LeukoVantage, Myeloid
Also known as: Myelodysplastic Syndrome (MDS), Myeloproliferative Neoplasms (MPN), Acute Myeloid Leukemia (AML)
Use
The LeukoVantage Myeloid test evaluates mutations in 48 genes associated with acute myeloid leukemia (AML), myelodysplastic syndromes (MDS), and myeloproliferative neoplasms (MPNs). It supports diagnosis, prognosis, and disease monitoring by detecting relevant mutations in these neoplasms. The mutational profile can aid in classification of disease when traditional markers such as BCR‑ABL1, JAK2, CALR, CSF3R, and MPL are absent.
Special Instructions
Not provided.
Limitations
Although this next-generation sequencing assay provides sensitive mutation detection with a limit of detection of approximately 5%, including for MLL PCR targets, it has not been specifically validated for assessing minimal residual disease. Results depend on adequate sample quality and quantity.
