I'm on Medicare and I have a supplement from Anthem . They are requiring me to have a c peptide test before they will cover my pump supplies. The last time I had a c peptide test was about 5 years ago and I was told to hold my insulin injections before the test so at that time my BG was sky high and and my c peptide was less than 1. This time I'm told to continue wearing my Insulin pump and that there is no need to fast. I'm afraid that if I'm just less than one like .7-.9 that my insurance won't cover me for the supplies.
I've been a diabetic for 12 years and I've had the pump for 3 years, and it has saved my life. What is the best way to insure a low reading below .6? Should I go ahead and fast the night before the test or should I eat? I'm just really scared that it won't be low enough for me to be covered.
Thank you in advance for any suggestions
