ABSTRACT
For the detection of aPL that prolong phospholipid-dependent clotting assays (lupus anticoagulant, LA) clotting time prolongation assays are used, in which prolongation of clotting is not corrected with normal plasma, but with the addition of phospholipids. These tests include the activated partial thromboplastin time (aPTT), the diluted Russell’s viper venom time (dRVVT), and the kaolin clotting time (KCT).2
