Which term refers to the study of blood and disorders related to it?

The term that refers to the study of blood and disorders related to it is hematology. This field encompasses the examination of blood components, such as red blood cells, white blood cells, platelets, and plasma, as well as the diagnosis and treatment of blood-related conditions, including anemia, clotting disorders, and hematologic cancers like leukemia and lymphoma. Hematologists are the medical specialists who focus on these areas, working to understand the complexities of blood and its functions in the overall health of the body.

Infectiology pertains to the study of infectious diseases and their pathogens, which is distinct from hematology's focus on blood itself. Immunology involves the study of the immune system and its role in protecting the body from diseases but does not specifically focus on blood disorders. Pathology broadly refers to the study of the nature and causes of diseases, including those affecting blood, but it encompasses a wider range of conditions beyond just blood disorders. Hence, hematology is the most precise and relevant term for the study of blood and its related disorders.
