Hematologic Diseases Categories.
Canadian Medical Guide Definition Anemia - A reduction in the number of circulating erythrocytes or in the quantity of hemoglobin.
Canadian Medical Guide Definition Blood Coagulation Disorders - Hemorrhagic and thrombotic disorders that occur as a consequence of abnormalities in blood coagulation due to a variety of factors sych as COAGULATION PROTEIN DISORDERS; BLOOD PLATELET DISORDERS; BLOOD PROTEIN DISORDERS or nutritional conditions.
Canadian Medical Guide Definition Blood Group Incompatibility - A mismatch between donor and recipient blood. Antibodies present in the recipient's serum are directed against antigens in the donor product. Such a mismatch may result in a transfusion reaction in which, for example, donor blood is hemolyzed. (From Saunders Dictionary & Encyclopedia of Laboratory Medicine and Technology, 1984)
Canadian Medical Guide Definition Blood Platelet Disorders - Disorders caused by abnormalities in platelet count or function.
Canadian Medical Guide Definition Blood Protein Disorders
Canadian Medical Guide Definition Bone Marrow Diseases
Canadian Medical Guide Definition Hemoglobinopathies - A group of inherited disorders characterized by structural alterations within the hemoglobin molecule.
Canadian Medical Guide Definition Hemorrhagic Disorders - Spontaneous or near spontaneous bleeding caused by a defect in clotting mechanisms (BLOOD COAGULATION DISORDERS) or another abnormality causing a structural flaw in the blood vessels (VASCULAR HEMOSTATIC DISORDERS).
Canadian Medical Guide Definition Leukocyte Disorders - Disordered formation of various types of leukocytes or an abnormal accumulation or deficiency of these cells.
Canadian Medical Guide Definition Methemoglobinemia - The presence of methemoglobin in the blood, resulting in cyanosis. A small amount of methemoglobin is present in the blood normally, but injury or toxic agents convert a larger proportion of hemoglobin into methemoglobin, which does not function reversibly as an oxygen carrier. Methemoglobinemia may be due to a defect in the enzyme NADH methemoglobin reductase (an autosomal recessive trait) or to an abnormality in hemoglobin M (an autosomal dominant trait). (Dorland, 27th ed)
Canadian Medical Guide Definition Pancytopenia - Deficiency of all three cell elements of the blood, erythrocytes, leukocytes and platelets.
Canadian Medical Guide Definition Polycythemia - An increase in the total red cell mass of the blood. (Dorland, 27th ed)
Canadian Medical Guide Definition Sulfhemoglobinemia - A morbid condition due to the presence of sulfmethemoglobin in the blood. It is marked by persistent cyanosis, but the blood count does not reveal any special abnormality in the blood. It is thought to be caused by the action of hydrogen sulfide absorbed from the intestine. (Stedman, 25th ed)
Canadian Medical Guide Definition Thrombophilia - A disorder of HEMOSTASIS in which there is a tendency for the occurrence of THROMBOSIS.
