About the Study
What is the BioBAYB2 Study?
BioBAYB2 stands for Biological Rhythms Before & After Your Birth Study. This groundbreaking research study aims to improve the accuracy of predicting when labor will begin.
The 40-week estimated due date is only an average estimate of how long pregnancy might last—it doesn't offer a personalized prediction of when labor will actually begin. Improved and advanced prediction could improve care planning and outcomes for both mothers and babies, especially for issues like preterm birth.
