Hemoglobin A1c with Calculated Mean Plasma Glucose (MPG)

Hemoglobin A1c with Calculated Mean Plasma Glucose (MPG) - The American Diabetes Association (ADA) suggests getting this test twice a year if your blood sugar is stable, and every three months if it's not well controlled. The test also includes a calculation of the Mean Plasma Glucose (MPG), which estimates the average blood glucose level derived from the HbA1c result. This calculated MPG helps in understanding daily glucose fluctuations and tailoring diabetes management plans accordingly. High levels indicate poor blood sugar control, suggesting a need for adjustments in treatment.

Stephanie Strudley, CNS, is a functional medicine nutritionist and the founder of Upstream Wellness. She helps driven, health-conscious adults who've done "everything right" and still don't feel like themselves — connecting the dots between symptoms, labs, and lifestyle to uncover what's actually going on. Her approach is shaped by an unconventional path: a background in ecology and systems biology, and her own experience navigating serious, unresolved health challenges before finding root-cause care herself. She doesn't believe in one-size-fits-all protocols or quick fixes — she believes health is more like solving a puzzle than following a formula, and her role is to help clients ask better questions, interpret their own data, and build a plan that fits their unique biology and life.
