Why this matters
Inflammation is the fire that ages you.
Systemic chronic inflammation is associated with many age-related conditions, from cardiovascular disease to cognitive decline. iAge® measures it in a single score built from five inflammatory proteins.

Edifice Health is the official XPRIZE Testing Partner for XPRIZE Healthspan. Inflammation endpoints for your study.
What exactly do I learn?
You receive your iAge score (inflammatory age vs chronological age), a breakdown of your biomarkers and their concentrations, how they compare with the median for your age bracket, and personalized recommendations. Retest to track changes over time.
Is this diagnostic?
The iAge Test is an informational assessment tool that measures key proteins. It provides insights into your inflammatory status and aging trajectory based on other individuals in your age bracket but should not be used to diagnose, treat, or prevent any disease. Always consult with a healthcare provider for medical advice.
Is it accurate?
Yes. Samples are analyzed in a CLIA-certified laboratory. iAge® was developed from peer-reviewed research at Stanford, and a 2026 Nature Medicine paper describes it as validated in independent cohorts.
Is it painful?
No. The test uses a simple at-home upper arm capillary collection method (similar to a finger prick) that takes about 5 minutes. Most people experience minimal discomfort.
How long does it take?
The collection takes about 5 minutes at home. After you mail back your sample, results typically arrive in about 2 weeks. Please allow up to 30 business days.
How often should I test?
Many people test quarterly (every 3 months) to track changes and the impact of lifestyle modifications. However, the frequency depends on your personal health goals. Our Quarterly Optimization bundle is designed for those who want regular tracking.
