We compared two assays for estimating the amount of active heparin bound to a catheter surface: 1) a kinetic assay based on the inactivation of thrombin by antithrombin III, and 2) thrombin uptake. Both assays were used to estimate the amount of heparin activity on a series of catheters coated with
