Insulin

Insulin. Insulin levels can be also useful in predicting susceptibility to the development of type II diabetes. It can also be measured to estimate a patient's capacity for insulin secretion or in the evaluation of insulin sensitivity (eg, oral glucose tolerance test). Although the adequacy of pancreatic insulin synthesis is frequently assessed via the determination of C-Peptide, fasting insulin is also measured to assess insulin resistance.

TEST PREPARATION:
