To compare the serum pregnancy specific glycoprotein 1 values of women with preeclampsia with the values of healthy pregnant women. A total of 90 pregnant women, whom were recruited during their antenatal care visits to the obstetrical department in Hospital, were included. They were divided into two groups: 45 women with diagnosis of preeclampsia and 45 controls who were the women with healthy pregnancy. Blood samples were collected from both groups and the measurement of pregnancy specific glycoprotein 1 was done using an enzyme immunometric assay. The groups of preeclampsia pregnant women had markedly lower pregnancy specific glycoprotein 1 than the women with the uneventful pregnancies (9.8±3.8 vs 14.3±6.0 ng/ml; p value <0.001). Pregnancy specific glycoprotein 1 can significantly predict preeclampsia (P value <0.001) with an odds ratio of 0.839 and 95% confidence interval of 0.763 – 0.924. By application of receiver operating characteristic curve analysis, it was observed that the cut-off value of pregnancy specific glycoprotien1 for predicting preeclampsia was 10.4 ng/ml with 77% sensitivity and 60% specificity, the area under the curve 0.728 with 95% confidence interval between 0.622 and 0.835, P value < 0.001. Pregnancies complicated by preeclampsia are associated with decreased maternal serum level of pregnancy specific glycoprotien. This abnormally decreased levels of might be a reflection of stressed or dysfunctional syncytiotrophoblasts, which is related to the pathogenesis of this placental disorder.
