Hematopathology is the branch of pathology which studies diseases of hematopoietic cells (see below). A hematopathologist looks at peripheral blood smears, bone marrow aspirates and biopsies, lymph nodes, and other tissues, and uses his/her expertise to diagnose diseases such as lymphomas and leukemias. The hematopathologist uses traditional microscopy to look at the specimen, but also relies on laboratory values, immunohistochemistry, flow cytometry, and molecular diagnostic tests to make the most accurate diagnosis. The hematopathologist works closely with the hematologist/oncologist specialty doctor who sees the patient and decides on the best treatment based upon the diagnosis.

Hematopathologist’s work list:

- Diagnose diseases of lymph nodes, spleen, bone marrow and other lymphohematopoietic tissues.

- Diagnose diseases of blood.

- Diagnose disease of bleeding and clotting disorders.

- Manage hematoly laboratory, sometimes, molecular laboraotry and flow cytometry laboratory.

- Research on blood and lymphoid diseases.

- Teaching phycisians, students and other healthcare trainees.
