What an AGP shows

An ambulatory glucose profile stacks days or weeks of readings onto a single 24-hour view. The line through the middle is your median; the darker band around it holds the middle half of your readings; the lighter band reaches from the 5th to the 95th percentile. A narrow band means your days repeat themselves; a wide one means the same clock time can go very different ways.

The tinted stripe is the 70 to 180 mg/dL band most adult targets are built around. Where your median rides above it, or the band dips below it, you have found the hours worth paying attention to, which is far more useful than judging any single reading.

Every formula behind this report, from GMI to the percentile profile, is published in the open on the methodology page.

Common questions

Is my glucose data uploaded anywhere?

No. Your browser opens the file on your device, the way a spreadsheet app opens a file locally. There is no upload endpoint behind this page, nothing is stored, and the report disappears when you close the tab. If you want reports that persist, a free SteadyRange log keeps readings in a private database you control.

Which files work?

Dexcom Clarity, LibreView, and Tidepool CSV exports are recognized automatically, in both mg/dL and mmol/L. Beyond those, any CSV with a date column and a glucose column works: the unit is detected from the numbers themselves, and you can switch it if the guess is wrong.

How many days of data do I need?

The standard AGP window is 14 days, which is usually enough for the daily pattern to settle. The tool will draw a report from less, with a note to hold short-window patterns lightly, and can widen to 30 or 90 days when your file covers them.

What is a good time in range?

The widely cited consensus goal for most adults is above 70% of readings between 70 and 180 mg/dL. Targets are individual, though: the right band and the right percentage are a conversation with your care team, so treat the goal line as a reference point rather than a grade.

How is GMI different from a lab A1C?

GMI runs your average glucose through the published Bergenstal formula printed on standard AGP reports, while a lab A1C measures glycated hemoglobin in your blood. They usually land close together and often differ by a few tenths of a percent, which is normal and can itself be useful to know.

Can I save or share the report?

Use Print or save as PDF. The page prints just the report card, so your browser's print dialog can produce a clean PDF to keep or hand to your clinician. Nothing is saved on our side.

Want this without the export step?

SteadyRange builds time in range, GMI, and this daily profile from your ongoing readings, keeps them current as you log, and turns them into a clinician-ready report when you need one. Free to start, on a private log you control.

General information, not medical advice. An AGP built from an export helps you see patterns; it is not a diagnosis, and treatment changes belong in a conversation with your care team. For plain-language definitions, see the glossary.
