HelpTest ID BRAFD BRAF V600E/V600K Somatic Mutation Analysis, Tumor
Necessary Information
Pathology report (final or preliminary) must accompany specimen in order for testing to be performed. At minimum, it should contain the following information:
1. Patient name
2. Block number-must be on all blocks, slides and paperwork (can be handwritten on the paperwork)
3. Tissue collection date
4. Source of the tissue
Specimen Required
Preferred:
Specimen Type: Tissue
Container/Tube: Tissue block
Collection Instructions: Submit a formalin-fixed, paraffin-embedded tissue block.
Acceptable:
Specimen Type: Tissue
Container/Tube: Slides
Specimen Volume: 1 stained and 5 unstained
Collection Instructions: Submit 1 slide stained with hematoxylin and eosin and 5 unstained, nonbaked slides with 5-micron thick sections of the tumor tissue.
Useful For
Therapy selection for patients with cancer (eg, melanomas that may respond to BRAF inhibitors, colon cancers than may not respond to EGFR inhibitors)
Aiding in the diagnosis/prognosis of certain cancers (eg, hairy cell leukemia, papillary thyroid cancers, and association with aggressiveness)
Aid in determining risk for Lynch syndrome (eg, an adjunct to negative MLH1 germline testing in cases where colon tumor demonstrates MSI-H and loss of MLH1 protein expression)
