| haemoglobin, sickle | An abnormal haemoglobin resulting from the substitution of valine for glutamic acid at position 6 of the beta chain of the globin moiety. The heterozygous state results in sickle cell trait, the homozygous in sickle cell anaemia. (12 Dec 1998) |

| haemoglobinaemia | <haematology> Haemoglobinaemia is a medical condition in which free haemoglobin proteins are present in blood plasma. This occurs when red blood cells (within which haemoglobin is normally found) have been injured while in the blood vessels. Origin: Gr. Haima = blood (09 Oct 1997) |
| haemoglobinaemia paralytica | azoturia of horses |
| haemoglobinocholia | The presence of haemoglobin in the bile. Origin: haemoglobin + G. Chole, bile (05 Mar 2000) |
| haemoglobinolysis | Destruction or chemical splitting of haemoglobin. Synonym: haemoglobinopepsia. Origin: haemoglobin + G. Lysis, dissolution (05 Mar 2000) |
| haemoglobinometer | Same as Hemochromometer. Origin: Haemoglobin. Source: Websters Dictionary (01 Mar 1998) |
| haemoglobinometry | Measurement of haemoglobin concentration in blood. (12 Dec 1998) |
| haemoglobinopathy | <disease, haematology> Disorder due to abnormalities in the haemoglobin molecule, the best known being sickle cell anaemia in which there is a single amino acid substitution (valine for glutamate) in position 6 of the beta chain. In other cases one of the globin chains is synthesised at a slower rate, despite being normal in structure. See: thalassaemia. Origin: Gr. Pathos = disease (18 Nov 1997) |
| haemoglobinopepsia | Synonym: haemoglobinolysis. Origin: haemoglobin + G. Pepsis, digestion (05 Mar 2000) |
| haemoglobinophilic | Denoting certain microorganisms that cannot be cultured except in the presence of haemoglobin. Origin: haemoglobin + G. Phileo, to love (05 Mar 2000) |
| haemoglobins, abnormal | Haemoglobins altered in their genetically determined molecular structure, resulting in a characteristic complex of vlinival and laboratory abnormalities. The specific features of the abnormal haemoglobins are related to variation of the composite globin polypeptide chains. (12 Dec 1998) |
| haemoglobinuria | Haemoglobin in the urine. (12 Dec 1998) |
| haemoglobinuria, paroxysmal | Disorder characterised by intravascular haemolysis and haemoglobinuria. Some cases occur on exposure to cold and are due to the presence of an autohemolysin in the serum. Other cases are more marked during or immediately after sleep and are considered to be due to an acquired intracorpuscular defect. (12 Dec 1998) |
| haemoglobinuric | Relating to or marked by haemoglobinuria. (05 Mar 2000) |
| haemoglobinuric fever | A condition, now uncommon, resulting from Plasmodium falciparum infection (malignant tertian malaria with severe haemolysis); frequently seen in Caucasians after interrupted treatment with quinine. Synonym: blackwater fever, haemoglobinuric fever, West African fever. (05 Mar 2000) |
