HiMarky74.
Tried to find reference ranges for your c-peptide results. This is what I came up with.
A standard reference range is not available for this test. Because reference values are dependent on many factors, including patient age, gender, sample population, and test method, numeric test results have different meanings in different labs. Your lab report should include the specific reference range for your test.
I strongly recommend that you discuss your test results with your doctor.
