[Express method for determining blood coagulation time]

The author established that coagulation time of capillary blood is the shorter, the longer time has elapsed from the time of pricking till the moment of blood withdrawal. That shortening of time is considerably less if the small wound made it deeper and wider. The first escaping drop coagulates most slowly. The author established that the investigation with it gives identical data with the venous blood investigation not only in healthy but also in patients with hemophilia and those treated with heparin or indirect anticoagulants. Based on those data, the author elaborated and recommended a method with capillary blood, providing identical data as those with the venous blood investigations.
