Idiopathic thrombocytopenic purpura other diagnostic studies

A bone marrow examination may be performed on patients over the age of 60 and people who do not respond to treatment, or when the diagnosis is in doubt. The bone marrow biopsy in ITP can show increased (thought not always) megakaryocytes, bizarre giant platelets and platelet fragments. (Large platelets are often seen in the peripheral blood smear though this can be seen in other diseases.) When the spleen is removed it may show increased lymphatic nodularity.
