Clinical Info

The determination of insulin in serum is primarily used for the diagnosis of glycemic disorders in diabetic and pre-diabetic
patients in the assessment of insulin resistant syndromes. Insulin is synthesized by the pancreatic beta cell as a precursor,
 proinsulin. Proinsulin is processed to insulin and C-peptide, a contiguous peptide between the insulin A and B chains, as
 it passes through the cell. The C-peptide in the proinsulin ensures correct folding and processing of proinsulin as it passes 
through the cell. Both insulin and C-peptide are released together from the beta cells in response to increased glucose levels. 
Because of differences in half-life and hepatic clearance, peripheral blood levels of C-peptide and insulin are no longer
equimolar but remain highly correlated. A steady-state plasma glucose test in individuals undergoing an insulin suppression 
test to assess insulin resistance found that the combination of insulin and C-peptide was a better indicator of insulin resistance 
than either one individually.
