How many calories should be eaten before a blood test for diagnosing diabetes?
The criteria for diagnosing diabetes relies on either an oral glucose tolerance test or checking a blood sugar in the laboratory. A single abnormal check should be verified with a second determination. The blood tests are usually done fasting, but they can be done two hours after eating. The amount of carbohydrate should be reasonable but not necessarily fixed. A usual meal is all that is requested. If your doctor is going to do the two-hour post-meal sugar, you can eat your usual meal.
