The diagnosis of AML requires the identification of 20% or more leukemic blasts in the bone marrow. Further analysis then must separate AML from acute lymphoblastic leukemia by showing evidence for commitment to the myeloid lineage.
Testing is ordered to detect the Philadelphia (Ph) chromosome and BCR-ABL1 gene sequence. It is used to help diagnose CML and specific types of ALL and, rarely, acute myeloid leukemia (AML) in which the BCR-ABL1 gene sequence is present (BCR-ABL1-positive).
