C-peptide
This test measures the level of
C-peptide in a blood. Proinsulin is the
inactive precursor of insulin and is synthesized in the beta cells of
the pancreas. Cleavage of proinsulin produces insulin and
C-peptide,
which are stored in the beta cells. When insulin is required and
released into the bloodstream to help transport glucose into the body’s
cells (to be used in energy production), equal amounts of
C-peptide also
are released. This makes
C-peptide useful as a marker of insulin
production.
C-peptide can be used to help evaluate the production
of endogenous insulin (insulin made by the body) and to help
differentiate it from exogenous insulin (insulin that is not produced by
the body and so does not generate
C-peptide).
