The study is aimed at developing a novel, low-cost test for pre-term birth (PTB). The proposal is intended to test and validate the low-cost salivary progesterone as a point-of-care (POC) test for detecting risk of PTBs in rural community settings of India. Offering non-invasive sampling of biological fluid that is easy to collect, the study allows validation of saliva from a large cohort of pregnant women residing in low-resource community settings. It is planned to obtain single saliva sample from each participant and determine its predictive characteristics against gestation at delivery and other obstetrics and neonatal outcomes.
