Background: Thrombophilia complicates the pregnancy by interfering the physiology of utero-placental circulation which in turn leads to IUGR, IUD, PIH, RPL, abruption placentae. This study is to find out the prevalence and significance of different thrombophilia markers in cases of adverse pregnancy outcome in eastern part of Uttar Pradesh, India.Methods: 54 antenatal women are selected from the cases presented with or previous history of PIH, IUGR, IUD, Abruption or early/late abortion. A thorough family history, history of risk factors, clinical examination were noted. Platelet count, prothrombin time(PT), activated partial thromboplastin time (APTT), plasma fibrinogen, factor-VIII assay, LA, ACLA, protein- C, protein- S, TORCH, thyroid profile, blood sugar, USG is done in all patients at the time of first registration. 50 antenatal females without any bad obstetric history was taken as controls.Results: Among 54 cases, 64.8% cases were positive for thrombophilia markers, whereas 6% control had presence of thrombophilia markers. 6.5% thrombophilia positive cases had ≥3 markers present and had ≥2 manifestations of adverse pregnancy outcome in 100% cases. Prevalence of different thrombophilia markers are studied in individual case and association to various outcomes were noted.Conclusions: There was high prevalence of thrombophilia markers in the cases with adverse pregnancy outcome. As treatment was found significantly effective in literature, screening of these markers should be done in patients with bad obstetric history
