Evaluation of a Highly Efficient Multidrug Biochip Array Technology for a Simultaneous and High-Throughput Urine Drug Screening in Clinical and Toxicological Settings

Background: A high-throughput and highly efficient analytical platform for urine drug screening is critical in both clinical and forensic settings. Mass spectrometry (MS) has better sensitivity and specificity than conventional immunoassays (IA); however, not all laboratories have the necessary resources and workforce to operate MS. The goal of this study was to evaluate a multidrug biochip with 20 discrete testing regions (DTRs) for high-throughput urine drug screening (UDS). Methods: The Randox DOA Ultra Urine (DOAULT URN) biochip employs chemiluminescent IA to detect various analytes, including stimulants, hallucinogens, sedatives, narcotics, and dextromethorphan. The verification included the evaluation of the limits of detection (LOD), stability of calibrators and controls, cross-reactivity, carryover, interference, and overall performance. Results: LODs
