Overview

Laboratory Findings

  • Peripheral blood smear - immature blast cells can be identified
  • Liver function tests
  • Renal function tests
  • Coagulation studies - prolonged bleeding and clotting time
  • Bone marrow examination - is often performed to identify the type of abnormal blood cells; however, if there are many leukemic cells circulating in the peripheral blood, a bone marrow biopsy may not be necessary.

Marrow or blood is examined via light microscopy as well as flow cytometry to diagnose the presence of leukemia, to differentiate acute myeloid leukemia from other types of leukemia (e.g. acute lymphoblastic leukemia), and to classify the subtype of disease.

The diagnosis and classification of acute myeloid leukemia can be challenging, and should be performed by a qualified hematopathologist or hematologist. In straightforward cases, the presence of certain morphologic features (such as Auer rods) or specific flow cytometry results can distinguish acute myeloid leukemia from other leukemias; however, in the absence of such features, diagnosis may be more difficult.[1]
