Microsatellite instability

Order Code: 334763

CPT Codes: 81301, G0452

Indication: Help determine whether a tumor more likely occurred as a result of sporadic or inherited pathogenic variants. Aid in the determination of patients who may benefit from analysis in one of several mismatch repair genes

Required Patient Information: Clinical Diagnosis, Surgical Pathology report

Turn Around Time: 10 days

Specimen type: Paraffin embedded tissue 
Methodology: MSI Analysis System, a fluorescent PCR-based assay includes fluorescently labeled primers for co-amplification of five markers to detect microsatellite instability (MSI) in human tumor cells. Samples with ≥40% of the MSI markers altered (≥2 out of 5) are classified as MSI-High (MSI-H).
