Plasma antithrombin III concentration in patients on regular haemodialysis treatment

Plasma concentration of antithrombin III (AT III) was measured by both immunological and functional assays before, during and after treatment with haemodialysis in 42 patients with chronic renal failure on regular long-term haemodialysis. Intravenous heparin administration during the haemodialysis session was found not to induce a consumption of the circulating AT III.
