Coagulation factor activity (fibrinogen, VII, VIII and IX), coagulation inhibitor activity (antithrombin, protein C, protein S), and coagulation activation markers (prothrombin fragment F1, 2; thrombin–antithrombin complexes) were measured in 747 men and 817 women aged 25–74 years, randomly sampled from the north Glasgow population in the Third MONICA Survey. Significant effects of age, sex, menopause and hormone use were observed and specific reference ranges are presented to illustrate these effects. Significant correlations were observed between several coagulation factors and inhibitors. Increased levels of factors VII, VIII and IX and decreased levels of protein C were associated with increased coagulation activation. In general, increases in coagulation factors with age were greater than increases in coagulation inhibitors, especially in men; this imbalance may favour increased coagulation activation and hence increased thrombotic risk with age.
