Frequently asked questions

How do I fill in a blood sugar log?

Write the date, then each reading from your meter in its column: fasting, after breakfast, before and after lunch, before and after dinner, and bedtime. Leave a box empty if you did not test then. Use the notes for meals, activity or anything your care team asked you to record.

mg/dL or mmol/L: which should I choose?

Use the unit your meter shows. The United States mostly uses mg/dL; the UK, Canada, Australia and much of Europe use mmol/L. The unit is printed in the header so nobody reading the sheet has to guess.

When should I test my blood sugar?

Follow the testing schedule your doctor, nurse or diabetes educator gave you. The log has columns for the usual times, and you only fill in the ones you were asked to measure.

Can I record insulin doses?

Yes. The Insulin column is on by default for the dose and time; switch it off if you do not use insulin.
