What biomarker labs measure, why panel size is a poor proxy for quality, and how to build a blood panel you can reason about over time.

A working list of blood, molecular, and continuous biomarkers worth tracking on yourself, with the biological-variation math that tells you when a change is real and when it is noise.

Which vitamin and mineral analytes are worth measuring, which ones are nearly uninterpretable in serum, and how preanalytical handling and inflammation decide whether your panel means anything.

A working guide to the five standard inflammation markers, from hs-CRP to IL-6. Covers what each tracks, noise in a single value and sample handling.

A fitness or gym blood panel is only interpretable if you control what you did in the 72 hours before the draw. Here is the panel we would order, the confounders that corrupt it, and how to analyze the results over time.

The 56-biomarker performance panels sold as a full-body MOT test the wrong thing in the wrong way. Here is the panel we would order, how to control preanalytics, and how many repeats you need before a number means anything.

A technical guide to choosing and using a biomarker testing service: what analytes are worth measuring, what the analytical error looks like, how to store and version the results, and where a clinician has to be involved.

There is no single 'Huberman blood test.' Here is the panel that gets discussed on the podcast, which markers carry real signal, and how to get the data in a form you can analyze yourself.
