Device Story

Ready-to-use, liquid reagent, homogeneous enzyme immunoassay; detects barbiturates, methadone, benzodiazepines, and propoxyphene in human urine. Principle: competition between drug-labeled G6PDH enzyme and free drug in sample for fixed antibody; absence of free drug allows antibody binding to labeled enzyme, decreasing activity. Enzyme activity measured spectrophotometrically at 340 nm via conversion of NAD to NADH; drug concentration proportional to enzyme activity. Used in clinical laboratories; operated by trained technicians/professionals. Provides preliminary qualitative screening results; positive samples require confirmatory testing (GC/MS). Assists healthcare providers in identifying potential drug use for clinical decision-making.

LZI's Simultaneous Barbiturate-Methadone-Benzodiazepine-Propoxyphene Multiple Analyte Enzyme Immunoassay is similar to their predicates in terms of intended use, method principle, device components, and clinical performance. ### Device Description LZI's Simultaneous Barbiturate-Methadone-Benzodiazepine-Propoxyphene Multiple Analyte Enzyme Immunoassay is a ready-to-use, liquid reagent, homogeneous enzyme immunoassay. The assay uses specific antibodies that can detect barbiturates, methadone, benzodiazepines, and propoxyphene drugs in human urine with minimal cross-reactivity to various, common prescription drugs and abused drugs. The assay is based on competition between drug labeled with glucose-6-phosphate dehydrogenase (G6PDH) enzyme and free drug from the urine sample for a fixed amount of specific antibody. In the absence of free drug from the urine sample the specific antibody binds to the drug labeled G6PDH enzymc causing a decrease in enzyme activity. It is therefore the drug concentration is proportional to the enzyme activity. The G6PDH enzyme activity is determined spectrophotometrically at 340 nm by measuring its ability to convert nicotinamide adenine dinucleotide (NAD) to NADH. ### Intended Use The Simultaneous Barbiturate-Methadone-Benzodiazepine-Propoxyphene Multiple Analyte Enzyme Immunoassay is a homogeneous enzyme immunoassay, with 200 ng/mL cutoff for secobarbital, 300 ng/mL cutoff for methadone, 200 ng/mL cutoff for oxazepam, and 300 ng/mL cutoff for propoxyphene. The assay is solely intended for use in the qualitative screening human urine samples for the presence of barbiturates, methadone, benzodiazepine, and propoxyphene drugs. {2}------------------------------------------------ ### Comparison to Predicate Device LZI's Simultaneous Barbiturate-Methadone-Benzodiazepine-Propoxyphene Multiple Analyte Enzyme Immunoassay is substantially equivalent to the individual single analyte assay products in commercially distribution intended for similar use.

The assay is solely intended for the qualitative screening of human writer for these analytes. Measurements obtained by this device are used in the diagnosis and treatment of in divisiouals who have used barbiturates, methadone, benzodiazepines, and propoxyphene druation on mourvis designed for professional use with a number of automated clinical chemistry arralyzes. The Simultaneous Barbiturate-Methadone-Benzodiazepine-Propoxyphene Multiple Analyte Enzyme Immunoassay provides only a preliminary analytical test result. The assay will not identify which drug is present in the positive urine sample. All screening positive samples shall subject to minist assays to identify the drug in the sample before alternative confirmation. Gas chromations withings spectrometry (GC/MS) is the preferred confirmatory method. Clinical consideration and professional judgment should be applied to any drug-of-abuse test result, when preliminary positive results are used.
