Changes in Bleeding and Clotting During the Menstrual Cycle

NCT00480545 · Status: WITHDRAWN · Type: OBSERVATIONAL

Last updated 2014-12-05

No results posted yet for this study

Summary

Indirect evidence suggests that hormonal fluctuations during the menstrual cycle also affect the bleeding and clotting system. This study looks at two sensitive laboratory tests at four time points during the menstrual cycle to determine if there is a natural variation in coagulation and platelet function. Laboratory tests in healthy subjects will be compared to women with von Willebrand's disorder type 1, a bleeding disorder. In the future, these laboratory tests may help in the diagnosis of bleeding and clotting disorders and to design treatments for women with abnormal menstrual bleeding.
