Test Name: KRAS & BRAF Mutation Analysis
Methodology: Molecular Genetics
Concurrent analysis of KRAS and BRAF gene regions including KRAS exons 2 and 3 (with mutation detection in codons 12, 13, 59, and 61) and BRAF exon 15 to detect V600 mutations and more. Tumor enrichment is performed before extraction.
FFPE solid tumor tissue: Paraffin block is preferred. Alternatively, send 1 H&E slide plus 5-10 unstained slides cut at 5 or more microns. Please use positively-charged slides and 10% NBF fixative. Do not use zinc fixatives.
Storage and Transport
Use cold pack for transporting block during summer to prevent block from melting. Slides can be packed at room temperature.
