what is normal insulin level in body
Insulin is a hormone that is produced and stored in the beta cells of the pancreas. Insulin helps transport glucose, the body's main source of energy, from the blood to within cells. If a person makes too little insulin or is resistant to its effects, cells starve. Monitor the amount of insulin produced by the beta cells in the pancreas (endogenous); in this case, a C-peptide test may also be done.
