A variety of studies are available for the assessment of patients with possible platelet disorders. A complete blood count and peripheral blood smear are the key laboratory components of the diagnosis of immune thrombocytopenic purpura (ITP) and thrombotic thrombocytopenic purpura (TTP). In pediatric patients, immunoglobulin assays are often performed to exclude common variable immune deficiency (CVID) as a cause of ITP. [16]
