Normal Range of Blood Sugar Level
The normal range of blood sugar levels can vary depending on the time of day, the type of test used, and the age of the individual being tested. However, in general, a normal range for blood sugar level is considered to be:

2. After eating (postprandial), blood sugar level: less than 140 mg/dL
3. Hemoglobin A1C (HbA1C) level: less than 5.7%
It is important to note that these are general guidelines and may vary depending on an individual’s specific health circumstances. It is always best to consult a healthcare provider to determine the appropriate blood sugar level range for each individual.
