RESUMEN

INTRODUCTION: During the fluid phase of hemostasis, fibrinogen is converted into fibrin, but other hemostatic factors are required. Reference values of hemostatic factors are established by manufacturers producing reagents using individuals with a specific genetic background. OBJECTIVE: To establish reference values for hemostatic factors in the Mexican indigenous and Mestizo populations. MATERIAL AND METHODS: We carried out a cross-sectional, descriptive study of healthy adult Mexicans. Clotting activity was evaluated using coagulometric assays. Blood donors were informed about the nature of the study and informed consent was obtained prior to blood being drawn. The protocol was approved by the Ethics Committee of our institution. RESULTS: One hundred and twenty samples were assayed (60 females and 60 males). Fibrinogen was higher in mestizos and in females. Reference values for factor XII ranged from 40-170% in indigenous subjects and from 36-159% in mestizos. Factor VIII ranged from 57-160% in indigenous subjects and from 51-209% in mestizo subjects. Reference values for the other hemostatic factors were also clearly different from the commercial reference values. Reference values for hemostatic factors in the Mexican population are different from traditionally used commercial reference values. There were significant differences between indigenous and mestizo Mexicans in the concentration of hemostatic factors with a tendency among mestizos to have higher factor concentrations. Low levels of plasma factor XII are frequent and perhaps may represent a risk factor for thrombotic events. Using these reference values may individualize the reposition of factors in Mexican hemophiliac patients.
