Fasting blood sugar test. A fasting blood sugar level less than 100 mg/dL (5.6 mmol/L) is normal. A fasting blood sugar level from 100 to 125 mg/dL (5.6 to 6.9 mmol/L) is considered prediabetes. If it's 126 mg/dL (7 mmol/L) or higher on two separate tests, you have diabetes.

A blood sugar level of between 3.3 or 3.9 mmol/L (60 to 70 mg/dL) is generally considered the lower limit for blood glucose. However, symptoms of hypoglycemia do not usually manifest until levels have reached a low of between 2.8 to 3.0 mmol/L (50 to 54 mg/dL).

Doctors may say you have hyperglycemia if your blood sugar is higher than 130 mg/dL after not eating or drinking for at least 8 hours (called fasting hyperglycemia) or if your blood sugar is higher than 180 mg/dL 2 hours after a meal (called postprandial or after-meal hyperglycemia).

For most people without diabetes, blood sugar levels before meals hover around 70 to 80 mg/dL. For some people, 60 is normal; for others, 90.

A simple blood test can tell you what your blood sugar level is. This is usually measured after fasting for 8 hours (no food, and only water to drink). is 70 to 89 mg/dl, according to the American Diabetes Association. If your blood sugar level is in the “high normal” range, you are still at risk for type 2 diabetes.

A fasting blood sugar level from 100 to 125 mg/dL (5.6 to 7.0 mmol/L) is considered prediabetes. This result is sometimes called impaired fasting glucose. A fasting blood sugar level of 126 mg/dL (7.0 mmol/L) or higher indicates type 2 diabetes.

Below 7.8 mmol/L, the test is normal. Above 11.0 mmol/L, it is gestational diabetes. If it is between 7.8 and 11.0 mmol/L, the attending physician will ask for a second blood test measuring fasting blood glucose (sugar) levels, then for blood tests taken 1 hour and 2 hours after drinking 75 g of glucose.

Hyperglycemia, the term for expressing high blood sugar, has been defined by the World Health Organisation as: Blood glucose levels greater than 7.0 mmol/L (126 mg/dl) when fasting. Blood glucose levels greater than 11.0 mmol/L (200 mg/dl) 2 hours after meals.

The normal fasting blood glucose level is below 100 mg/dl. A person with prediabetes has a fasting blood glucose level between 100 and 125 mg/dl. If the fasting blood glucose level is to 126 mg/dl or above, a person is considered to have diabetes.

Fasting blood glucose level -- Diabetes is diagnosed if it is 126 mg/dL (7 mmol/L) or higher two different times. Random (non-fasting) blood glucose level -- You may have diabetes if it is 200 mg/dL (11.1 mmol/L) or higher, and you have symptoms such as increased thirst, urination, and fatigue.

According to the American Diabetes Association, normal blood sugar levels for a person of any age include: Fasting blood sugar (in the morning, before eating): under 100 mg/dL. 1 hour after a meal: 90 to 130 mg/dL. 2 hours after a meal: 90 to 110 mg/dL.

The results of a fasting test with respect to glucose levels in the body are as follows: Normal: 3.9 to 5.4 mmols/l (70 to 99 mg/dl) Prediabetes or Impaired Glucose Tolerance: 5.5 to 6.9 mmol/l (100 to 125 mg/dl)

Gestational diabetes For the three-hour test: A normal fasting blood glucose level is lower than 95 mg/dL (5.3 mmol/L). One hour after drinking the glucose solution, a normal blood glucose level is lower than 180 mg/dL (10 mmol/L).

A blood sugar level less than 140 mg/dL (7.8 mmol/L) is normal. A reading between 140 and 199 mg/dL (7.8 mmol/L and 11.0 mmol/L) indicates prediabetes. A reading of 200 mg/dL (11.1 mmol/L) or higher after two hours suggests diabetes.

Hypoglycemia needs immediate treatment when blood sugar levels are low. For many people, a fasting blood sugar of 70 milligrams per deciliter (mg/dL), or 3.9 millimoles per liter (mmol/L), or below should serve as an alert for hypoglycemia.
