About This Site

This is an independent guide to biomarker testing services. Providers cannot pay to be listed or ranked higher, and the comparisons come from ordering and reviewing these services firsthand.

Thanks to the influence of Peter Attia, Andrew Huberman, and other high-profile figures in the health and wellness space, blood testing has become increasingly popular for those looking to optimize their health and longevity.

When I began researching online blood testing providers, I was overwhelmed by the number of options and frustrated by the lack of clear, side-by-side comparisons. Each provider had its own marketing claims, but it was hard to tell what tests were actually included, how they differed, and which offered the best value.

Our Approach

This site exists to solve that problem. I've personally tested Function Health, Quest, and Empirical Health, and reviewed Superpower, GoodLabs, VitalsVault, and Inside Tracker in detail. The result is a set of objective, side-by-side comparisons of blood test packages so you can make informed decisions about your health monitoring.

Providers cannot pay to be included or rank higher on this site. Our comparisons are based solely on the biomarkers offered, pricing, features, and overall value.

What We Compare

• Biomarkers tested: The specific health markers included in each package
• Pricing: Cost per test and frequency options
• Features: Mobile apps, web dashboards, doctor reviews, and other services
