Pregnancy and breastfeeding cause complex physiological shifts in some blood markers. The size and direction of those changes vary by trimester, by marker, and from person to person, so we can't reliably adjust our lab reference ranges for them. That means some results, even if physiologically normal for your stage, may flag outside the standard range.
You can still join Do Health and complete the blood tests. Always consult your GP or midwife before making lifestyle changes.
