The Longevity Lab MD Podcast 🎙️

Some longevity panels measure everything: IL-6, TNF-alpha, ESR, and dozens more. So why do I measure just one inflammation marker?In this episode I explain, in plain English, what inflammation really is, what each of these blood tests measures, and why more data isn't the same as more information. Then I answer a second question I'm asked constantly: if you test testosterone and SHBG, what else should you be checking?You'll learn:Why hs-CRP is the inflammation marker worth measuring, and why you repeat it before escalatingWhy IL-6 and TNF-α are important in biology but rarely useful as screening testsWhat ESR is good for, and why it isn't a clean longevity markerHow SHBG and albumin change what your testosterone result really meansWhen it makes sense to go further, with LH, FSH, prolactin and estradiolChapters (0:00) Why we don't test everything (1:02) Inflammation 101 (2:45) hs-CRP: the one we keep (4:36) IL-6 & TNF-α (7:20) ESR (8:36) The verdict (9:24) The testosterone question (12:07) A two-stage approach (14:04) Better medicineWatch the animated version on YouTube: https://youtu.be/IGByagnMGkk?si=t1W0fel73EPe1NPRSources: Pearson et al., Circulation 2003 · Ridker, NEJM 2002 · Mayo Clinic Laboratories · Vermeulen et al., JCEM 1999 · Endocrine Society 2018 · AUA 2018.Educational content only, not medical advice.
