What Testing is Recommended for Pregnant and Breastfeeding Women?

Maternal lead passes easily across the placenta to the developing fetus. Blood lead levels are associated with adverse maternal and fetal health outcomes. Prenatal lead exposure affects children’s neurodevelopment, placing them at increased risk for developmental delay, reduced IQ, and behavioral problems. Lead is excreted in breast milk and may be a significant source of exposure for some breastfeeding infants. CDC and the American College of Obstetricians and Gynecologists recommend evaluating all pregnant and breastfeeding women for risk for lead exposure and performing blood lead testing if risks are identified (see Additional Resources section).
