Pregnant women (n = 78) with a single pregnancy between 24 and 34 weeks of gestation, presented with labor pain, and had regular uterine contractions (threatened preterm labor – TPL) were included. Patients delivered within the first week after TPL were included in group 1 (n = 40) and who delivered after in group 2 (n = 38). Two groups were investigated for NLR and PLR values.Results: The median cervical length among women who gave birth within a week was significantly lower (24.5 versus 30.0 p 5 for NLR (sensitivity: 90%, specificity: 92.1%), > 139 for PLR (sensitivity: 97.5%, specificity: 100%).Conclusion: NLR and PLR values predict spontaneous preterm birth with high sensitivity and specificity. By predicting preterm birth, the pregnancy process can be managed sensitively and smoothly.Keywords: neutrophil-lymphocyte ratio, NLR, platelet-lymphocyte ratio, PLR, preterm birth, prediction
