Answer

Bone marrow aspiration and biopsy in patients with immune thrombocytopenic purpura (ITP) demonstrates a normal-to-increased number of megakaryocytes in the absence of other significant abnormalities. The value of bone marrow evaluation for a diagnosis of ITP is unresolved, and more data are needed to establish clear guidelines. [4]
