Types of Urine Drug Testing Explained
URINALYSIS DRUG TESTING:
Urine is the specimen of choice since it contains the most metabolites of a drug taken. Urine samples are taken from an individual and delivered to the testing lab in a specimen cup.
IMMUNOASSAY DRUG TESTING:
EMIT (Enzyme Multiplied Immunoassay Technique) - the most commonly used test for pre-employment drug screenings despite having a 4-34% "false positive" rate. RIA (Radioimmunoassay) - primarily used in the military, this test is highly sensitive. TRIAGE - this widely used test has shown to produce over 50% "false positives" results on drug-free urine.
CHROMATOGRAPHY DRUG TESTING:
TLC (Thin Layer Chromotographer) - not widely used for drug tests since results are not very reliable. GC/MS (Gas Chromotographer/Mass Spectrometer) - the most sophisticated test (over 99.8% accurate) and the most expensive type of testing, used to confirm initial results if they are positive.
