Just got back my yearly lab work results from a routine physical, and it shows a slightly elevated GGT value of 95 (actually, when I look back at last year s results, GGT was 100, so it s not changed much). I m 62 years old, 6 tall, 168 pounds, in relatively good health. Other lab tests such as ALT (37), AST (36), Alkaline Phos (68), Bilirubin (1.1), and Amylase (23) are all in normal range, as are cholesterol, triglycerides, glucose, and A1c. I m not experiencing any sort of digestive symptoms (no heartburn, indigestion, stomach pains, etc).
