The medical world is full of different doctors and branches of medicine. One study is hematology which studies the blood, blood forming organs, and blood diseases. Hematology looks at the pathology and clinical lab results to determine what illness a person might suffer. The most important aspect of hematology is the study of blood diseases which affect blood cells, hemoglobin, blood proteins, and coagulation.
A hemophiliac is a person whose blood will not coagulate properly. In the field of hematology a doctor or even a research lab is going to look for solutions to the diseases. A hematology lab will look at blood films and bone marrow under the microscope to determine what is wrong. Often a doctor and a hematopathologist will work together to find a diagnosis.
