Coagulation control compositions suitable for use in connection with PT and/ or APTT assays are disclosed along with their methods of preparation and method s of use. Preferred coagulation controls comprise plasma and an anticoagulant having activity for enhancing the activity of antithrombin III (ATIII) or of heparin co-factor II (HCII) against thrombin or against a clotting factor selected from the group consisting of factors IXa, Xa and XIa. The anticoagulant is preferably a glycosaminoglycan such as heparin, a heparin derivative or a heparin analog. The anticoagulant is preferably combined wit h (1) an abnormal plasma (e.g. activated plasma or factor-deficient plasma) and/or (2) a primate plasma (e.g. human plasma), and a non-primate mammalian plasma (e.g. bovine plasma). In the latter case, the non-primate mammalian plasma is preferably present in the coagulation control composition in an amount of not more than about 12 % by volume, relative to total volume.</SDO AB>
