What are normal blood sugar levels for men?

Blood sugar, or blood glucose, is measured with a fasting blood glucose test or a random blood glucose test. Usually between 70 and 100 milligrams per deciliter is considered a normal result in the former, while below 125 milligrams per deciliter is a normal result in the latter, explains MedlinePlus.

In a random blood glucose test, the result depends on when the person last ate. Furthermore, normal value ranges can vary from one laboratory to another, and some laboratories use different measurements or may test different specimens, advises MedlinePlus. A patient should discuss his particular results with his doctor to determine their meaning.
