Drug test. For other uses, see Drug testing (disambiguation). A drug test is a technical analysis of a biological specimen, for example urine, hair, blood, breath, sweat, or oral fluid/salivaâto determine the presence or absence of specified parent drugs or their metabolites.
If the urine sample passes the validity tests, it gets tested for the presence of drugs. Most screening tests use a method similar to a pregnancy test, where a test strip is dipped in the urine; a positive test will cause a different pattern of lines to appear. The drug confirmation test.
