Objectives: To evaluate the role of admission non stress test as a screening method in low and high risk pregnancies and to assess the perinatal outcome. Methods: In this study 326 women with singleton term pregnancies admitted in established labour were subjected to admission stress test (AST). These women were classified into three subgroups according to result of AST: Reactive, Equivocal and Non reactive group. Perinatal outcome was evaluated in all the groups along with sensitivity, specificity, positive and negative predictive values of the test. Results: caesarean and instrumental delivery rates for fetal distress were higher in non-reactive and equivocal group than in the reactive group. Perinatal morbidity in reactive, equivocal and non reactive groups was 4.8%, 28.94% and 55.92% respectively. Sensitivity and specificity of the test in this study were 63.63% and 93.33% respectively. Positive predictive value was 55.26%, while negative predictive value was 95.2%. Conclusion: Admission stress test can be used as a primary screening technique to pick up high risk fetuses and thus timely intervention can reduce perinatal morbidity.
