Measure Definition:

Fasting levels of insulin, glucagon, and glycosylated hemoglobin (HbA1C) can be measured before, during, and after weight loss. Along with the metabolite data, these measures can be utilized to calculate indices of insulin sensitivity and secretion (homeostatic model assessment of insulin resistance and homeostatic model assessment for b-cell function (88). 

Construct:

Laboratory Procedure

Construct Definition (and Source):

Any procedure that involves testing or manipulating a sample of blood, urine, or other body substance in a laboratory setting. (NCI)
