Non-invasive sensor aims for rapid, highly specific detection of salivary oxytocin in perinatal women

Accurate and timely monitoring of oxytocin levels is crucial, especially in perinatal health, where it plays a vital role in labor induction and postpartum bonding. Current methods for measuring oxytocin often involve invasive blood draws or require laboratory processing, which can be slow and inconvenient. This limits real-time assessment and optimization of oxytocin administration. A non-invasive, rapid detection method could significantly improve clinical management and research into oxytocin's effects on mother and child.

Researchers designed a study to develop and validate a non-invasive sensor for salivary oxytocin. The study will enroll 25 participants across two cohorts: 20 in an induction of labor cohort and 5 in a Cesarean delivery cohort. Participants will receive oxytocin as per standard clinical protocols at Lucile Packard Children's Hospital, with no changes due to study enrollment. The protocol involves only sampling of saliva and blood. The primary endpoints are the sensor's accuracy in reporting oxytocin levels in saliva compared to standard reference methods and its ability to yield rapid (<20 minutes) results with minimal discomfort.

This study outlines the development of a novel research instrument, focusing on its potential to accurately and rapidly detect oxytocin. The primary hypotheses guiding this development are twofold. First, the sensor is hypothesized to accurately report oxytocin levels in saliva samples when compared against established standard reference methods. Second, the sensor is expected to deliver rapid results, specifically within <20 minutes, while ensuring minimal discomfort for subjects. The overarching goal is to optimize the administration of exogenous oxytocin and foster a deeper understanding of its blood concentration and subsequent effects on both mother and child. This foundational work aims to pave the way for more efficient and patient-friendly monitoring of this critical hormone. The study aims to demonstrate:

The sensor will accurately report the levels of oxytocin in saliva samples as compared with standard reference methods.
