How to Estimate A1c Levels

Most diabetic patients check their blood sugar several times a day, based on what their doctors recommend. Every three months or so, doctors check the A1c (glycosylated hemoglobin level) of diabetic patients to monitor their progress. The A1c reflects an average of blood sugar levels in the blood over the previous three months. However, the numbers used to reflect the A1c level do not match up with typical blood sugar readings. Therefore, it is often difficult for patients to estimate A1c for themselves.

Instructions

• 1

  Keep a record of all of your blood sugar readings over the course of 120 days. Most doctors recommend keeping a record at all times so they can see what your daily readings look like, as well as consider the A1c.

• 2

  Add up all the readings you have taken over the past 120 days.

• 3

  Divide the answer by the total number of readings you took. This results in your estimated average glucose (eAG).

• 4

  Visit the American Diabetes Association website to translate your eAG into your estimated A1c number. To locate the calculation, click on "Living with Diabetes" and then the "Estimated Average Glucose (eAG)" link.

• 5

  Click on the "eAG --> A1c" option for the calculator near the bottom of the page. Enter your eAG from Step 3 and click "Calculate." This gives you your estimated A1c.
