Additional Technical Information

Ordering Recommendation

Use to detect activating BRAF mutations at codon 600, which can indicate responsiveness to BRAF inhibitors in melanomas or resistance to anti-EGFR therapy in colorectal cancer. Useful to assess prognosis and to guide treatment decisions in certain thyroid cancers. Can also be used within the Lynch syndrome reflex testing pathway (for colorectal cancer specimens only).

Specimen Required

Patient Preparation
Collect

Tumor tissue.

Specimen Preparation

Tumor Tissue: Formalin fix (10 percent neutral buffered formalin) and paraffin embed tissue. Protect from excessive heat. Tissue block will be returned after testing. Transport tissue block or 5 unstained 5 micron slides. (Min: 3 slides). Transport block and/or slide(s) in a tissue transport kit (ARUP Supply # 47808) available online through eSupply using ARUP Connect™or contact ARUP Client Services at (800) 522-2787.

Storage/Transport Temperature

Room temperature. Also acceptable: Refrigerated. Ship in cooled container during summer months.

Unacceptable Conditions

Less than 25 percent tumor. Specimens fixed/processed in alternative fixatives (alcohol, Prefer) or heavy metal fixatives (B-4 or B-5). Decalcified specimens.

Remarks

Include surgical pathology report.
If multiple specimens (blocks or slides) are sent to ARUP, they must be accompanied by one of the following: an order comment indicating that the ARUP pathologist should choose the specimen most appropriate for testing (e.g., "Choose best block"), or individual orders for each sample submitted. A Pathologist Block Selection Fee (ARUP test code 3002076) will be added to orders that utilize the first option. If multiple specimens are sent to ARUP without a request for pathologist block/slide selection or individual orders, they will be held until clarification is provided.

Stability

Ambient: Indefinitely; Refrigerated: Indefinitely; Frozen: Unacceptable
