Test orders include summary interpretation of all results together.

Clinical Significance

The NeoLAB Myeloid Disorders Profile is a 56-gene panel that targets known mutations associated with acute myeloid leukemia (AML), myeloproliferative neoplasms (MPN), myelodysplastic syndrome (MDS), chronic myelogenous leukemia (CML), chronic myelomonocytic leukemia (CMML) and juvenile myelomonocytic leukemia (JMML). Testing using this panel can aid in making therapy decisions, predicting prognosis, and can be used in clinical research. This is a generic and comprehensive profiling of myeloid neoplasms. In addition, this test can be used for screening and determining if a bone marrow biopsy is an absolute necessity, as well as monitoring disease status and response to therapy. It can also be used for performing molecular studies when a bone marrow sample is inadequate (dry tap, insufficient quantity, or not viable), or not available.

Specimen Requirements

Peripheral blood: 2 x 6 mL EDTA tubes (total 12 mL) or 10 mL in EDTA tube.

Storage and Transportation

Use cold pack for transport, making sure cold pack is not in direct contact with specimen. Ship same day as drawn whenever possible; specimens <72 hours old preferred.
