What is a fasting blood sugar test?
South Asians are at a very high risk for diabetes. A fasting blood sugar test is done after a person fasts for 10 to 12 hours. It determines if you have diabetes or pre-diabetes. The results are measured as follows:
- Less than 100 mg/dL = Normal
- 100-125 mg/dL = Pre-diabetes
- Greater than or equal to 126 mg/dL = Diabetes
The A1C or glycohemoglobin test is another type of test that has been used to monitor individuals with established diabetes. The A1C test indicates your average blood sugar levels over the past 2-3 months. A level between 5.7-6.4 percent may indicate an increased future risk of diabetes or prediabetes. A value of 6.5% or greater would indicate diabetes. No fasting is required to have this test done.
