Technical Information
Test Procedure: Help
Real-time PCR genotyping using Taqman probes from Life Tech on the Quant Studio 12K Flex Real-time PCR machine for the detection of specific alleles in genotyping the CYP2C19 gene
Availability: Help
Tests performed
Entire test performed in-house
Analytical Validity: Help
Validation study revealed 100% specificity and sensitivity for the samples tested
Assay limitations: Help
This analysis does not detect all variants with known impact on enzyme expression and activities. Non-genetic factors, variations in the other genes involving drug metabolism, or drug-drug interactions are not measured by this assay. The minimum depth of coverage is 16 reads. Phasing for alleles is not performed. the diplotype … View more
