ABSTRACT
To compare cervical fibronectin as predictive marker for success of induction of labor compared with the traditionally was Bishop Score. Setting: Kasr EL-Aini Hospital. Design: A prospective controlled trial. Participants and 100 fullterm singleton pregnant women undergoing labor induction due to postdatism were examined to determine Bischop score and cervicovaginal fibronectin was assessed using fast reacting membrane immunoassay. There was a highly significant difference in the success of labor induction between women with positive and negative fibronectin test results. P<0.001. Fibronectin compared to Bishop Score has Sensitivity of 64.5%, Specificity of 44.8%, Positive predictive value of 78.9%, Negative predictive value of 54.2%, accuracy = 73%. Fetal fibronectin is a simple, easy and sensitive test for prediction of successful labor induction in women with prolonged pregnancy. If fetal fibronectin test in negative, induction of labor should be considered in women only with high Bishop Score.
