calculated blood glucose level calculated serum insulin level calculated plasma insulin level quantitative insulin sensitivity check index 2014-02-04T18:13:36Z A calculated measurement to estimate the effect of insulin on net glucose disposal (insulin sensitivity) in an organism, calculated as 1/(log[fasting plasma insulin in uU/mL] + log[fasting blood glucose in mg/dL]), i.e., the inverse of the logarithm of the product of fasting plasma insulin level and fasting blood glucose level. The insulin and glucose levels may also be measured in any combination of blood, plasma, and serum. CMO:0002171 JSmith QUICKI clinical_measurement_ontology
