Studies show a relationship between your HbA1c result and your blood glucose test results. The chart below shows the approximate relationship between the two tests.
| HbA1c % | Mean Blood Glucose (mg/dl) |
Average Plasma Glucose (mg/dl) |
Interpretation |
|---|---|---|---|
| 4 | 61 | 65 | Non-Diabetic Range |
| 5 | 92 | 100 | |
| 6 | 124 | 135 | |
| 7 | 156 | 170 | Target for Diabetes in Control |
| 8 | 188 | 205 | Action Suggested according to ADA guidelines |
| 9 | 219 | 240 | |
| 10 | 251 | 275 | |
| 11 | 283 | 310 | |
| 12 | 314 | 345 |
Test Frequency and Other Tests
You should get an HbA1c test at least two times a year if your blood sugar is
in the target range and stable. If you are taking insulin, if your treatment
changes or your blood sugar stays too high, you should get the HbA1c test at
least every 3 months until your blood sugar level improves. Since about 50%
of the HbA1c result is from the last 30 days, your physician may wish to
perform the test more frequently to check the effect of any "conntreatment"
changes.
In addition to HbA1c and daily blood glucose testing, other important tests
for diabetes care include: dilated eye exam, foot examination, blood
pressure, kidney function (Microalbumin test), and lipid profile. Be sure to
ask your physician about all of these tests.
