Q:

What should a random blood glucose level be for a diabetic and a non-diabetic?

A:

A diagnosis of diabetes is two fasting blood glucoses at 126 or above. Random testings at 200 and above are also generally accepted as a diagnosis. It is customary to follow with an oral glucose tolerance test where glucose is measured four times over a two hour period after drinking a 75 gram cola drink. This is a test routinely administered to pregnant women at 28 weeks. There are specific number ranges for each time period.
