The presence of sulphonylurea drugs should be excluded in the patient who presents with a suspected insulinoma. Hypoglycaemia may occur in both diabetic and non-diabetic patients and may be caused by the surreptitious use of sulphonylurea drugs or insulin.
The clearance of the Sulphonylurea drugs is fast. They will only be detectable for 1-2 days after dosage. The composition of the metabolites is not known.
This test is not to be used for Therapeutic drug monitoring and guidance of doses
