Below 140: But there are a lot of variables that can affect this - how long ago someone ate, how much they ate, the mix of carbs, fat, and protein, as well as the mix of simple and complex carbs. For this reason, a fasting blood sugar is preferred for determine whether or not someone has diabetes.

Wide range: After a meal, the glu can vary a lot, depending on what you ate, when you ate, and how fast your GI tract digests the food. A random glucose of more than 200 is indicative of diabetes, but it should be verified with a fasting glucose or an a1c.
