Summary An enzyme-linked immunosorbent assay (ELISA) was developed for the determination of thrombin-antithrombin III complex (TAT) in human plasma. The test system follows the sandwich principle and uses two different antibodies directed against human thrombin and human antithrombin III, respectively. The antibodies bind selectively to the corresponding antigen moieties of TAT. The assay was calibrated with definite concentrations of preformed purified TAT added to TAT-poor plasma. The lower limit of sensitivity of the assay was 0.5 μg/1. Mean coefficients of variation of 4.2% (intraassay) and 3.5% (interassay) were found for TAT concentrations between 2 and 60 μg/1. A reference range from 0.85 to 3.2 μg/1 was calculated from TAT concentration in plasma samples from 88 healthy donors (mean value ± SD: 1.45 ± 0.4 μg/I). In plasma samples from patients with pulmonary embolism (n = 17), TAT concentrations between 3 and 25 μg/1 were measured. In 15 patients with deep vein thrombosis, TAT was found up to 3 to 25 μg/1. From these data we conclude that measurement of TAT can be a sensitive parameter for specific detection of a latent activation of the clotting pathway.
