Salivary Estriol Level Evaluation in Diagnosis of Pre-Term Labor

The purpose of this study was to evaluting of salivary estriollevel in hospitalized women with diagnosis of preterm labor.

This was an analytic observationat investigation. During this study, salivary estriol specimens were obtained from 43 women at 24 to 34 weeks 6 days gestational age with symptoms of preterm lab or .We compared maternal salivary estriollevels between case group with preterm labor.

This study showed that the mean of salivary estriollevels in 31, 32, 33, 34 weeks in case group were higher than control group. Reciever-operator curve showed that exceeding a 0.1875 ng/ml salivary estriollevel was associated with occurrence of preterm delivery.

This study showed a wide range of salivary estriollevels in different pregnants and this distinction became more extent with lengthening gestation. Detection of increased estriollevel may be clinically helpful in defining at risk woman for preterm birth.
