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 escalating
• Why IL-6 and TNF-α are important in biology but rarely useful as screening tests
• What ESR is good for, and why it isn't a clean longevity marker
• How SHBG and albumin change what your testosterone result really means
• When it makes sense to go further, with LH, FSH, prolactin and estradiol
