Sequential testing panel including qualitative detection of JAK2 V617F, JAK2 Exon 12-14, CALR exon 9, and MPL exon 10. Testing proceeds by reflex, with the next step triggered by a negative result or a weakly positive result of uncertain clinical significance; no further testing is performed once an informative result is obtained. Testing is performed on plasma for increased sensitivity whenever possible. Tests may also be ordered individually (see separate listing). Testing is approved for specimens from the state of New York.
Comprehensive testing to identify mutations associated with the myeloproliferative neoplasms polycythemia vera (PV), essential thrombocythemia (ET), and primary myelofibrosis (PMF). Mutation analysis helps differentiate reactive conditions from MPNs, may provide prognostic information, and may help distinguish ET and PMF from PV.
