Hematology is a branch of medicine that deals with the study of causes, treatments, prognosis and prevention of blood-related diseases. It is concerned with the treatment of diseases that affect the production of blood and its constituents including blood cells, hemoglobin, platelets, bone marrow, blood proteins, spleen and blood vessels. The microbiological culture of the blood detects infections that spread through the bloodstream, such as bacteremia and sepsis.
