My At-Home Inflammation Test with COR1: What I Learned and What’s Next

For over a decade, I’ve battled persistent inflammation. Despite numerous tests, symptoms that align with rheumatoid arthritis (RA) have never been confirmed in my bloodwork. Like many others with seronegative RA or undiagnosed autoimmune conditions, I’ve often felt stuck—especially when medications intended to help end up making me feel worse after every injection.

Before starting yet another RA medication that causes side effects I can barely tolerate, I decided to try a different approach. I ordered the COR1 by CorHealth, the first at-home device that tracks your inflammation levels using ESR (erythrocyte sedimentation rate).

It took a few tries to get the sample right—too much blood or bubbles and it won’t read—but once I figured it out, the results confirmed what I already knew: my inflammation is high.

My ESR level came back at 26 mm/hr, which is considered out of range. The COR1 device also gave me a “COR Age” that was 20 years older than my actual age—something I definitely want to improve.

The most valuable part? The personalized recommendations based on my results:

• Diet: Drink tart cherry juice—users with moderate ESR saw small but noticeable improvements.
• Exercise: Aim for 150–200 minutes of aerobic exercise weekly (think walking, biking, or swimming).
• Stress & Sleep: Get 7–9 hours of quality sleep by sticking to a schedule and minimizing blue light at night.

I’m starting these lifestyle changes now and plan to test again in one week. I’ll be documenting everything—from the changes I make to whether my inflammation improves—because I know I’m not alone on this journey.

If you’re navigating chronic inflammation or autoimmune conditions that don’t show up clearly on tests, this device might be worth exploring. It feels empowering to get real-time feedback from the comfort of home.

Stay tuned for my next update, and if you’ve tried the COR1 or are managing hidden inflammation, I’d love to hear your story.
