Device Description
IMMULITE® Cannabinoids is a solid-phase, chemiluminescent enzyme immunoassay designed for use with the IMMULITE" Automated Analyzer for the semiquantitative and qualitative measurement for cannabinoids and metabolites in urine. It is intended strictly for in vitro diagnostic use in the context of a program involving an established confirmatory test for tetrahvdrocannabinol (THC. cannabis, marijuana) and its metabolites. IMMULITE® Cannabinoids is a solid-phase. chemiluminescent immunoassay. The solid phase, a polystyrene bead enclosed within an IMMULITE® Test Unit, is coated with a monoclonal antibody specific for cannabinoids. The patient sample and alkaline phosphatase-conjugated 11-nor-A -tetrahvdrocannabinol-9-carboxylic acid (THCA) are simultaneously introduced into the Test Unit, and incubated for 30 minutes at 37°C with intermittent agitation. During this time, cannabinoids in the sample compete with the enzyme-labeled THC for a limited number of antibody binding sites on the bead. Unbound enzyme conjugate is then removed by a centrifugal wash, after which substrate is added and the Test Unit is incubated for a further 10 minutes. The chemiluminescent substrate, a phosphate ester of adamantyl dioxetane, undergoes hydrolysis in the presence of alkaline phosphatase to vield an unstable intermediate. The continuous production of this intermediate results in a sustained emission of light, thus improving precision by providing a window for multiple readings. The bound complex - and thus also the photon output as measured by the luminometer - is inversely proportional to the concentration of cannabinoids in the sample.

Technological Comparison to Predicate:

The IMMULITE* Cannabinoids is a chemiluminescent immunoassay. The technology of the IMMULITE® Cannabinoids assay is identical to the technology used in previously cleared and commercially marketed IMMULITE® products.

IMMULITE® Cannabinoids is a solid-phase. chemiluminescent immunoassay. The solid phase, a polystyrene bead enclosed within an IMMULITE® Test Unit, is coated with a monoclonal antibody specific for cannabinoids. The patient sample and alkaline phosphatase-conjugated 11-nor-A -tetrahvdrocannabinol-9-carboxylic acid (THCA) are simultaneously introduced into the Test Unit, and incubated for 30 minutes at 37°C with intermittent agitation. During this time, cannabinoids in the sample compete with the enzyme-labeled THC for a limited number of antibody binding sites on the bead. Unbound enzyme conjugate is then removed by a centrifugal wash, after which substrate is added and the Test Unit is incubated for a further 10 minutes.

The chemiluminescent substrate, a phosphate ester of adamantyl dioxetane, undergoes hydrolysis in the presence of alkaline phosphatase to vield an unstable intermediate. The continuous production of this intermediate results in a sustained emission of light, thus improving precision by providing a window for multiple readings. The bound complex - and thus also the photon output as measured by the luminometer - is inversely proportional to the concentration of cannabinoids in the sample.

Abuscreen Online Automated Assays are based on the kinetic interaction of microparticles in a solution (KIMS) as measured by changes in light transmission. In the absence of sample drug, free antibody binds to drug-microparticle conjugates, causing the formation of particle aggregates When a urine sample containing the drug in question is present, 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.

As the aggregation reaction proceeds in the absence of sample drug, the absorbance change increases. Conversely the presence of sample drug diminishes the increasing absorbance in proportion to the concentration of drug in the sample drug content is determined relative to the value obtained for a known cutoff concentration of drug.

The AxSYM Cannabinoids assay utilizes fluorescence Polarization Immunoassay (FPIA) technology. In the FPIA reaction process, specimen analyte-tracer compete for binding sites on antibodies. If the specimen contains a high concentration of the analyte, then specimen analyte binds to the antibodies, leaving the analyte-tracer unbound. If the specimen contains a low concentration (or no concentration) of the analyte. then few or no analyte molecules bind to the antibodies. leaving the antibodies open for the analyte-tracer to bind. FPIA optics measure the change in polarized light to determine the concentration of unbound analyte-tracers. and therefore the concentration of analytes in the specimen (fluorescence polarization).
