Thyroid, FNA Cytomorphology with Molecular Reflex
Clinical Use
Order TestUse
This assay provides morphologic review along with reflexive molecular testing for thyroid specimens obtained by fine needle aspiration (FNA). Molecular testing—including analysis of BRAF V600E mutation, RET/PTC rearrangement, PAX8/PPARγ translocation, and RAS mutations—is triggered based on cytologic findings to support diagnosis of papillary and follicular thyroid neoplasms.
