ABSTRACT:
In order to determine lupus anticoagulant (LA) antibodies in blood, plasma or tissue samples by means of the inhibitory effect of these antibodies on the neutralizing effect of protein C on the blood coagulation system, a defined amount of activated protein C is added to the sample, after incubation the remaining amount of a physiological substrate of protein C or protein S activity in the sample is determined according to known methods and the amount of LA antibodies present is calculated by comparison with a standard containing no LA antibodies. The method according to the present invention can be used to diagnose a predisposition to thrombotic events or disease-dependent risk of thrombosis as well as to monitor a therapy.
