Fibrin Degradation Products in Sera of Women with Normal Menstruation and Menorrhagia

Serum concentrations of fibrin degradation products were found to be higher during menstruation than in the intermenstrual phase. Higher concentrations were present in cases of menorrhagia as compared with healthy women and women with various gynaecological disorders but with normal menstrual function. Higher serum concentrations of fibrin degradation products in cases of menorrhagia may indicate increased local fibrinolytic activity in the uterus.
