JAK2 (V617F) Mutation by ddPCR, Qualitative
Also known as: JAK2 QUAL
Use
This test aids in the workup of suspected myeloproliferative neoplasms by detecting the JAK2 V617F mutation, which is present in patients with these neoplasms. Detection of this mutation helps confirm the diagnosis and guide treatment strategies for conditions such as polycythemia vera, essential thrombocythemia, and primary myelofibrosis.
Special Instructions
Not provided.
Limitations
This assay detects only the JAK2 V617F c.1849G>T mutation. Variants in other genes or other JAK2 variants are not detected or reported. Samples with mutation levels below 0.5% may not be detected. Results must be interpreted in the context of morphological and other clinical findings and are not solely diagnostic for malignancy. The test has not been FDA cleared or approved but is performed in a CLIA-certified lab.
