I have had 2 elevated Alkaline Phosphatase readings....both done after a 14 hour fast. 1st was 144, two months later it was 167. Intestinal Isoenzymes was 0, placental isoenzymes was undetectable, Bone isoenzymes was 38 and liver isoenzymes was 62. I am 47, female, type O positive blood, hemoglobin A1c is 5.8% and estimated blood glucose is 114mg/dl. I do not drink, I am about 15 lbs overweight, I watch my carb and sugar intake. I do have mild discomfort in the stomach area (mainly on the sides), nothing major, my bowels are never on a schedule and tend to mostly be loose. I am going for an abdominal sonogram in a few days but seeking a bit more information and possible culprits.
