The C-peptide test is used to determine if a patient is still producing what?

  1. Glucose

  2. Insulin

  3. Cortisol

  4. Estrogen

The correct answer is: Insulin

The C-peptide test is used to determine if a patient is still producing insulin. Insulin is a hormone produced by the pancreas to regulate blood sugar levels. Glucose is a type of sugar found in the bloodstream and is not produced by the body. Cortisol is a hormone produced by the adrenal glands and is not tested for with the C-peptide test. Estrogen is a hormone produced by the ovaries, so it would not be relevant in this test for patients of any gender.
