The INFINITI CYP2C19 Assay is an in vitro diagnostic test for the identification of a patient's CYP450 2C19 genotype in genomic deoxyribonucleic acid (DNA) obtained from EDTA-anticoagulated whole blood samples. The INFINITI CYP2C19 Assay is a qualitative assay for use in clinical laboratories upon prescription by the attending physician. The INFINITI CYP2C19 Assay is indicated for use as an aid to clinicians in determining therapeutic strategy for therapeutics that are metabolized by the CYP450 2C19 gene product, specifically *2, *3, *17. The INFINITI CYP2C19 Assay is not indicated to be used to predict drug response or non-response.

The INFINITI CYP2C19 Assay is an in vitro diagnostic device which utilizes proprietary film-based microarray technology combined with process automation, reagent management, and software technology for the detection and genotyping of the 2C19 *2, *3, and *17 mutations in genomic deoxyribonucleic acid (DNA) obtained from EDTA-anticoagulated whole blood samples. The INFINITI CYP2C19 Assay is comprised of the BioFilmChipTM Microarray, the Intellipac Reagent Module and the PCR Amplification Mix. The INFINITI CYP2C19 Assay should be run using the AutoGenomics INFINITI Analyzer. The BioFilmChip Microarray consists of a polyester film coated with proprietary multi-layer components designed for DNA analysis. The layers have been designed to provide a versatile surface to enhance test performance. There can be up to 240 spots per microarray with each spot representing a different allele. The microarrays are designed to be assay specific. The Intellipac Reagent Module contains up four reservoirs that house the test reagents and has an integrated memory chip. Information on the reagent such as lot number, expiration date and remaining tests, are archived in the memory. The PCR Amplification Mix consists of the reagents needed for the PCR amplification step of the assay. The INFINITI CYP2C19 Assay is based on the following processes: (a) DNA extraction (b) PCR amplification of purified DNA from human genomic DNA (c) Labeling of the amplified product (allele specific primer extension) (d) Hybridization of the labeled amplified product to a microarray by signature Tag/Capture probe hybridization under isothermal conditions. (e) Scanning of the microarray (f) Signal detection and analysis Steps (c) through (f) are automated by the INFINITI Analyzer. The INFINITI Analyzer automates the 2C19 assay and integrates all the discrete processes of sample (PCR amplicon) handling, reagent management, hybridization, and results The assays are processed automatically and read by the built-in confocal analysis. microscope. Results are analyzed and presented as genotype calls.

The INFINITI 2C9 & VKORC1 Multiplex Assay for Warfarin is an in vitro diagnostic test for the detection and genotyping of the *2 and *3 CYP4502C9 genetic variants and the VKORC1 3673 (-1639) intronic variant in genomic deoxyribonucleic acid (DNA) obtained from EDTA-anticoagulated whole blood samples. The INFINITI 2C9 & VKORC1 Multiplex Assay for Warfarin is a qualitative assay for use in clinical laboratories upon prescription by the attending physician. The INFINITI 2C9 & VKORC1 Multiplex Assay for Warfarin is indicated for use to identify individuals at risk for sensitivity to warfarin.

The INFINITI 2C9 & VKORC1 Multiplex Assay for Warfarin is an in vitro diagnostic device which utilizes proprietary film-based microarray technology combined with process automation, reagent management, and software technology for the detection and genotyping of the 2C9*2, 2C9*3, and VKORC1 3673 (-1639) mutations from EDTA-anticoagulated whole blood samples.
