Hematopathology is the study of diseases of the cells that make up our blood.

These cells originate in the bone marrow and become:

  • White blood cells
  • Red blood cells
  • Platelets

White blood cells are present in many important structures of the body, like lymph nodes, and are major components of the immune system.

When disease invades, the body sends these cells to fight bacteria and viruses by producing antibodies against the infection.

Blood cells can occasionally become abnormal; in some cases, abnormal blood cells give rise to cancers such as leukemia.

The Role of the Hematopathologist

Hematopathologists are specially trained to diagnose diseases of the blood cells. They use specialized tests such as flow cytometry studies and immunohistochemistry.

The hematopathologist uses the results of these tests to diagnose infections and diseases of the blood, lymph nodes and bone marrow.
