Trend plot for mean percentage changes in coagulation and anticoagulant factor activities in sample after storage. Trend plot for mean percentage changes in FII, FV, FVII, FX, FVIII, FIX, FXI, FXII, FXIII, AT, PC, and free PS activities in samples after storage for 2, 3, 4, and 5 h at room temperature (18 to 25 °C) (a); 2, 3, 4, and 5 h under refrigeration (2 to 8 °C) (b); and 1, 2, 3, and 4 months at frozen (− 15 to − 25 °C) (c), compared with the baseline results. The two dotted lines in the figures represent ± 15%. FII factor II, FV factor V, FVII factor VII, FX factor X, FVIII factor VIII, FIX factor IX, FXI factor XI, FXII factor XII, FXIII factor XIII, AT antithrombin, PC protein C, Free PS free protein S.
