Abstract:
In a longitudinal study involving 100 Singaporean women, results indicate that the acceptors persist in having a possibly increased predisposition to thrombosis, as evidenced by a significant increase in platelet count and aggregability. Furthermore, the shortened prothrombin time and activated partial thromboplastin time, together with changes in vitamin K factors, still indicate the possible enhanced potential for hypercoagulation.
