Can I eat before taking an HbA1c test if I’m on insulin?

Yes, you can eat before taking an HbA1c test, even if you’re on insulin. Unlike fasting glucose tests, the HbA1c test measures your average blood sugar levels over the last 2-3 months, so eating before the test doesn’t affect the result. You should continue taking your insulin as prescribed by your doctor. However, if you are undergoing additional tests, such as a fasting glucose test, you should follow the specific fasting instructions for those tests. Always consult your healthcare provider if you’re unsure about your testing preparations.
