Test Name: BRAF Mutation Analysis 


Methodology: Molecular Genetics


Test Description

Bi-directional sequencing of exon 15 of the BRAF gene, which includes qualitative detection of V600 mutations E, K, D, and others, plus other significant exon 15 mutations. For solid tumors, tumor enrichment is performed before extraction.


Specimen Requirements

•Peripheral blood: 4 mL in EDTA tube.
•Bone marrow: 2 mL in EDTA tube.
•FFPE 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.
•Fine needle aspirate (FNA): Requisition must note specimen is FNA. Fresh cells in suspension, unstained air-dried smears (approx. 6-8 slides), or FFPE cell blocks are acceptable if pathologist attaches note verifying sample has >30% tumor or abnormal cells (required). Minimum 10^6 cells.


Storage and Transport

Use cold pack for transport, making sure cold pack is not in direct contact with specimen. All slides can be packed at room temperature
