Beckman Coulter Diagnostics, Brea, Calif, has added 6-acetylmorphine (6-AM) and buprenorphine (BUP) assays to its menu of drugs-of-abuse tests. The Syva Emit II Plus 6-AM assay provides a quick way to screen for heroin usage, in place of time-consuming alternative methods such as gas chromatography–mass spectrometry (GC-MS). The assay minimizes false positives by demonstrating no crossreactivity to common analgesics, morphine, and morphine metabolites. The Syva Emit II Plus BUP assay is intended for use in laboratories for the qualitative and semiquantitative analysis of BUP in human urine. The assay also minimizes false positives due to its high specificity for BUP and norbuprenorphine, with no crossreactivity to commonly abused opiates. With a low cutoff of 5 ng/mL, the BUP assay performs with improved sensitivity to minimize false-negative results. Both the 6-AM and BUP assays deliver greater than 99% agreement with the reference method (GC-MS) and enable accurate interpretation of results.
