What is normal uE3 levels in pregnancy?
Estriol is produced by the placenta from maternal substrates (cholesterol and pregnenolone). Estriol diffuses from the placenta into the maternal blood where it can be measured as unconjugated uE3. In normal pregnancies uE3 levels increase from about 4nmol/L at 15 weeks gestation to about 40nmol/L at delivery.
