Test Code

C-Peptide PP (Post-Prandial) measures the level of C-peptide in blood after food intake (usually 2 hours post-meal). Since C-peptide is released in equimolar amounts with insulin, this test reflects natural insulin production in response to glucose stimulation.
It is particularly useful for evaluating beta-cell reserve, differentiating Type 1 vs Type 2 diabetes, assessing insulin resistance, investigating post-prandial hypoglycemia, and monitoring residual insulin secretion in patients on insulin therapy. Compared to fasting C-peptide, the PP test provides insight into dynamic pancreatic response.

Frequently Asked Questions

To measure endogenous insulin response after food intake.

PP C-peptide assesses stimulated insulin secretion, while fasting measures baseline levels.

Poor beta-cell function, commonly seen in Type 1 diabetes or advanced Type 2 diabetes.

Insulin resistance, early Type 2 diabetes, or insulinoma (with clinical correlation).

No; the test is done after a meal as instructed.

Yes, it helps distinguish endogenous insulin excess from exogenous insulin use.
