Hematology is the study of blood and its disorders. Hematologists, board-certified internists, look specifically at blood components such as blood count, and blood and bone marrow cells. Hematology tests can help diagnose anemia, hemophilia, blood-clotting disorders, and leukemia.

Common Hematology Tests:

  • Complete blood count (CBC), which includes: white blood cell count (WBC) red blood cell count (RBC) platelet count hematocrit red blood cell volume(HCT) hemoglobin concentration (HB) - the oxygen-carrying pigment in red blood cells differential blood count
  • Platelet count
