| Donath-landsteiner | <investigation> A serologic blood test used to detect antibody in serum in cases of suspected paroxysmal cold haemoglobinuria. The antibody is directed toward the P-antigen complex which is located on the surface of red blood cells. In some way, cold temperatures trigger the antibody to bind to this site. (15 Nov 1997) |
|---|---|
| Donath-Landsteiner cold autoantibody | An autoantibody of the IgG class responsible for paroxysmal cold haemoglobinuria; it is adsorbed to red cells only at temperatures of 20°C or lower, causing the red cells to lyse in the presence of complement at higher temperatures; it has only slight agglutinating properties in spite of its marked lytic activity, and has a specificity within the blood group P; it is also occasionally present for short periods of time following measles and other infections, and formerly was frequently associated with syphilis. Synonym: cold haemolysin. (05 Mar 2000) |
| Donath-Landsteiner phenomenon | The haemolysis which results in a sample of blood of a subject of paroxysmal haemoglobinuria when the sample is cooled to around 5°C and then warmed again. (05 Mar 2000) |

an IgG antibody directed against the P blood group antigen; it binds to red cells at low temperatures and induces complement-mediated lysis on warming, and is responsible for hemolysis in paroxysmal cold hemoglobinuria.

(for paroxysmal cold hemoglobinuria): a test based on the fact that the blood of patients with this disease contains complement-dependent iso- and autohemolysin (Donath-Landsteiner antibody) which unites with red cells only at low temperatures (2° to 10°C), hemolysis occurring only after warming to 37°C.
