Drug Tests
Drug tests is used to describe a
category of test devices and methods for detecting drugs of abuse, marijuana
(THC), cocaine (benzoylecgonin), amphetamine (AMP), methamphetamine (MET),
phencyclidine (PCP), opiates (OPI), buprenorphine (BUP), ketamine (KTM), and some other controlled substances.
Drug Test methods include
immunoassay methods, TLC, GC/MS or LC/MS analysis methods. Drug tests based on immunoassay methods
are usually for pre-screening test of drug use and GC/MS or LC/MS methods are usually for
confirmation test of urine specimens showed positive results in screening test. |

Due to its high sensitivity, GC/MS or LC/MS
analysis methods are also used for testing hair, sweat, and other specimens that
contain smaller amount of drugs of abuse.
Immunoassay drug test methods include
laboratory testing methods and rapid on-site testing methods, or point of
collection (POC) test methods. Laboratory drug testing usually employ enzyme
immunoassay, such as ELISA, or EMIT assay methods. Such methods use an enzyme
labeled drug antibody to trace small amount of drugs in urine, blood, or saliva
specimens. The enzyme can be detected by a color reaction when an enzyme
substrate is added to the enzyme containing solution. Enzyme immunoassay (EIA)
methods are usually sensitive to less than 1ng/ml concentrations, but the assay
reaction requires precision transfer of reagents, incubation time, and
instrument reading of assay results.
Rapid
test method for drug
testing is a immunochromatographic assay method or lateral flow immunoassay
method. Rapid lateral flow drug tests are simple to perform, the test reagents
are easy to transport and store. Rapid drug test methods usually involve adding
test sample one step action. Therefore, such tests are often called one-step
tests or one step tests. The test results are visually read in 5-10 minutes.
Urine drug testing devices are
the most popular among all rapid drug test devices. Urine rapid drug test
devices are made into dipsticks,
cards,
cassettes, or
cups.
