I don't think you're going to have to wait that long. My doctor told me last week that the upper limit for the fasting glucose test has just been dropped by 5 points (from 105 to 100, IIRC). Those 'normal' 101's and 102's of last year aren't now considered normal.
Lord only knows what they've done with the A1C (long-term) glucose test. A few years ago, I dropped 50 pounds with a corresponding drop in my A1C results. Unfortunately, they were dropping the limit faster than I was dropping my level. As soon as I'd get below the old limit, they'd drop the limit again.
My doctor told me last week that the upper limit for the fasting glucose test has just been dropped by 5 points... So the Dr.'s can ensure a steady stream of scared patients and keep ripping off the insurance companies. A couple of years ago I got a non-fasting test and was told I was OK. That was December. In January I returned to get the stitches out of my original wound and was told I had diabetes. As of JAN 1 the limit had dropped and I was told about all the money I could spend with the Dr. treating this horrible disease. I told him to kiss my diabetic @ss, I'll treat it when he takes my toes off.
