PRECISION DIAGNOSTICS
Purpose/Principle
CHCO Oncology Single Gene Sequence Analysis utilizes next-generation sequencing technology to detect somatic variants in the requested single gene. The assay evaluates the coding regions and adjacent intronic bases of the specified gene for DNA variants. The assay is designed to detect SNV and small indel events with >99% accuracy down to a 5% minor allelic frequency. Paired tumor normal testing is not available for somatic single gene requests.
