Levels of fibrinogen, plasminogen, antithrombin III, α<sub>2</sub>-plasmin inhibitor and α<sub>2</sub>-macroglobulin in plasma were determined using single radial immunodiff usion method in an old people's home in 1979, 1981 and 1982. Comparison of results of these parameters in the same subjects between in 1981 and 1982 was possible in 67 subjects. Comparison between in 1979 and 1981 was done in 61 subjects. Results of coagulation analysis in 1979 and 1982 were compared in 49 subjects.<br>Generally, concentrations of plasminogen, antithrombin III and α<sub>2</sub>-plasmin inhibitor in plasma were higher in women than in men. There were statistically significant correlations between all the parameters determined at intervals of 1, 2 and 3 years in the same subjects. The coefficients of correlation in each parameter at intervals of 1 to 3 years were as follows: +0.45-+0.57 in fibrinogen, +0.69-+0.81 in plasminogen, +0.55-+0.81 in antithrombin III, +0.46-+0.64 in α<sub>2</sub>-plasmin inhibitor and +0.91-+0.93 in alpha;<sub>2</sub>-macroglobulin. From these results, it is concluded that old women are generally less thrombotic than old men and that there is some “individuality” in patterns of the parameters affecting blood coagulation and fibrinolysis in the elderly. The significance of the “individuality” upon prognosis of the elderly was discussed.
