Bone marrow aspiration is an important test that helps physicians diagnose hematological disorders. Unexpected pancytopenia, which is the simultaneous presence of low counts of all three blood cell types (white blood cells, red blood cells, and platelets), is a valid indication for performing a bone marrow aspiration. In such cases, bone marrow aspiration can help determine the underlying cause of pancytopenia by providing important diagnostic clues, such as abnormal cell morphology, increased or decreased cellularity, or infiltrative disorders such as leukemia or lymphoma. Iron deficiency and folate deficiency are diagnosed by measuring the levels of iron and folate in the blood, respectively. Leukocytosis from a severe infection is not an indication for bone marrow aspiration but may warrant further testing to determine the underlying cause.
