AIM: The aim of this study was to compare the accuracy of placental α-microglobulin-1 (PAMG-1), insulin-like growth factor binding protein-1 (IGFBP-1) and nitrazine test to diagnose premature rupture of membranes. MATERIAL AND METHODS: A total of 120 pregnant women between 11 and 42 weeks with signs/symptoms of membrane rupture were eligible for our study. These women were evaluated with the PAMG-1, IGFBP-1, and nitrazine tests. RESULTS: In the 120 women, the sensitivity, specificity, positive predictive value, and negative predictive value of PAMG-1, IGFBP-1 and nitrazine test were 100%, 100%, 100%, and 100%, 93.33%, 98.89%, 96.55% and 97.80%, and 93.33%, 94.44%, 84.85%, and 97.7%, respectively. In a comparison of the PAMG-1 test and the nitrazine test, positive coincidence rate was 84.85%, negative coincidence rate was 97.70%, total coincidence rate was 94.17%, and kappa value was 0.85. In a comparison of the PAMG-1 test and the IGFBP-1 test, the positive coincidence rate, negative coincidence rate and total coincidence rate were 96.55%, 97.80%, and 97.50%, and kappa value was 0.93. CONCLUSION: PAMG-1 assay was the most accurate method to diagnose premature rupture of membranes with the highest sensitivity, specificity, positive predictive value and negative predictive value.
