What are the diagnostic tests for acute lymphoblastic leukemia?

Bone marrow biopsy : The diagnosis is typically with a bone marrow biopsy, cytogenetics (dna of leukemia cells), and flow cytometry (cell surface markers of leukemia cells).

See below...: A blood test (cbc with morphology) is usually the initial test when a diagnosis of leukemia is suspected. Afterwards, the studies that are necessary for a complete characterization include bone marrow aspiration for morphology, flow cytometry, cytogenetics, and molecular analysis, as well as lumbar puncture for CSF analysis. Other tests may also be necessary on a case-by-case basis.
