| incompatible blood transfusion reaction | A syndrome due to intravascular haemolysis of transfused blood by serum antibodies of the recipient, which react with an antigen of the donor red cells; characterised by chills, fever (often with urticaria), backache or muscle cramps, haemoglobinaemia, haemoglobinuria, and oliguria, which may result in acute renal failure, DIC, and death.

| occult blood | Blood that is in the faeces or vomitus that is not obvious by general inspection. Used as a diagnostic screening test for colon cancer. Tests for occult blood are generally colourimetric. Stool sample will turn blue when a particular chemical reagent is mixed with the specimen on test paper. Kits for measuring occult blood in the stools are now available at most drug stores. (27 Sep 1997) |
| effective renal blood flow | The amount of blood flowing to the parts of the kidney that are involved with production of constituents of urine. (05 Mar 2000) |
| exchange transfusion, whole blood | Repetitive withdrawal of small amounts of blood and replacement with donor blood until a large proportion of the blood volume has been exchanged. Used in treatment of foetal erythroblastosis, hepatic coma, sickle cell anaemia, disseminated intravascular coagulation, septicaemia, burns, thrombotic thrombopenic purpura, and fulminant malaria.

| Kell blood group | <haematology, immunology> Blood type classification based on a group of erythrocyte antigens that is characterised by an antibody called anti-K. Multiple erythrocytic antigens that comprise at least three pairs of alternates and amorphs, determined by one complex gene or possibly several genes at closely linked loci. The system is important in transfusion reactions. Its expression involves the X chromosome. (21 Jun 2000) |
