When you are looking to buy a drug test it is important to know what you are looking for (whether it is a business employee drug test or a home drug test).  You want to get the best drug test for your testing purpose.  There are many different types drug tests out on the market today.  Of all drug test types, the urine drug tests are one of the more popularly used forms of drug tests and have been around for many years.  More recently added to the various types of drug testing are the saliva drug tests which are becoming popular; mainly due to the fact that they are more sanitary and gender friendly. In addition to drug tests, there are tests that will detect the presence of alcohol in saliva or breath.  Hair drug test is one of the more accurate drug test methods, but require a laboratory for screening.  There are also sweat drug screens that like the other tests, will determine the presence of drugs or their metabolites in the human body.

For more extensive information on the different kinds of drug tests see, Different Types Of Drug Tests information below.

The most popular forms of drug testing are as follows (various forms or types of drug tests):

One of the most recent additions to the different kinds of drug tests is that of Steroids Test.  Steroid testing is a Lab Test that detects the presence of steroids in a urine sample provided.  Steroid testing is performed by taking a urine specimen and sending it off to a laboratory for confirmation. The test will detect the presence of steroids in the urine sample.  For more information on steroids, see What Is A Steroid?

Different Types Of Drug Tests

There are five primary types of drug tests: urine, blood, hair, saliva, and sweat. Most common is the urine test which has the benefit of being inexpensive and less intrusive than the blood test.

Urine drug tests are the least expensive of the test methods (from $3 for the home drug test version).  Urine tests are considered an intrusive method of drug testing.  A urine drug test can be done at home (for example by parents) though require lab verification (lab confirmation) for accurate results.  These types of tests detect use primarily within the past week (longer with regular drug use).  Urine tests can be affected by abstaining from drug use for a period of time before the test.  Urine drug test cups are often temperature tested to insure sample integrity.

Saliva drug tests are a little more expensive than urine testing, but less than hair or blood.  They range in price beginning at around $14.  Saliva tests are considered a relatively nonintrusive method of drug testing.  Saliva drug testing is becoming more common as it is easy to administer.  Like urine tests, saliva testing requires lab processing to ensure accuracy.  The saliva drug test can detect drug use primarily within the past few days (sometimes in as few as 24 hours). These tests can detect more recent use than other testing methods (in as short as one hour after drug use).  Saliva drug tests have no nationally accepted standards or cutoff concentrations for detection, making results greatly dependent on the specific product purchased. This could also make results less-reliable and/or acceptable for legal cases.  As far as accuracy goes, saliva tests are more reliable for detection of Methamphetamine and Opiates, less reliable for THC or Cannabinoids (2004).

Hair drug tests are currently several times more expensive than urine tests (start at $58) and are considered a relatively nonintrusive method of drug testing.  Hair follicle tests detect substance use over a longer period (up to 90 days, depending upon hair length), but do not usually detect use within the past week.  A hair drug test requires a sample of hair about the diameter of a pencil and 1.5 inches long.   They can not be done with a single hair.  Typically, hair tests positive a little more than twice as often as a urine test.  In a recent study, out of 1823 paired hair and urine samples, 57 urine samples tested positive for drugs of abuse; while 124 hair samples from the same group tested positive.  Unlike urine or saliva tests, hair drug tests are not significantly affected by brief periods of abstinence from drugs.  Hair tests can sometimes be used to determine when use occurred and if it has been discontinued. Drugs, such as opiates (codeine, morphine, heroin) lay down on the hair shaft very tightly and are shown not to migrate along the shaft, thus, if a long segment of hair is available one can draw some "relative" conclusions about when the use occurred. However cocaine, although very easy to detect, is able to migrate along the shaft; making it very difficult to determine when the drug was used and for how long.  Labs performing hair tests claim to be able to reliably differentiate between opiate and poppy seed use.   Some hair drug tests now check for more than the SAMHSA-5, and include at least Cannabis, Ecstasy/MDMA, Cocaine, Opiates, Methamphetamine, Amphetamine, Phencyclidine (PCP), Benzodiazepines, & Barbiturates.

Blood draw drug testing is the most expensive method of testing.  It is considered the most intrusive method of testing.  Blood drug tests are the most accurate method of testing and are the least common method of drug testing (most likely due to cost).

Sweat drug tests are considered a relatively intrusive method of drug testing because they require the wearing of a patch for an extended period of time.  The sweat patch is still relatively uncommon and are a controversial in terms of accuracy. There is some reason to believe that surface contamination (such as cannabis smoke) can cause a false reading.  The sweat drug test can detect use which would not trigger other tests. Because of the short detection period for many drugs in urine, single use of many drugs longer than a week prior to using the patch will not cause a positive urine test.  Because the skin patches are gathering sweat over an extended period of time, it is possible that any use during that time will produce a positive result.
