Clinical Utilities
Evaluation of suspected insulinoma characterized by hypoglycemia and increased serum insulin concentration
Detecting drugs that stimulate insulin secretion
Drugs detected by this procedure are:
-The first-generation sulfonylureas: chlorpropamide (Diabinese), tolazamide, and tolbutamide (Orinase)
-The second-generation sulfonylureas: glimepiride (Amaryl), glipizide (Glucotrol), and glyburide (Glibenclamide)
-The meglitinides: repaglinide (Prandin) and nateglinide (Starlix)
-The thiazolidinediones: pioglitazone (Actos) and rosiglitazone (Avandia)
This test is not intended for therapeutic drug monitoring but could be used to monitor compliance.

Screening cutoff concentrations
Chlorpropamide: 100 ng/mL
Glimepiride: 20 ng/mL
Glipizide: 5 ng/mL
Glyburide: 5 ng/mL
Nateglinide: 5 ng/mL
Pioglitazone: 20 ng/mL
Repaglinide: 5 ng/mL
Rosiglitazone: 20 ng/mL
Tolazamide: 50 ng/mL
Tolbutamide: 20 ng/mL
Note: The report indicates a specific drug is positive if that drug is detected at a concentration greater than the cutoff. The test cutoff listed for each drug is lower than the concentration that will cause increased insulin and decreased glucose.
