Like "Hmmm, like James, I'm stumped too. Unless you were under some stress or just coming from some physical activity the numbers just don't add up. A 5.8 A1c is really good for anyone. Certainly not high enough to make one think diabetes. Again, as James said, allergies or possible sensitivities to preservatives. Some restaurants use a preservative for whole hard boiled eggs they keep in a liquid until needed. Only other thought (and i don't know if this applies) is "women's issues"."
