The Triage Panel for Drugs of Abuse (DOA) was evaluated for detection of phencyclidine (PCP), amphetamines (AMPH), opiates (OPI), tetrahydrocannabinol (THC), the cocaine metabolite benzoylecgonine (BE), and barbiturates (BARB) in urine. This assay was compared with Syva EMIT. The comparisons were conducted on 606 positive and 325 negative samples. ⋯ For BARB, three samples that were negative for Triage DOA and positive for EMIT contained barbiturates levels greater than 300 ng/mL. Two of these three samples contained phenobarbital below the concentration that produces a positive result for Triage DOA. For the majority of the urine samples studied, however, the Triage DOA produced identical results to a commercial-instrument-based immunoassay.
