About C-Peptide (1 hr post glucose)
This version of the C-Peptide test is taken one hour after a glucose load, showing how your pancreas responds to a sugar challenge rather than just your baseline. It is often used alongside the fasting version for a fuller assessment.
No fasting is required for this specific sample since it is taken after the glucose challenge. Results are available the same day.
How to Prepare
- Follow your doctor's instructions on the glucose load timing.
- This sample is drawn exactly one hour after glucose intake.
