An exploratory study to be published in BJOG: An International Journal of Obstetrics and Gynaecology, has shown that women going into early preterm labour (before 34 weeks gestation) have low-levels of progesterone in their saliva as early as 24 weeks, and that moreover, these levels fail to rise during pregnancy in the normal way. This offers the possibility of developing a simple, non-invasive test to identify women at increased risk of delivering early.
