Upload a lab PDF and OnHealthOS organizes your results, tracks biomarkers over time, and writes a plain-English summary plus thoughtful questions for your next doctor visit.
We extract biomarkers, units, and reference ranges. Manual entry if anything is missing.
See how each biomarker moves across visits — not just one snapshot.
No scary jargon. Gentle language that respects you and your clinician.
Walk into your appointment prepared with concrete things to ask.
Stored locally in your browser. No accounts shared, no surprises.
Not a diagnosis, not advice. A calmer way to read what you already have.
OnHealthOS is educational only. It is not medical advice, not a diagnosis, and not for emergency care. Always discuss your results with a licensed clinician.
