Clariti is a free tool that turns any standard blood test PDF into a clear A–F health score across six domains — benchmarked against optimal ranges for your age and sex. No account. No subscription. No blood draw. Just upload and understand.
The report looks like a wall of numbers
You get your results back. There are dozens of values, reference ranges, flags — and almost no explanation of what any of it actually means for your health. Most people either ignore it entirely or spend an hour Googling each line.
The doctor's explanation doesn't stick
The consultation makes sense in the room — your doctor walks you through it, it all clicks. But a week later, it's gone. You can't remember what they said about your TSH, or which number was the one to watch, or why your vitamin D mattered. There's no record of the explanation, only the numbers.
No plain-English explanation per biomarker
What does LDL actually do? Why does ferritin matter? What's the difference between TSH and T4, and why should you care which one is low? Standard lab reports give you the value and a reference range — nothing more. Understanding the biology behind each marker requires either expensive specialist time or a lot of research you shouldn't have to do yourself.
No guidance on what to do next
Even if you understand your numbers, knowing what to do about them is another gap entirely. How do you improve a low HDL? What lifestyle changes move ferritin? Which values respond to diet, which to exercise, which to sleep? Most people are left without any actionable next step beyond "follow up in six months."
Clariti was built to fix all four of these. Upload your PDF, get a clear score across six health domains, read a plain-English breakdown of every biomarker that matters, and leave with concrete steps to improve or maintain each one. No consultation required. No forgetting. Always there when you need it.
One upload. One score. Six domains. A complete picture of your bloodwork in under 60 seconds.
Any standard blood test from any lab — Quest, LabCorp, NHS, or your local clinic in 131 countries. Your file never leaves your browser.
Every value is scored against optimal ranges — not just whether it's flagged abnormal — and adjusted for your age and biological sex.
An overall health score plus individual grades for cardiovascular, metabolic, kidney, liver, blood, and inflammatory health.
Optimal · 90–100
Ideal range. Lowest disease risk.
Good · 75–89
Good with minor room to improve.
Fair · 55–74
Suboptimal but not flagged.
Below Optimal · 35–54
Worth discussing with your doctor.
Poor · 20–34
Follow up with your doctor soon.
Critical · 0–19
Seek medical attention.
Standard lab reports flag values as normal or abnormal using reference ranges set to capture the middle 95% of the population. These ranges are designed to avoid false positives — not to identify optimal health.
You can have a fasting glucose of 99 mg/dL, a TSH of 4.0, and a vitamin D of 22 ng/mL — all technically "normal" — and still feel fatigued, foggy, and suboptimal. Your lab report says you're fine. But you're not at your best.
Clariti scores against optimal ranges drawn from functional medicine research, giving you a grade that actually reflects where your health stands — not just whether you cleared a minimum threshold.
Clariti scores every biomarker across six distinct systems so you know exactly where your strengths and gaps are.
Cardiovascular
LDL, HDL, triglycerides, total cholesterol, hs-CRP
Metabolic
Fasting glucose, HbA1c, insulin resistance markers
Kidney
Creatinine, eGFR, BUN, uric acid
Liver
ALT, AST, GGT, albumin, bilirubin
Blood
CBC: hemoglobin, RBC, WBC, platelets, ferritin
Inflammatory
hs-CRP, ESR, white blood cell count
Clariti uses PDF.js to read your file entirely inside your browser. Your blood test data is never transmitted to any server, never stored, and never shared. The moment you close the tab, it's gone.
The only data we store is anonymous and aggregated — age band, sex, country, and domain scores — used solely to improve population benchmarks. No names. No raw values. No personal identifiers.
Anyone who has received a blood test and wants to understand it — not just whether it's "normal."
🧑⚕️
Your lab says everything is normal but you're still fatigued, foggy, or not at your best. Clariti shows where your results are suboptimal even within the "normal" range.
