Thromboelastography results of 13 group A healthy donors. Following normal clot kinetic parameters baseline values, 300 μL of kaolin-citrated blood was mixed with 40 μL of normal saline, A plasma, or O plasma with anti-A titer of 1:128, or 1:1024.

MA, maximum amplitude; MA30, amplitude at 30 minutes; CI, coagulation index.

^{^}Data are presented as mean ± standard deviation.

^*Values are statistically significant (p < 0.05) in comparison to the A plasma values.
