Insulin, Intact, LC/MS/MS - 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. C-peptide is a peptide that connects insulin's 2 peptide chains and is released from proinsulin during processing and subsequently co-secreted from the pancreatic beta cell. 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. Measurement of endogenous insulin and C-peptide is useful for distinguishing (1) insulin-secreting tumors from exogenous insulin...

Measurement of endogenous insulin and C-peptide is useful for distinguishing (1) insulin-secreting tumors from exogenous insulin administration as a cause for hypoglycemia and (2) type 1 from type 2 diabetes.
Please do not exercise prior to testing. It is best that your blood is taken in a rested state.
Note: Turn around times on results are an estimate and are not guaranteed. The lab may need additional time due to holidays, confirmation/repeat testing, etc. You can contact us to discuss when your results should be ready and we will contact the lab on your behalf immediately.
