RESUMEN
Thrombophilia is characterized by increasing blood coagulability. It causes preeclampsia and repeated abortions. This study was done to determine the corrolation of coagulation factors deficiency with preeclampsia. This case-control study was carried out on 142 pregnant women with preeclampsia as caess and 142 pregnant women without preeclampsia as controls. Coagulation factors including Prs, prc, and anti-thrombin-3 were measured using ELISA and chromogenic methods. Prs deficiency was found in 2 [1.4%] and 6 [4.2%] of cases and controls, respectively. This difference was not significant. Prc and anti-thrombin- 3 deficiencies was not found in cases and controls. There is not any relation between deficiencies of coagulation factors with preeclampsia
