Episode 143: Why Most Pregnancy Lab Work Falls Short (And What Women Actually Need)

Most pregnancy lab work is designed for the average non-pregnant person, not the rapidly changing physiology of pregnancy. In this episode, we break down why standard lab testing often falls short during pregnancy and postpartum, and what that means for thyroid function, nutrient status, metabolism, and immune health. You’ll learn how trimester-specific lab ranges impact interpretation, which critical markers are commonly missed, and why relying on standard reference ranges can overlook meaningful changes. We also cover the role of thyroid health in fertility, pregnancy, and fetal development, how autoimmunity influences pregnancy and postpartum outcomes, and why postpartum lab testing is essential for recovery, hormone balance, and long-term health of both mom and baby.
