WebABO-incompatible cryoprecipitate can be used with caution – particularly in large volumes. If large volumes of ABO-incompatible cryoprecipitate are used, the recipient may develop a positive direct antiglobulin test and, very rarely, develop haemolysis. Plasma components that have low titre anti-A or anti-B pose a lower risk of haemolysis. WebTests called coagulation tests are used to detect the lupus anticoagulant (LA). Remember that even though the lupus anticoagulant causes the blood to clot more easily in vivo (i.e., in a person’s body), they actually cause prolonged clotting times in vitro (i.e., in a test tube).
