Description
Why It’s Done
The MPO test is primarily used to:
• Aid in the diagnosis of acute myeloid leukemia (AML).
• Differentiate AML from acute lymphoblastic leukemia (ALL).
• Evaluate patients with unexplained high white blood cell counts, anemia, thrombocytopenia, or other symptoms suggestive of leukemia.
• Support other findings from bone marrow examination and flow cytometry in leukemia classification.
This test is crucial in guiding proper treatment, as AML and ALL require different therapeutic approaches.
Preparation
• No special preparation is usually needed.
• A blood sample or bone marrow aspirate will be collected by a healthcare provider.
• Inform the healthcare provider about any medications being taken, recent infections, or prior cancer treatments, if applicable.
