What is hematology?

Hematology is the study of blood and blood disorders. Hematologists and hematopathologists are highly trained healthcare providers who specialize in diseases of the blood and blood components. These include blood and bone marrow cells. Hematological tests can help diagnose anemia, infection, hemophilia, blood-clotting disorders, and leukemia.


Let’s say you had a blood test done. You call the laboratory to see if the results are in, but the receiver says, ”This is chemistry; you need micro” or ”Let me transfer you to hematology.” Did you know there were labs within the lab? There are. Each department within a laboratory specializes in certain tests. Let’s see just what’s going on in the hematology department of the lab.


Hematology¬†(hema- is from the Greek word for ‘blood’) is the study of blood in regard to a person’s health or disease. It includes blood, blood-forming organs, and the proteins involved in bleeding and clotting.


Hematological tests can evaluate numerous conditions involving blood and its components. They can also diagnose inflammation, anemia, infection, hemophilia, blood-clotting disorders, leukemia, and response to chemotherapy, among many other things.
