BRAF Codon 600 Mutation Detection by Pyrosequencing
2002498
 
Ordering Recommendation
Evaluate suspected Lynch syndrome. Use to predict effectiveness of therapies targeting the EGFR pathway. Evaluate thyroid specimens (tissue blocks or formalin-fixed, paraffin-embedded cell blocks prepared from fine needle aspirates [FNA]) for BRAF mutations for purpose of diagnosis, prognosis, and possible therapeutics. For endometrial tissue evaluation, refer to MLH1 Promoter Methylation, Paraffin (2002499). For FNA direct smears, the preferred test is BRAF V600E Mutation Detection by Allele-Specific PCR, Fine Needle Aspirate (2006516).
