Trypsin clotting time (K-test) in hemophilia A and in hemophilia B1.
In investigations made in 32 patients with haemophilia A and 28 patients with haemophilia B the possibility of utilizing the trypsin clotting time (K-test) was tested in diagnosing both diseases. 23 plasmas of healthy test persons were used as controls and revealed a mean value of the K-test amounting to 24.52 +/- 0.75 seconds. With a mean value amounting to 30.025 +/- 2.88 seconds the K-test was clearly and from a statistical point of view significantly prolonged in hemophilia B contrary to hemophilia A with a slight prolongation amounting to 26.95 +/- 2.03 seconds. Possible causes for the response of the trypsin clotting tie are discussed.
