BRAF Gene Mutation Analysis - Melanoma
Also known as: THXID®-BRAF Kit
Use
The THxID™‑BRAF kit is an In Vitro Diagnostic device intended for the qualitative detection of the BRAFV600E and V600K mutations in DNA samples extracted from formalin‑fixed paraffin‑embedded (FFPE) human melanoma tissue. It is a real‑time PCR test on the ABI 7500 Fast Dx system and aids in selecting melanoma patients whose tumors carry BRAFV600E for treatment with dabrafenib (Tafinlar®), and those carrying BRAFV600E or V600K for trametinib (Mekinist™).
Special Instructions
Please provide a copy of the pathology report. Direct any questions regarding this test to customer service at 800‑345‑4363. BRAF testing will be delayed if the pathology report is not received.
Limitations
This assay is able to detect 5% mutation in a background of wild‑type DNA.
