I get lab tests on blood precribed by my regular doctor as well as a specialist urologist. My doctor sends me to the lab in the morning and my blood sugar is normal. The specialist operates in the morning so has afternoon hours for consulting. My blood tests for him come back with high sugar levels. He recommends further tests to my regular doctor. Each gets a duplicate of the results. Neither one has guessed that I have a sweet tooth and generally finish my healthy carrot+banana+whole grain bread lunch with a candy bar or equivalent. I wonder if they will ever figure it out?
