I’m a LADA type 1 diagnosed May of 2018. At diagnoses I had a C-Peptide of 0.92
Last month (15 months later) I had a fasting C-Peptide of 0.35.
I’m planning to pay for another C-Peptide on my own but this time not fast.
My thoughts are because I was fasting and I also take basal/bolus insulin there was little need for my body to make much insulin at the time leading to the 0.35 rest result. At test time my fasting glucose was 80.
My theory is if I eat something prior to the blood draw causing my sugar to rise my body will respond making what insulin it can and leading to a higher C-Peptide result.
How long before the blood draw do I need to eat for it to make a detechable change in C-Peptide? (I’m guessing an hour should be enough).
Thank you for your help.
