The First At-Home Device That Tracks Your Inflammation in 30 Minutes. No Labs, No Shipping.
Most "at-home inflammation tests" aren't really at home — they're mail-in kits. You prick your finger, ship your blood, and wait days or weeks for results. By then, the number is outdated.
Fantastic for tracking inflammation at home. Measure weekly, try one change, and see if it moves your inflammation.

The system works well. I do wish I had more reference material to help me lower the number. I do exercise, never eat before noon, and never eat ultra processed foods.

Frequently
asked questions
Have any questions? We have the answers.
Sed Rate—short for Erythrocyte Sedimentation Rate (ESR)—is a composite signal of systemic inflammation. It reflects how quickly red blood cells (RBCs) settle to the bottom of a test tube, a process that accelerates in the presence of inflammatory proteins.
CRP is one inflammatory marker. Sed Rate reflects many inflammatory proteins including CRP—making it better at capturing ongoing inflammation that CRP alone might miss.
ESR is the best marker for tracking because it captures the full picture — it responds to dozens of different acute-phase proteins, stays stable enough to show real trends, and reflects both acute and low-grade inflammation. CRP can spike and fall in a matter of hours, which makes it easy to miss changes unless you test constantly. That's why COR One uses ESR — it's the gold standard for seeing whether your inflammation is truly moving in the right direction.
The COR One™ is medically accurate and FDA registered.
COR is currently available in the US and Canada. As with all products the COR One™ is subject to local regulation and requirements.
Yes. Your physician will understand your Erythrocyte Sedimentation Rate (ESR) results. Additionally, the COR dashboard allows you to print your results. You can then share them with medical professionals.
