Acute lymphoid leukemia
In acute myeloid leukemia, more tests are usually required. Blood tests should be accompanied by a peripheral smear, and doctors typically ask for liver and renal function tests. Blood cultures are sometimes required, depending on the signs and symptoms of the patient, and imaging studies are also useful, especially in cases of infection. Doctors can order a lumbar puncture, an echocardiogram, and other types of specialized tests. However, the definite diagnostic test is the same: a bone marrow aspiration with a biopsy. For classification, it will be important to detect genetic abnormalities in the bone marrow and the lymphoblasts in the peripheral blood. All of this is useful for prognosis, too, and can be ordered more than once, depending on the signs and symptoms of the patients.
