It focuses on the diagnosis, treatment, and prevention of diseases related to the production, function, and disorders of the blood cells. It encompasses a wide range of topics, including red and white blood cell counts, platelet counts, blood chemistry, and blood clotting. Additionally, hematology is concerned with the diseases and conditions that affect hematopoiesis (the production of blood cells), such as anemia, hemophilia, and leukemia. Hematology also includes the study of the effects of hematopoietic drugs, transfusion therapies, and stem cell transplants. Hematology provides insight into what your red blood cell count means. A normal red blood cell count (RBC) should fall within the range of 4.2-5.4 million cells per microliter for men and 3.9-5.2 million cells per microliter for women.
