Hypoglycemia Panel (Sulfonylureas), Serum or Plasma
Use
This test is used as a preferred method to evaluate if the etiology of hypoglycemia is due to sulfonylurea ingestion. Sulfonylureas are a class of medications often used to manage blood sugar levels in type 2 diabetes, and their presence in blood can indicate accidental or intentional ingestion.
Special Instructions
This test is not performed at ARUP. Separate specimens must be submitted if multiple tests are ordered. The test requires either serum or plasma specimens obtained from plain red or gray (sodium fluoride/potassium oxalate) tubes. Immediate separation of cells from plasma or serum is necessary.
Limitations
The test is performed through a non-ARUP laboratory using High Performance Liquid Chromatography-Tandem Mass Spectrometry. Limitations may include interferences from substances or metabolites not targeted by the assay. Additionally, the transport and storage conditions must be followed strictly to maintain sample integrity.
