How to do Glucose test

A glucose test is a type of blood test used to determine the amount of glucose in the blood.

There are several different kinds of glucose tests:

 "Fasting blood sugar" (FBS) -- 12 hours after eating

 Postprandial -- 2 hours after eating

 Glucose tolerance test -- continuous testing

A range of 4 to 7 mmol/l (72 to 126 mg/dl) before a meal is normal.

A level of < 10 mmol/l (180 mg/dl) 90 minutes after a meal is normal.

A range of 7 to 8 mmol/l (126 to 144 mg/dl) at bedtime is normal.

After a 12 hour fast, a range of 3.9 to 6.5 mmol/l (70.2 to 117 mg/dl) is normal. (a level of 6.7 to 7 mmol/l (120.6 to 126 mg/dl) is considered a sign of prediabetes)
