Clinical Information: This test uses immunologic testing for drugs of abuse by class, and screens
for the presence of amphetamines, barbiturates, benzodiazepines, cocaine metabolites, opiates,
phencyclidine, and tetrahydrocannabinol in urine. Positive immunologic results are confirmed by gas
chromatography-mass spectrometry (GC-MS) or liquid chromatography-tandem mass spectrometry
(LC-MS/MS).
Useful For: Detecting drug abuse involving: amphetamines, barbiturates, benzodiazepines, cocaine,
opiates, phencyclidine, and tetrahydrocannabinol This test is intended to be used only by a qualified
drug treatment counselor or physician.
Interpretation: A positive result indicates that the patient has used the drugs detected in the recent
past. For information about drug testing, including estimated detection times, see Drugs of Abuse
Testing at http://www.mayomedicallaboratories.com/articles/drug-book/index.html Creatinine and
specific gravity are measured as indicators of specimen dilution.
