Drug of Abuse Screen, DAU10, Urine
Clinical Information: This test uses immunologic testing for drugs of abuse, by class, and screens for
the presence of amphetamines, barbiturates, benzodiazepines, cocaine metabolite, methadone, opiates,
phencyclidine, propoxyphene, tetrahydrocannabinol, and ethanol. Positive immunologic results are
confirmed by gas chromatography-mass spectrometry (GC-MS) or liquid chromatography-tandem mass
spectrometry (LC-MS/MS) with the exception of ethanol. Positive ethanol results are reported
quantitatively directly from immunologic testing.
Useful For: Detecting drug abuse involving amphetamines, barbiturates, benzodiazepines, cocaine,
methadone, opiates, phencyclidine, propoxyphene, tetrahydrocannabinol, and ethanol 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.
Reference Values:
Negative
