Description
The COR One™ brings professional inflammation testing into your home. Using one drop of blood from a quick finger prick, it measures the Erythrocyte Sedimentation Rate (ESR). This tells you how quickly your red blood cells sink in the sample - a standard medical test for inflammation. You'll see your results in 30 minutes, with faster settling indicating higher inflammation levels.
Regular testing shows you exactly how your diet, sleep, and lifestyle choices affect your body's inflammation levels. Managing a health condition? Exploring food sensitivities? Or do you simply want clear data about your body's responses? The COR One™ shows you what's working so you can make better, more informed choices.

Your inflammation dashboard
The COR dashboard turns your test results into clear, actionable insights. Track your inflammation levels over days, weeks, or months to understand your body's patterns. Add quick notes about meals, workouts, sleep quality, or stress levels to reveal what affects you most.
Want to know how you compare? The dashboard shows where your inflammation levels sit relative to others in your age group.
This is a fantastic tool for tracking your inflammation. You can measure it at home instead of going to a clinic and waiting a week for the results. You can measure it weekly, and for that week you do one experiment, such as adding an anti-inflammatory supplement to your daily routine. After a week you can see a result. Did it improve your inflammation or not?
Real people, real results
Five different health goals, measured and improved with personal inflammation data. Here's what our customers discovered:
GOAL: DISEASE MANAGEMENT
Rachel's joint pain affected her art career. Using COR One™, she tracked her inflammation between doctor visits and spotted patterns her medical tests missed.
Working with her physician, she used this daily data to refine her treatment plan. Now she spends more time painting and less time worrying about flare-ups.
GOAL: INCREASED ENERGY
Michael blamed his afternoon slumps on aging. But COR One™ tests revealed specific triggers - his desk lunch habits and coffee timing were raising his inflammation.
Small schedule changes based on his personal data made a surprising difference. He stopped accepting tiredness as inevitable and started making evidence-based changes that worked.
GOAL: INCREASED LIFESPAN
At 52, James noticed his friends starting various anti-aging treatments. Instead of following trends, he chose to track what was happening inside his body with COR One™. His inflammation numbers showed clear patterns - walking in nature lowered his levels while late-night meals raised them.
Simple changes based on his personal data helped him take practical steps toward a longer, healthier life.
GOAL: HOLISTIC WELLNESS
Sofia ran a successful business but felt constantly drained. Testing with COR One™ revealed surprising inflammation triggers: her intense morning workouts and "healthy" smoothies.
By adjusting her exercise timing and switching to warm breakfasts, her inflammation dropped. Now she has hard data showing which wellness habits actually work for her body.
GOAL: PERSONALIZED NUTRITION & FOOD SENSITIVITY TRACKING
Thomas tried every diet blog's advice but still felt off. His COR One™ readings finally showed the truth - his "healthy" salad dressings and protein bars were causing inflammation spikes.
Through regular testing, he built a diet that genuinely suited his body. No more guessing games, just clear evidence of what foods work for him.

Excellent followup when I needed an update on my order and when I had questions.Thank you Bob!
I've had my COR One for about 6 months and it's been such a useful health tool! The fact that I can measure a clinically validated inflammation marker at home is great, but the best part is being able to tag readings with what I ate or did on that particular day and seeing what impact that has - so much better than blindly guessing what works for me and what doesn't.
Received the COR health device in January of this year. If you care or are concerned about your health, knowing whether you have any inflammation is a great place to start. The device is easy to set up and use with detailed written instructions and helpful videos.The lancets, included are great. The test tubes work perfectly as well.Just remember to prep your finger to get the best blood flow into the tube.But what has impressed me the most has been the customer support. Any issues I encountered or any questions I had were answered very quickly. And at times, with more detail than expected which was extremely helpful.Kudos to the entire COR Health team.
The COR ONE completely changed the way I think about inflammation. But MUCH more importantly, it has changed the way I respond to it by providing reliable, near-real-time feedback to dietary and lifestyle choices. This is literally a 'game changer'. My deepest gratitude to Bob and everyone at COR Health, Inc.
Very easy to use. App is straight forward and connection is also easy.
ESR is the dipstick of health
I believe you're in a very unique focus. The public health cost of undetected inflammation is enormous.

Frequently
asked questions
Need more info? Find it here.
How does the COR One™ measure inflammation?
The device measures your Erythrocyte Sedimentation Rate (ESR) - a key marker doctors have trusted for decades. It tracks how quickly red blood cells settle in your blood sample, which changes when inflammation is present. Our FDA-registered device brings this lab-standard test into your home.
What makes COR One™ different from typical lab tests?
Traditional inflammation testing means scheduling appointments, traveling to labs, and waiting days for results. COR One™ lets you test anytime at home and see your results in 30 minutes. This frequent testing helps you spot patterns and see how your daily choices affect your body.
How accurate are the results?
The COR One™ provides medical-grade ESR measurements - the same test labs use. We've matched our results against standard lab tests to ensure accuracy. That's why we're FDA-registered and trusted by healthcare providers.
Can I share my data with my healthcare team?
Absolutely. The COR dashboard creates clear reports of your ESR results that any doctor will understand. Many users bring their tracking data to appointments, showing how their inflammation levels change between visits. This helps inform treatment decisions and lifestyle recommendations.
How often should I measure my inflammation?
When you start, we recommend testing 2-3 times weekly for a month. This creates your baseline and helps you spot patterns. After that:
- For general health tracking: 1-2 times per week
- For food sensitivity testing: After trying new foods or during elimination diets
- For managing health conditions: As often as needed to track your progress
- For fitness optimization: Before and after changing routines
