Processing and Shipping

Specimen Processing:Do not process. Store at room temperature.
Shipping Instructions:Ship at room temperature. Do not refrigerate or freeze.
Stability:Whole blood samples are stable for 5 days at room temperature. Do not refrigerate or freeze.
Test Performed at or Referral Lab Molecular Diagnostics  (UMMC-East Bank)


Reference Range:See interpretive report.
Use:The vast majority of hairy cell leukemia have a BRAF V600E mutation. MAP2K1 mutations are found in hairy cell leukemia variant. It is unclear at this time if MAP2K1 mutations can be found in rare cases of classic hairy cell leukemia.
