Abstract OBJECTIVE: To assess the diagnostic accuracy of vaginal fetal fibronectin (fFN) sampling for predicting preterm birth in asymptomatic women carrying triplet gestations. METHODS: An historical cohort of patients carrying triplet gestations between 1998 and 2010 was identified from a single practice by chart review. All patients were screened with fFN testing at 2-3 week intervals from 22 weeks to 32 weeks of gestation. Outcomes evaluated were spontaneous preterm birth prior to 28, 30, and 32 weeks' gestation and delivery within 2 and 3 weeks of testing. RESULTS: There were 56 pregnancies that met criteria for inclusion. For delivery prior to 30 weeks' gestation, the test had a sensitivity of 75%, a specificity of 85.4%, a positive predictive value of 46.2%, a negative predictive value of 95.3%, positive likelihood ratio of 5.13, and a negative likelihood ratio of 0.29 (p<0.0001). For delivery within 3 weeks of a single fFN assessment, the test had a sensitivity of 53.3%, a specificity of 95.8%, a positive predictive value of 53.3%, a negative predictive value of 95.8%, positive likelihood ratio of 12.7 and negative likelihood ratio of 0.48 (p<0.0001). CONCLUSION: Fetal fibronectin testing provides moderate to high prediction of spontaneous preterm birth in triplet gestations.
