Diluted rvv and then calcium chloride are added and the clotting time is measured. The test is then repeated using patient plasma and the ratio of test:normal plasma is calculated. Reagent Explanation, platelet poor Plasma, a source of coagulation factors, particularly thrombin and fibrinogen. Dilute russell's Viper venom. Typically this is diluted to give a clotting time in normal plasma of between 30-35s as this optimises sensitivity to antiphospholipid antibodies. Phospholipid, to provide a surface for thrombin generation. This should be diluted to a sufficient degree that it becomes the rate limiting step and any inhibition by a la prolongs coagulation. Calcium, to initiate coagulation, interpretation, if schaamlippen the drvvt is not prolonged then the correction test (sometimes referred to as the neutralisation test) is not indicated. Drvvt, ratio test drvvt/control drvvt, reference range: 29-42s, reference ratio:.9-1.05. Ratio test drvvt/control drvvt.05, possible la, exclude deficiencies of factors ii, v, x, fibrinogen or another non-la reviews inhibitor.

Daboia russelii or russellii - the correct spelling is a matter of great debate! Contains a potent activator of factor X which in the presence of phospholipid pl, prothrombin and calcium ions clots fibrinogen to fibrin. In individuals with a lupus anticoagulant la the antibody binds to the phospholipid inhibiting the action of the rvv and prolonging the clotting time. As the rvv directly activates factor x, the test is unaffected by deficiencies of factors xii, xi, ix or viii. The drvvt is frequently combined with a platelet neutralisation procedure to demonstrate the phospholipid specificity of the antibody. Method, pooled normal plasma is mixed with diluted pl at 37C.
