Abstract
The invention provides a one-stage method of measuring antithrombin (AT) activity in a sample. In the method, a diluted sample is mixed with AT-deficient plasma containing intrinsic coagulation enzymes, an AT augmenting compound such as heparin, a phospholipid and an activator of the contact phase of the intrinsic coagulation pathway. Following addition of calcium ions, coagulation time is measured and compared to a reference standard to determine the level of AT activity in the sample.
