The Roche ONLINE DAT Propoxyphene Plus assay is an in vitro diagnostic test for the qualitative and semi-quantitative detection of propoxyphene and its metabolites in human urine on automated clinical chemistry analyzers at a cutoff of 300 ng/ml. Semi-quantitative test results may be obtained that permit laboratories to assess assay performance as part of a quality control program. The ONLINE DAT Propoxyphene Plus assay is based on the kinetic interaction of microparticles in a solution (KIMS technology). Assay measurement is based on measurable changes in light transmission related to the interaction of microparticles in a solution and the sample drug of interest, if present. Propoxyphene drug derivative is conjugated to microparticles in solution, and propoxyphene polyclonal antibody (goat) is solubilized in buffer. In the absence of sample drug, free antibody binds to drug- microparticle conjugates causing the formation of particle aggregates. As the aggregation reaction proceeds in the absence of sample drug, the absorbance increases. When a urine sample contains the drug in question, this drug competes with the particle-bound drug derivative for free antibody. Antibody bound to sample drug is no longer available to promote particle aggregation, and subsequent particle lattice formation is inhibited. The presence of sample drug diminishes the increasing absorbance in proportion to the concentration of drug in the sample. Sample drug content is determined relative to the value obtained for a known cutoff concentration of drug.

The assay employed in the 'Rapid One'-Propoxyphene Test is based on the same principle of highly specific reactions between antigens and antibodies. This assay is a one-step, competitive, immunoassay for the detection of propoxyphene and its metabolite norpropoxyphene in human urine. The test device consists of a membrane strip onto which a drug conjugate has been immobilized and a colloidal goldmulti-antibody complex is dried at one end of the membrane. In the absence of any drug in the urine sample, the colloidal gold-antibody complex moves with the urine by capillary action to contact the immobilized drug conjugates. Antibody-antigen reactions occur forming visible lines in the 'test' area. When drug is present in the urine sample, the drug or metabolite will compete with its corresponding drug conjugate in the test area for the limited antibody sites on the colloidal gold-labeled antibody complex. If sufficient amount of drug is present, it will fill all of the available antibody binding sites, thus preventing attachment of the labeled antibody to the drug conjugate. An absence of a color band (line) in the 'test' area is indicative of a positive result. A control band (line), comprised of a different antibody/antigen reaction, is present on the membrane strip. The control line is not influenced by the presence or absence of drug in the urine, and therefore, should be present on all reactions. A negative urine will produce two colored bands, and a positive sample will produce only one band.

Propoxyphene is an in vitro diagnostic assay for the qualitative analysis of Propoxyphene in human urine. The assay is a homogeneous enzyme, immunoassay with a 300 ng/ml, cutoff. The assay is based on competition between drug in the specimen and drug labeled with the enzyme glucose-6-phosphate dehydrogenase (G6PDH) for antibody binding sites. Enzyme activity decreases upon binding to the antibody, so the drug concentration in the specimen can be measured in terms of enzyme activity. Active enzyme converts NAD to NADH, resulting in an absorbance change that can be measured spectrophotometrically.
