Episode 355: Why "Normal" Labs Don't Mean Optimal Health with Erin Kerry

In this solo episode, host Erin Kerry breaks down why "normal" on a standard lab report isn't the same thing as optimal, and why that gap might be the missing piece in your own health story. She shares her own years of hearing "everything looks fine" from doctors (including being told to simply lose weight and exercise more) while knowing in her gut that something wasn't right. Erin walks through what a standard reference range is actually built to catch (disease, not dysfunction), why fasting insulin can reveal blood sugar trouble years ahead of a diagnosis, and which markers already sitting on your basic bloodwork (like total protein, globulin, alkaline phosphatase, hemoglobin, MCV, CO2, and anion gap( can point toward gut and B-vitamin issues most providers never flag. You'll also hear why ferritin, CRP, magnesium, and B12 deserve a second look, why running labs and interpreting labs are two completely different skills, and how a borderline B12 can quietly explain the brain fog or low mood no one's connected to your bloodwork. Erin closes with a reminder that stewarding our bodies well starts with actually knowing their condition, not just glancing at a piece of paper. Whether you've been told "everything looks normal" and still don't feel like yourself, you're tired of vague answers from a seven-minute appointment, or you just want to understand your own labs better, this episode gives you a new lens to bring into your next doctor's visit.
