  • The body is effectively using insulin.
  • Low or absent insulin production by the body
  • Normal blood glucose levels
  • Efficient glucose metabolism
  The correct answer is: Low or absent insulin production by the body. Explanation: C-peptide is a byproduct of insulin production. When insulin is synthesized by the pancreas, it is initially produced as a proinsulin molecule, which is then split into two parts: insulin and C-peptide. Both are released into the bloodstream in roughly equal amounts.
  • Low or absent C-peptide levels typically indicate that the pancreas is producing little to no insulin. In type 1 diabetes, the autoimmune destruction of pancreatic beta cells leads to a significant reduction or complete cessation of insulin production, which results in low or absent C-peptide levels.
  • In contrast, in type 2 diabetes, the pancreas may still produce insulin, but the body is resistant to its effects. C-peptide levels in type 2 diabetes may be normal or even elevated due to increased insulin production as a compensatory mechanism.
Other options:
  • The body is effectively using insulin: If insulin is being used effectively, you would expect to see normal or higher C-peptide levels because insulin production would be normal or compensating for insulin resistance.
  • Normal blood glucose levels: Normal glucose levels would not directly correlate with low C-peptide levels, as low C-peptide suggests inadequate insulin production, which would typically lead to high glucose levels.
  • Efficient glucose metabolism: Efficient glucose metabolism would require adequate insulin levels, and low C-peptide would indicate the opposite (poor insulin production).
Therefore, a low level of C-peptide in the blood is a clear indicator of low or absent insulin production by the body, commonly seen in type 1 diabetes.
