Evaluation of the Abuscreen Online Assay for Amphetamines on the Hitachi 737: Comparison with EMIT and GC/MS Methods

CODEN: JFSCAS

Abstract

The performance of the ONLINE Assay for Amphetamines on the Hitachi 737 was compared to the Syva Emit d.a.u. Assay and GC/MS. Randomly screened (n = 2964) patient urine samples were assayed using ONLINE and Emit d.a.u. assays concurrently, using d-amphetamine, 1000 ng/mL and d-methamphetamine, 1000 ng/mL as the screening cutoff for ONLINE and Emit d.a.u. assays, respectively. All presumptive positives were confirmed by GC/MS. The specificity was 99% (2937/2964) for ONLINE and 97% (2873/2964) for Emit. Agreement with GC/MS was 80% (110/137) for ONLINE and 55% (110/201) for Emit.
