Collection Instructions In general, the tumor should be a minimum of 0.4 cm in size. Blocks selected for BRAF mutation testing must contain tumor tissue. Areas of tumor must contain at least 50% tumor cells. The lab can remove adjacent non-tumor tissue, so the entire slide does not need 50% tumor cells, just the area with tumor. Contact the laboratory (415-502-3252) if the specimen suitability is uncertain. Label slides with pathology case number and block identification.
Sample type Formalin-fixed, paraffin-embedded tissue. Tissue block or unstained slides. If sending unstained slides, we require five (5) 10-micron tissue sections on uncharged glass slides. One adjacent H&E stained slide should be included. Cytology smears may also be used for testing if there is sufficient tumor present. Contact the laboratory (415-502-3252) if testing on a cytology smear or other sample types is desired.
