<unk>  is the branch of pathology which studies diseases of hematopoietic cells (see below).  A<unk> st 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<unk> st 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<unk> st works closely with the hematologist/oncologist specialty doctor who sees the patient and decides on the best treatment based upon the diagnosis.
