Glucose homeostasis, when operating normally, restores the blood sugar level to a narrow range of about 4.4 to 6.1 mmol/L (79 to 110 mg/dL) (as measured by a fasting blood glucose test). [10] The global mean fasting plasma blood glucose level in humans is about 5.5 mmol/L (100 mg/dL); [11] [12] however, this level fluctuates throughout the day ...
A level below 5.6 mmol/L (100 mg/dL) 10–16 hours without eating is normal. 5.6–6 mmol/L (100–109 mg/dL) may indicate prediabetes and oral glucose tolerance test (OGTT) should be offered to high-risk individuals (old people, those with high blood pressure etc.). 6.1–6.9 mmol/L (110–125 mg/dL) means OGTT should be offered even if other ...
Glucose levels vary before and after meals, and at various times of day; the definition of "normal" varies among medical professionals. In general, the normal range for most people (fasting adults) is about 4 to 6 mmol/L or 80 to 110 mg/dL. (where 4 mmol/L or 80 mg/dL is "optimal".)

The normal level for fasting blood sugar in non-diabetic patients is 70 to 99 mg/dL (3.9 and 5.5 mmol/L). Another useful test that has usually done in a laboratory is the measurement of blood HbA1c (hemoglobin A1c) levels. In the blood, there is a molecule called hemoglobin which carries oxygen to the cells. Glucose can attach itself to this ...
A postprandial glucose (PPG) test is a blood glucose test that determines the amount of glucose in the plasma after a meal. [1] The diagnosis is typically restricted to postprandial hyperglycemia due to lack of strong evidence of co-relation with a diagnosis of diabetes .
The glycemic response (or glycaemic response) to a food or meal is the effect that food or meal has on blood sugar (glucose) levels after consumption. [1] It is normal for blood glucose and insulin levels to rise after eating and then return again to fasting levels over a short period of time. This is particularly so after consumption of meals ...
As long as the pancreatic beta cells are able to sense the glucose level and produce insulin, the amount of insulin secreted is usually the amount required to maintain a fasting blood glucose between 70 and 100 mg/dL (3.9–5.6 mmol/L) and a non-fasting glucose level below 140 mg/dL (<7.8 mmol/L).
