24-Hour Urine C-Peptide Test (Labcorp)
What is C-peptide?
C-peptide is a byproduct released by the pancreas during the production of Insulin. Insulin helps transport glucose (sugar) throughout the body for energy. Measuring C-peptide levels can help determine the amount of insulin the body is producing.
How is C-peptide connected to diabetes?
In people with diabetes, the body either doesn't produce enough insulin or can't use insulin effectively. If C-peptide is low, it may indicate that a person's body isn't making enough Insulin. If C-peptide levels are normal, it may mean that the person is producing Insulin but isn't able to utilize it to control blood sugar levels. How the body produces C-peptide can help to differentiate between type 1 and type 2 diabetes.
Why should you take a C-Peptide Urine Test?
C-peptide testing is usually done if someone has unusually high or low blood sugar levels but doesn't know the cause. It is also done to monitor insulin production in people who take insulin medication for diabetes. C-peptide can be measured in urine or blood. Both are effective, but urine testing may be preferable for people who are not comfortable with frequent blood draws. Request A Test also offers a C-peptide Blood Test.
How long does a C-peptide Urine Test take?
The turnaround for this test is typically 2-5 business days.

Requirements:
24-Hour Urine Collection:
Obtain a specimen container and collection instructions from the lab after placing your order. On the day of collection, urinate at 8 AM and discard the specimen. Then collect all urine, including the final specimen voided at the end of the 24-hour collection period (ie, 8 AM the next morning). Take the specimen to the lab as soon as possible after collection is complete.
It is recommended that someone taking Biotin (also known as vitamin B7 or B8, vitamin H, or coenzyme R) stop consumption at least 72 hours prior to the collection of a sample.
