In an annual supplement to the journal Diabetes Care, published Dec. 29 by the American Diabetes Association, the A1C test is given a prominent role in the 2010 guidelines for diabetes screening, diagnosis and prevention.

At least 50 million adults and children in the U.S. may be well on their way to developing type 2 diabetes, according to John Buse, M.D., Ph.D., professor of medicine and endocrinology chief at the University of North Carolina at Chapel Hill.

In this video Doctor O’Donovan explains the C-peptide blood test including 1. What C-peptide is 2. Why the test is used 3. What the result of the test might mean.

C-peptide can be useful as a marker of insulin production.

High concentrations of C-peptide within the bloodstream generally indicate high concentrations of insulin. This may be due to excessive insulin production by the body or insulin resistance. High concentrations of C-peptide also are seen with insulinomas which is a tumour of the pancreas that causes excess insulin to be produced. It can also be seen in other disorders such as hypokalaemia, pregnancy, Cushing’s syndrome, and kidney disease.

Low concentrations of C-peptide are seen when insufficient insulin is being produced by the beta cells or when production is suppressed by injected insulin.

    From my experience after getting rid of my gonorrhoea, I have come to understand that herbal remedies are the real solution and cure for STDs/STIs because I have gone through medical treatments with no solution from them and I hope anyone with any type of sexually transmitted infection to seek for herbal treatment or reach out to doc Odion for his effective herbal treatment.
