C-peptide is used to monitor insulin production and kidney function. The test is not used to diagnose diabetes. Instead, it is used to determine how much insulin a person's pancreas is still producing.
Sometimes a C-peptide test may be used to help evaluate a person diagnosed with metabolic syndrome, a set of risk factors that includes abdominal obesity, insulin resistance, dyslipidemia, and hypertension.
High levels of C-peptide generally indicate increased production of insulin. This may be in response to high levels of blood glucose and/or insulin resistance. High levels of C-peptide are also seen with pregnancy, Cushing's syndrome, and kidney dysfunction.
Low levels are most commonly associated with insulin treatment and/or hypoglycemia.
Fasting for 14-16 hours is required. Take all medications as prescribed. Do not take your supplements the morning of the blood draw.
