Know Your Labs is a weekly show from Nurses Know Life, made for moms who are tired of being told their labs look 'normal' while they still feel exhausted, foggy, and not like themselves. Each short episode breaks down one lab topic or supplement in plain language: what the tests can tell you, what they can't, and what a reasonable next step looks like — from the markers that matter before and after pregnancy to the hormone shifts of your late 30s and 40s. No fear tactics, no miracle claims. Just honest, nurse-reviewed education. Every topic is reviewed by Nicole Kasch, MSN, RN, CFMP, founder of Nurses Know Life.
New episodes every Monday.

Your Blood Sugar Was Normal. What About Your Insulin?
Your glucose and A1c came back normal, but that may only be half the story. Maya breaks down what fasting insulin adds to the picture, how your body can keep blood sugar looking fine for years simply by working harder, and the honest next step if insulin was never checked.

Your TSH Was Normal. So Why Do You Still Feel Like This?
Maya from the Nurses Know Life team explains thyroid labs beyond TSH: what free T4 tells you about supply, why free T3 is the active form, what reverse T3 adds as context, and how thyroid antibodies reveal the autoimmune piece. A normal TSH answers one question, not every question. Explore the Thyroid Panel Comprehensive single-marker test and the Thyroid Wellness Insights Lab Journey at nursesknowlife.com/wellness-shop (http://nursesknowlife.com/wellness-shop), and read the companion article at nursesknowlife.com/thyroid-labs-explained (http://nursesknowlife.com/thyroid-labs-explained).

What If It Isn't Your Hormones — It's Inflammation?
Maya from the Nurses Know Life team explains hs-CRP, the inflammation blood test most women have never heard of — what it measures, what the numbers mean, and why it can say something your cholesterol panel never will. Curious about your own number? Find the hs-CRP single-marker test and the Inflammation & Nutrient Insights Lab Journey at nursesknowlife.com/wellness-shop (http://nursesknowlife.com/wellness-shop).

Your FSH Was Normal. So Why Does Everything Still Feel Like It's Changing?
Your doctor said your hormone levels look normal — so why do your periods keep changing and you keep waking up at 3 a.m.? Maya explains what perimenopause labs (FSH, estradiol, TSH) actually measure, why one test can mislead in either direction, and why the trend matters more than the number. If your own lab results feel like a mystery, Nicole offers individual lab results reviews — details at nursesknowlife.com/wellness-shop (http://nursesknowlife.com/wellness-shop)

Everyone Takes Vitamin D. Almost No One Tests First
Vitamin D is the supplement everyone takes and almost no one tests. This bonus episode breaks down the 25-hydroxyvitamin D test: what it actually measures, why experts disagree on the "low" cutoff, and why the same person can get a different number on different lab machines. Plus: why the dose starts with a test. Explore Lab Journeys and professional-grade supplements at nursesknowlife.com/wellness-shop (http://nursesknowlife.com/wellness-shop).

Your Labs Were Normal, But Nobody Checked Your Ferritin
Your labs came back "normal" — so why are you still exhausted? This episode explains the difference between a standard CBC and ferritin, why low iron stores can exist long before anemia shows up, and two other markers worth knowing: B12 and vitamin D. Plus, why testing first beats guessing with supplements. Reviewed by Nicole Kasch, MSN, RN, CFMP.
