# C-Peptide, Ultrasensitive (Endocrine Sciences)

> This test measures the level of C-peptide, a substance released by your pancreas whenever it makes insulin. Because C-peptide and insulin are produced in equal amounts, this test helps show exactly how much insulin your body is creating on its own. It is often used to investigate the cause of low blood sugar or to help distinguish between Type 1 and Type 2 diabetes. While it tracks insulin production, this test does not measure blood sugar levels directly or diagnose specific diseases without other clinical information.
