Blood coagulation factor XIII (FXIII) plays an important role in the final stage of the blood coagulation process. Thrombelastography (TEG) enables global assessment of the hemostatic function. The present study tested for the first time the specificity and sensitivity of the rotation thrombelastography (ROTEG: rotation thrombelastography) method for the influence of FXIII and the FXIIIVal34Leu polymorphism on thrombelastograms measured in citrated plasma. Three thrombelastographic parameters were determined in (a) citrated pool plasma, (b) FXIII-deficient plasma, (c) different mixtures of both, and (d) in 60 plasma samples genotyped for FXIIIVal34Leu. Thrombelastograms from FXIII-deficient plasma were significantly smaller than those from pool plasma (8 mm vs. 20.9 mm). Increasing amounts of pool plasma added to FXIII-deficient plasma led to an increase in maximum clot firmness (MCF). FXIIIVal34Leu showed an influence on clot formation time (CFT) values, which decreased with increasing number of Leu alleles. The difference between the wild type and the homozygote mutant genotype was statistically significant (median 185.3 vs. 86.0 s, P=.031). ROTEG is a simple but effective method for the investigation of FXIII function in plasma. The ROTEG method has shown to be not only specific for the FXIII influence, as effects exclusively dependent on FXIII could be observed, but also sensitive, as already smallest amounts of FXIII could be detected. Additionally, the impact of a common genetic polymorphism on ROTEG could be shown for the first time.
