Abstract
Two-year-and-4-month-old boy with congenital afibrinogenemia was investigated mainly in regard to the microdetermination of fibrinogen in plasma.
Although the determination of the trace of fibrinogen was unsuccesful by the method of blood coagulation, electrophoresis or immunoelectrophoresis, by means of the hemagglutination inhibition test. The amount of plasma fibrinogen in this case was measured to be 4.2 mg/100 ml.
It may be mentioned that the hemagglutination inhibition test is one of the most hopeful method to detect very small amount of fibrinogen in case of congenital afibrinogenemia.
