In the US you can order many blood panels yourself, without a physician visit, through direct-to-consumer lab services. This guide walks through your options and how to read what comes back.
What this guide will cover
- Direct-to-consumer labs vs. going through a doctor
- Which panels to order for a biological-age baseline
- How to read a lab requisition and reference ranges
- Getting a copy of your own results
This guide is being expanded. In the meantime, the PhenoAge calculator works with any standard panel, and What drives your PhenoAge explains which markers matter most.
