It was found that the use of a phospholipid dependent prothrombin activator purified from the venom of snakes belonging to the Elapidae family, especially members of the Oxyuranus and Psuedonaja genera is most useful in tests for the determination of Lupus Anticoagulant. Based on this, several clotting, chromogenic and immunochromogenic tests have been developed.

Based on this, several clotting, chromogenic aria immunochromogenic tests have been developped.

Test for lupus anticoagulant

A method for the preparation of a phospholipid-dependent prothrombin activator from the venom of snakes belonging to the Elapidae family, the activator comprising an increased plasma clotting activity in the presence of phospholipids and calcium ions; a reduced activity in the presence of Lupus Anticoagulant; an ability to facilitate clotting in a normal clotting time in the presence of platelet poor plasma, the plasma having normal or decreased levels of factor V, VII, VIII, IX, or X; and a major band with a molecular weight of 40,000 to 60,000 daltons on an SDS gel.
