A guide to discuss with your doctor, not a prescription. Do not change insulin or other medicine doses from this page. The file is read on your phone or computer and is never uploaded anywhere.

1. About you

Targets to use

Latest HbA1c optional, %

I take insulin I take gliclazide, glimepiride or another sulfonylurea

"Older or at high risk" is for people who are frail, have many other illnesses, or have had severe lows. Your doctor can tell you which fits.

2. Your data

Choose your CSV file, or drop it here.

Works with FreeStyle Libre (LibreView), Dexcom Clarity and Medtronic CareLink exports, and most other CSV files with a time and a glucose column.

How to export the file

FreeStyle Libre: sign in at libreview.com on a computer, open Glucose History, and choose Download glucose data. Your doctor's LibreView account can do the same for a Libre Pro sensor.
Dexcom: sign in to Dexcom Clarity, choose Export, pick the dates and save the CSV.
Medtronic: in CareLink Personal, open Reports, choose Data Table (CSV) and save it.
Other sensors: use the app's export or share option and choose CSV. If the file has a date and time column and a glucose column, it will usually work.

Targets used (international consensus 2019)

Group	In range	Below range	Above range
Type 1 and type 2 (and children, ISPAD 2024)	70 to 180: above 70%	below 70: under 4%; below 54: under 1%	above 180: under 25%; above 250: under 5%
Older or high risk	70 to 180: above 50%	below 70: under 1%	above 250: under 10%
Pregnancy, type 1	63 to 140: above 70%	below 63: under 4%; below 54: under 1%	above 140: under 25%
Pregnancy, type 2 or GDM	63 to 140: no set percentage	keep to a minimum	keep to a minimum

CV 36% or less for all groups. Data: 14 days with at least 70% capture (10 days with 80% or more is acceptable). Events start after 15 minutes beyond a threshold and end after 15 minutes back. GRI = 3.0 × (very low + 0.8 × low) + 1.6 × (very high + 0.5 × high), zones A to E in steps of 20. Pattern prompts (overnight fall of 50 mg/dL, meal rise of 50 mg/dL, interquartile range of 90 mg/dL) are rules of thumb, not consensus values.

Get help now if

Your glucose is below 70 mg/dL and does not rise after two rounds of fast sugar, or you are too drowsy to swallow. Someone should give sugar or glucagon and call for help.
Your glucose stays above 300 mg/dL, or you have type 1 diabetes and your blood ketones are 1.5 mmol/L or more, or you are vomiting.
The sensor reading does not match how you feel. Check with a finger-prick before acting on it.
