The first screening diagnostic tests performed to detect hematological or immunological dysfunction are a complete blood count (CBC)with differential and a coagulation profile.The CBC evaluates the cellular components of blood.The CBC reports the total RBC count and RBC indices,hematocrit,hemoglobin,WBC count and differential,platelet count,and cell morphologies.The most invasive microscopic examinations of the bone marrow or lymph nodes are reserved for circumstances when laboratory tests are inconclusive or when an abnormality in cellular maturation is suspected (e.g.,aplastic anemia,leukemia,or lymphoma).A differential laboratory test is not done without the CBC first.A bone marrow biopsy is unwarranted; it would be performed only if preliminary studies indicated a hematological problem.
