Label	Id	Description
Anemia	D000740	[A reduction in the number of circulating ERYTHROCYTES or in the quantity of HEMOGLOBIN.]
Hematologic Diseases	D006402	[Disorders of the blood and blood forming tissues.]
Anemia, Aplastic	D000741	[A form of anemia in which the bone marrow fails to produce adequate numbers of peripheral blood elements.]
Bone Marrow Diseases	D001855	[Diseases involving the BONE MARROW.]
Anemia, Dyserythropoietic, Congenital	D000742	[A familial disorder characterized by ANEMIA with multinuclear ERYTHROBLASTS, karyorrhexis, asynchrony of nuclear and cytoplasmic maturation, and various nuclear abnormalities of bone marrow erythrocyte precursors (ERYTHROID PRECURSOR CELLS). Type II is the most common of the 3 types; it is often referred to as HEMPAS, based on the Hereditary Erythroblast Multinuclearity with Positive Acidified Serum test.]
Anemia, Hemolytic, Congenital	D000745	[Hemolytic anemia due to various intrinsic defects of the erythrocyte.]
Anemia, Hemolytic	D000743	[Acquired anemia due to destruction of red blood cells by physical trauma such as FIBRIN strands in the blood vessels, artificial heart valve, AORTIC COARCTATION. I can also be associated with hematologic diseases such as DISSEMINATED INTRAVASCULAR COAGULATION; HEMOLYTIC-UREMIC SYNDROME; and THROMBOTIC THROMBOCYTOPENIC PURPURA., A condition of inadequate circulating red blood cells (ANEMIA) or insufficient HEMOGLOBIN due to premature destruction of red blood cells (ERYTHROCYTES).]
Anemia, Hemolytic, Autoimmune	D000744	[Acquired hemolytic anemia due to the presence of AUTOANTIBODIES which agglutinate or lyse the patient's own RED BLOOD CELLS.]
Anemia, Hemolytic, Congenital Nonspherocytic	D000746	[Any one of a group of congenital hemolytic anemias in which there is no abnormal hemoglobin or spherocytosis and in which there is a defect of glycolysis in the erythrocyte. Common causes include deficiencies in GLUCOSE-6-PHOSPHATE ISOMERASE; PYRUVATE KINASE; and GLUCOSE-6-PHOSPHATE DEHYDROGENASE.]
Anemia, Hypochromic	D000747	[Anemia characterized by a decrease in the ratio of the weight of hemoglobin to the volume of the erythrocyte, i.e., the mean corpuscular hemoglobin concentration is less than normal. The individual cells contain less hemoglobin than they could have under optimal conditions. Hypochromic anemia may be caused by iron deficiency from a low iron intake, diminished iron absorption, or excessive iron loss. It can also be caused by infections or other diseases, therapeutic drugs, lead poisoning, and other conditions. (Stedman, 25th ed; from Miale, Laboratory Medicine: Hematology, 6th ed, p393)]
Anemia, Macrocytic	D000748	[Anemia characterized by larger than normal erythrocytes, increased mean corpuscular volume (MCV) and increased mean corpuscular hemoglobin (MCH).]
Anemia, Megaloblastic	D000749	[A disorder characterized by the presence of ANEMIA, abnormally large red blood cells (megalocytes or macrocytes), and MEGALOBLASTS.]
Anemia, Myelophthisic	D000750	[Anemia characterized by appearance of immature myeloid and nucleated erythrocytes in the peripheral blood, resulting from infiltration of the bone marrow by foreign or abnormal tissue.]
Anemia, Neonatal	D000751	[The mildest form of erythroblastosis fetalis in which anemia is the chief manifestation.]
Anemia, Pernicious	D000752	[A megaloblastic anemia occurring in children but more commonly in later life, characterized by histamine-fast achlorhydria, in which the laboratory and clinical manifestations are based on malabsorption of vitamin B 12 due to a failure of the gastric mucosa to secrete adequate and potent intrinsic factor. (Dorland, 27th ed)]
Vitamin B 12 Deficiency	D014806	[A nutritional condition produced by a deficiency of VITAMIN B 12 in the diet, characterized by megaloblastic anemia. Since vitamin B 12 is not present in plants, humans have obtained their supply from animal products, from multivitamin supplements in the form of pills, and as additives to food preparations. A wide variety of neuropsychiatric abnormalities is also seen in vitamin B 12 deficiency and appears to be due to an undefined defect involving myelin synthesis. (From Cecil Textbook of Medicine, 19th ed, p848)]
Anemia, Refractory	D000753	[A severe sometimes chronic anemia, usually macrocytic in type, that does not respond to ordinary antianemic therapy.]
Myelodysplastic Syndromes	D009190	[Clonal hematopoietic stem cell disorders characterized by dysplasia in one or more hematopoietic cell lineages. They predominantly affect patients over 60, are considered preleukemic conditions, and have high probability of transformation into ACUTE MYELOID LEUKEMIA.]
Anemia, Refractory, with Excess of Blasts	D000754	[Chronic refractory anemia with granulocytopenia, and/or thrombocytopenia. Myeloblasts and progranulocytes constitute 5 to 40 percent of the nucleated marrow cells.]
Anemia, Sickle Cell	D000755	[A disease characterized by chronic hemolytic anemia, episodic painful crises, and pathologic involvement of many organs. It is the clinical expression of homozygosity for hemoglobin S.]
