What You Need to Know About Blood Work in Preconception, Pregnancy, and Postpartum

with podcast guest

MaryAnn Marks & Sara Russell


MaryAnn Marks & Sara Russell have worked with hundreds of fertility clients in their combined 19 years of nutrition experience. They teamed up for their current project—What You Never Learned About Blood Work in Preconception, Pregnancy, & Postpartum—after discovering major gaps in the now widely used functional blood chemistry ranges that so many naturopathic and functional medicine doctors and practitioners use in their practices.

In this episode, we talk about the specific blood tests that are helpful in preconception, pregnancy and postpartum, the need for pregnancy-specific ranges for thyroid hormones, discrepancies in pregnancy and postpartum ranges that other clinicians may overlook, and so much more!


  • Sara and MaryAnn’s backgrounds and how they teamed up to educate practitioners about blood work
  • Recognizing that the problems with the allopathic medical system go deeper than individual doctors
  • Where lab reference ranges typically come from, and why we recommend using bio-individual optimal ranges instead
  • Why we need to use adjusted optimal ranges for preconception, pregnancy, postpartum, and during lactation
  • Preconception testing recommendations for males and females
  • Expected changes in blood test results during pregnancy
  • What you need to know about thyroid and blood sugar testing around pregnancy
  • Postpartum lab testing and the need for increased awareness of postpartum depression and anxiety symptoms
  • postpartum depression and anxiety symptoms
  • The connection between pelvic floor health and postpartum recovery
  • Inflammation and oxidative stress in the postpartum period
  • How MaryAnn and Sara’s work can empower fertility-focused practitioners to help improve outcomes
