Adults. A normal blood sugar level is between 72 mg/dL and 108 mg/dL (4 to 6 mmol/L) for a healthy person. The concentration of glucose in the blood of a healthy person in the morning on an empty stomach is between 68 mg/dL and 108 mg/dL (3.8 and 6.0 mmol/L).lood sugar level (or blood sugar concentration) is the amount of glucose (a source of energy) present in your blood at any given time. A normal blood glucose level for a healthy person is somewhere between 72 mg/dL (3.8 to 4 mmol/L) and 108 mg/dL (5.8 to 6 mmol/L).
Normal blood glucose range for adults without diabetes is 70 - 100 mg/dl. Actually, the sugar levels keep on changing. They are not constant throughout the day. In the morning, low levels are noticed while after lunch, the levels rise, and then they again come down to the normal value.enerally, the levels are first measured after fasting for at least 8 hours (usually overnight fasting). This is known as fasting blood glucose. In adults, the readings that lie between 70 to 99 mg/dl (3.9 to 5.5 mmol/l) are considered as normal.
