancy

Pregnancy causes physiologic changes in many body systems. Consequently, results of a number of laboratory tests must be compared to normal ranges established for pregnant populations. For example, body fluid increases, which are normal during pregnancy, have a diluting effect on the red blood cells, leading to lower red blood counts.

Stress

Emotional stress in the form of fear or anxiety has been shown to cause short-lived elevations in WBC counts, decreases in serum iron, and increases in adrenal hormone values. For example, studies on crying infants demonstrated marked increases in WBC counts. Counts returned to normal within 1 hour after crying stopped. For this reason, it is best if complete blood count (CBC) or WBC specimens are obtained after the infant has been sleeping or resting quietly for at least 30 minutes. If a specimen is collected while an infant is crying, it should be noted on the report.

The field of psychoneuroimmunology (PNI) deals with the study of interactions between the rain, the endocrine system, and the immune system. PNI studies have demonstrated that receptors on the cell membrane of WBC’s can sense stress in a person and react by stimulating an increase in cell numbers.

Position

A patient’s body position both before and during venipuncture influences blood composition. Going from a supine (lying down on the back) position to standing causes the water or plasma portion of the blood to filter into the tissues, resulting in a decrease in plasma volume and an increase in nonfilterable elements, or substances such as proteins, iron, calcium, and blood cells, that cannot easily pass through the walls of the blood vessels. For example, the RBC count on a patient who has been standing for approximately 15 minutes will be higher than the basal state RBC on the same patient.

Basel State

The ideal time to collect blood from a patient is when the patient is in a basal state. Basal state is the condition of the body when a patient has refrained from strenuous exercise and has not ingested food or beverage except water for 12 hours (fasting). Collecting a basal state specimen minimizes or eliminates the effects of diet, exercise, and other controllable factors on test results and also provides the ideal specimen for establishing reference ranges or normal values for laboratory tests on inpatients.

Alzheimer’s Disease – a Surprising Way to Prevent & Provide Relief to Sufferers

UsaDrugTest — Mon, 01 Feb 2010 10:12:07 +0000

There is a natural compound that is cheap, common and could provide significant heath benefits for a number of diseases including Alzheimer’s disease and a number of other diseases of the brain. So what is this compound?

Surprisingly it’s nicotine. Although Nicotine has suffered from an image problem due to its association with smoking, the fact is nicotine in its pure form is safe and non toxic and is part of the natural food chain.

Nicotine is in fact found in many common foods such as chili peppers, cauliflower tomatoes and potatoes, as well as many teas.

Nicotine has a bad reputation due to its link with cigarette smoking, but the fact is it is some of the other 4,000 chemicals that are consumed in smoking that are the killers not nicotine.

Today, many companies are conducting research into nicotine and its affect on the brain. It has been known for a long time that it improves concentration, attention and has a beneficial affect on mood.

It is this affect on the brain that has led scientists to look at Nicotine’s potential in diseases including Alzheimer’s disease.

Alzheimer’s disease Prevention

Alzheimer’s disease occurs when the degeneration of various structures in the brain occurs, with the development of amyloid plaques and neuro-fibrillary tangles then deficiencies of acetylcholine and other neurotransmitters also can occur.

New research indicates that nornicotine, produced when nicotine is absorbed into the body, prevents the formation of protein lumps, or plaques, in the brain area that are associated with Alzheimer’s disease.

Alzheimer’s disease alleviating the symptoms

Scientists are also looking at nicotine to treat Alzheimer’s disease when it has already occurred. Tests have already been carried out to repair damaged memory ability in rats.

Nicotine is thought to help alleviate the effects of Alzheimer’s by attaching to receptors of the brain acetylcholine, a chemical important in learning and memory, of which a loss of is common in Alzheimer’s disease.

While medical research is still inconclusive in many areas, it does appear that Nicotine has potential to help with a number of diseases that include brain function.

In addition to Alzheimer’s disease, medical research is being undertaken into Nicotine’s affect on suffers of:

Depression, Parkinson’s disease, attention disorders and Schizophrenia.

Many drug companies are researching the possibility of treatments that include nicotine to combat the above diseases and alleviate the symptoms.

Nicotine needs to be delivered in its pure form and companies have already looked at and launched nicotine in water which is a safe delivery method and other products look set to follow.

After being treated with suspicion for many years due to its association with smoking nicotine is being seen in a different light.

In its natural form it is safe and non toxic and not only does not cause disease, it may actually have huge potential as a medical treatment.

As research intensifies expect to here more news on nicotine in relation to a number of diseases including Alzheimer’s. It maybe that in the near future nicotine could be seen in a completely different light and not simply associated with smoking.

Selection Criteria for Egg Donors

UsaDrugTest — Sun, 31 Jan 2010 00:39:49 +0000

To become an egg donor, women must meet certain requirements. The standards for donating eggs are set by the American Society of Reproductive Medicine (ASRM). Clinics and agencies that deal with egg donation services must follow their standards to become licensed and most reputable physicians and fertility clinics follow their guidelines. The FDA may also have certain guidelines.

Donors must be between 21 and 34 years old and be in good health to be an egg donor. The donor should have a clean medical history and family medical history. This means that no genetic disorders or diseases may be present. Donors are also required to lead a healthy lifestyle meaning they should not drink heavily, smoke, take drugs or take part in any unhealthy activities or lifestyles.

Egg donors are required to go through a series of tests to detect any nicotine, drug or alcohol use, infectious diseases, genetic mutations or other conditions. The donor may also be screened to ensure that she is able to produce an appropriate amount of eggs in each cycle. The fertility clinic or egg donation agency may have their own standards in addition to those set forth by the FDA and ASRM. A donor may be limited by the ASRM to donating no more than six times in her lifetime.

A donor will be paid for her time, travel and effort. Typically, this means being paid between $5,000 and $10,000, but each clinic or agency may vary. Women who are interested in becoming egg donors should speak with a medical professional or representative at a reputable fertility clinic or egg donation agency for more information. Donors should discuss the procedure and any fertility drugs they may be required to take with a medical professional at one of these facilities so that they fully understand all that is involved.

Military Drug Testing

UsaDrugTest — Sat, 30 Jan 2010 23:14:50 +0000

Drug testing in the armed forces in all types of the wings (Army, Navy and Airforce) is a must for each and every personal as the military has a zero-tolerance policy for illegal drug use. The military services conduct several types of no-notice urinalysis drug testing. Positive results on most of these tests can be used for court-martial and discharge procedures.

Department of Defense, which is more popular as DoD is attacking the problem on the two fronts of supply and demand. Education and deterrence are the key aspects of reducing demand for illegal drugs in the defense forces.

Military Drug Tests:

To combat the rising health concern of drug abuse in the defense forces, DoD uses more sensitive tests to detect ecstasy during routine urine testing. Active duty service members must undergo a urine drug test annually. Reserve component members must be tested at least every two years. DoD labs test more than 60,000 urine samples each month, but it would be next to impossible for a mistaken positive result to affect a service member’s career.

The Drug Testing Procedure:

There are several protections built-in to the system to ensure accurate results. There is always a written record of who those individuals who access the sample. People who come in contact with each sample and what exactly they do to the sample are written on the document.

After arrival at the lab, samples undergo an initial immunoassay screening (using the Olympus AU-800 Automated Chemistry Analyzer). Those that test positive for the presence of drugs at this point undergo the same screen once again. Finally, those that come up positive during the second screening test are put through a much more specific gas chromatography/mass spectrometry test. This test can identify specific substances within the urine samples.

Even if a particular drug is detected, if the level is below a certain threshold, the test result is reported back to the commander as negative. DoD labs are equipped to test for marijuana, cocaine, amphetamines, LSD, opiates (including morphine and heroin), barbiturates and PCP. But not all samples are tested for all of these drugs. Every sample gets tested for marijuana, cocaine and amphetamines, including ecstasy.

Tests for other drugs are done at random on different schedules for each lab. Some laboratories do test every sample for every drug. Commanders can request samples be tested for steroids. In this case, the samples are sent to the Olympic testing laboratory at the University of California at Los Angeles.

Comparison Of Urine And Saliva Drug Tests

UsaDrugTest — Sat, 30 Jan 2010 21:50:11 +0000

The major difference between different types of drug tests is the collection of specimen. But the advantages and disadvantages of these distinct drug tests vary in terms of many issues like invasiveness in specimen collection, risk of tampering the specimen, cost of drug test, time taken to produce results, accuracy of the results, etc. Of all the drug tests, Urine and Saliva drug tests are very common because of their efficiency to provide accurate results.

Features of urine and saliva drug testing

Both the urine drug testing and the saliva drug testing have their own advantages as well as some disadvantages.

Collection of specimen:

The major advantage of saliva drug testing over urine drug testing is its least invasiveness of privacy while collecting specimen. This has been a controversy since a long time in all the places of drug testing. The process of collecting saliva for a drug test is obviously less invasive compared to the case of urine drug test.

Chances of adulteration:

The chances of adulteration in saliva drug test are very less, compared to urine drug test. In case of saliva drug test, it is feasible to collect the specimen under legible supervision. Thus, minimizing the chances of tampering the specimen. This is not possible in case of urine drug testing. However, saliva drug test is not completely free from adulteration.

Detection period of drug abuse:

The detection period of drug abuse through saliva drug test is shorter, compared to urine drug test. The detection period in case of saliva drug test is around 20 hours to 1 day approximately, whereas it is around 3 days in case of urine drug test.

Accuracy of results:

The accuracy rate of both, urine and saliva drug tests are deemed by the United States court system. However, the accuracy rate of urine drug test results is much higher than that of saliva drug test results, the risk of false negatives is high in both the drug tests.

Cost of drug test

Cost-effectiveness is the major advantage of urine drug tests compared to any type of drug tests. The cost of saliva drug test is a little higher, compared to urine drug test. However, the cost of saliva drug testing complies with the quality of the drug test.

As both saliva drug test and urine drug test, have their own advantages and disadvantages it is not feasible to use any one of them in all the situations. Based on the comparison of features mentioned above, it will be easier to analyze and choose a drug test according to the situation.

Know How Nicotine Test Is Conducted

UsaDrugTest — Tue, 26 Jan 2010 07:59:34 +0000

Nicotine test gives the levels of nicotine addiction or abuse in a person. The drug Nicotine is one of the regularly abused and commercially available drugs in the society. Apart from tobacco smoking, nicotine is also available in forms of nicotine gum, transdermal patches, and nasal sprays. Nicotine abuse results in increased risk of lung cancer, heart diseases, COPD, strokes, asthma, blood clot formation, etc. Nicotine test will help a person in checking his nicotine abuse effectively and thus decrease its adverse affects.

Specimen Collection

Nicotine test identifies its metabolite – cotinine. Though cotinine can be measured in saliva and hair, detecting cotinine through analytical urine test is mostly prevalent and easy. It is also effective in terms of providing results as cotinine can be detected for up to 3 days after consumption at a cut-off level of 200 ng/ml.

Nicotine Drug Test Method

The One Stop Cotinine test device is an effective way of qualitative cotinine detection in human urine. It is important to make sure that the test device is at room temperature, before testing. The device must be placed on a clean and level surface. The specimen should be taken into the provided dropper. Holding the drop vertically, 3 full drops must be transferred into the S (specimen) part of the test kit. There should be no trapping of air bubbles in the S part of the kit.

Interpretation of the Results

The interpretation of the results must be read exactly after five minutes after providing sample to the testing kit. There are two ends in the testing kit labeled C (control line region) and T (test line region), where colored lines will appear. When the colored lines appear at both the regions, it indicates that the cotinine concentration is below cut-off level i.e., negative. Even a faint shade of line in T region can be considered negative. When there is no colored line in T region, but it is visible in C region of the test kit, it can be considered as positive for cotinine abuse. When a line does not appear in the C region, then the test is invalid. Invalid results are likely to show up in cases of insufficient specimen volume or Incorrect testing procedure.

Nicotine tests are helpful in many cases like smoking cessation programs, during application of life or health insurance, employee drug testing programs, for self-testing, and during medical complications.

Is it Safe to Use Chantix?-Quit Smoking with this new Drug may be Risky

UsaDrugTest — Mon, 25 Jan 2010 20:49:09 +0000

Are you thinking about quitting smoking using Chantix? Quit smoking with this new pill? Chantix is one of the newest quit smoking drugs available but is Chantix safe? It seems everywhere you look these days you see an advertisement for Chantix. Every time you turn on the television there is another commercial for Chantix. The one thing I cannot help but notice when I see these commercials is the numerous side effects of Chantix that they list.

I have friends and loved ones who want to quit smoking and are considering using Chantix to help. I decided to do a little research into this new smoking cessation drug to learn more about its side effects. So I hit the web and searched for information about Chantix. What I discovered was quite alarming.

To start off I went right to the Chantix official website to see what it had to say about the side effects of this drug, I learned that Chantix is a non-nicotine drug that works by targeting the nicotine receptors in the brain, attaches to them, and keeps nicotine from reaching them. The list of side potential side effects is amazingly long.

The most common side effect is nausea which happens in 30% of people who take Chantix. There are also other physical side effects including sleep problems, constipation, gas, and vomiting. There is even the possibility for serious skin reactions, some of which can be life threatening.

What I found even scarier was the mental and emotional side effects. These include anxiety, panic, anger, hallucinations, paranoia, and even suicidal thoughts. It was incredible to me that a drug to quit smoking had so many frightening side effects.

Chantix has a success rate of 44%. I wonder if less than a 50-50 chance of quitting smoking is worth taking a chance of experiencing some of these side effects when there are other stop smoking methods available. If, like me, you are wondering; is Chantix safe, you may want to try a different stop smoking method before you risk the side effects of Chantix.

In my research I also learned about a better alternative to Chantix. Quit smoking methods like NLP are all natural with no side effects. NLP also has a much higher success rate; 97.2% in a recently conducted test. Programs like the Quit Smoking Today program have created specially formatted NLP recordings that make cravings to smoke disappear just by listening to them.

Drug Testing at Home

UsaDrugTest — Mon, 25 Jan 2010 02:23:52 +0000

Drug Testing is usually planned to check for substances that could either provide an unfair advantage over those who do not use them or contribute to problems in the individual’s life, including impaired performance. Some people would like to remain anonymous, so they were hesitant to go for drug tests to any laboratory or consultant. They use some home drug testing kits. Drug testing at home makes it personal and private. Home Drug Testing is helpful for those who hesitate to take these drug tests explicitly and also for parents to identify drug abuse in their children.

Advantages:

The benefits of in home testing are:

· Timely- Instant testing and confirmation eliminates delays up to 3 to 4 days in waiting for laboratory results.

· Cost Effective – Small fraction of full laboratory testing fee. Initial qualitative screening results for positive drug or drug metabolite confirmations provided for in cost effective manner.

· Rapid Confirmation- Decreased stress caused by waiting for results.

· Ease of Use – Simple test procedure using subject’s urine. Compact self-contained test, no peripherals and special equipment or training necessary.

· Accuracy up to 99%- Built in quality controls and variances provide the most accurate results for a one-step test possible. Minimizes false positives through user error.

· Visual Display- Easy to read results eliminate misreading or need for examiner interpretation.

Applications :

· Random Drug Screening of Employees.

· Pre-employment screening.

· Job Applicants making sure to “Test clean”.

· Halfway House and Drug Recovery Programs.

· School and Business “Drug Free” Programs.

· School Athletic Programs.

· Zero Tolerance Home Testing Programs.

· Vehicle and Equipment operation.

· Insurance Exams.

· Routine Medical Exams and Patient Programs.

· Law Enforcement.

Saliva drug test, hair drug test urine drug test and sweat drug test- each type of drug test has unique advantages. A saliva drug test offers the advantage of a convenient collection procedure that can be directly observed by test administrator. A hair drug test extends the window of detection to three months, giving the longest look-back period of any other drug test method. A drug test that uses urine offers the advantage of solid scientific support for the test method. And because of the short window of detection for marijuana in a saliva drug test kit, positive saliva drug test results for marijuana indicate current intoxication from that drug. The sweat patch drug test system makes it very difficult for clients to substitute or adulterate the test, and offers continuous monitoring of drug use for the one week that the client typically wears the patch.
