Abstract

We examined 14 carriers of haemophilia A with the "Haemorrhagometer". The cold tolerance test (at 17 degrees C) revealed that 9 out of 10 proven and 3 out of 4 probable carriers had a pathologically prolonged bleeding time. Accordingly blood loss was pathologically elevated in 9 out of 10 proven and 2 out of 4 probable carriers. At room temperature the difference between normal control persons and carriers of haemophilia A was not as pronounced. 5 of 8 proven and 3 of 4 probable carriers showed pathologically elevated bleeding intensity, only 1 of 8 proven and none of 4 probable carriers showed abnormally prolonged bleeding time. Haemorrhagometry at 17 degrees C (cold tolerance test) may be helpful to ascertain whether or not a woman is a carrier of haemophilia A.

Blood Clotting Disorders

Thrombophilia includes conditions with increased tendency for excessive blood clotting. Blood clotting occurs when the body has insufficient amounts of specialized proteins that make blood clot and stop bleeding. Here is the latest research on blood clotting disorders.
