How could you give definition of drug test? Do you know exact meaning of drug test? A drug test is a completely technical examination of biological specimen like hair, saliva, sweat, blood, urine etc to check the presence of particular drug that is mainly parent drug or its metabolites. Main use of drug testing is at workplace, sports events, schools, universities etc. It is conducted against the prohibited drugs by laws. It includes drugs which are known by the class 5 drugs.

Positive or negative drug result is depending on so many factors. It includes potency of the drug, drug class, drug metabolic rate, person’s age, history of smoking, overall heath condition etc. For better effectiveness in the use, these metabolites have specific detection period which are integrated with their parent drug. Like if you take example of cocaine, you will get its traces only after few hours. However, there metabolites traces are available for several days.

Urine drug screening is most accepted form of the drug testing. It is simple to conduct, cheap and relatively accurate.

If screening result returns with positive value then another aliquot is send for confirmatory testing. Confirmatory testing is carried out through (GC-MS) methodology.
