Clinical Significance
The glucagon assay is useful primarily when considering a glucagon-secreting tumor of the pancreas. Glucagonomas cause an unusual but characteristic syndrome consisting of a rash, mild diabetes, weight loss and hypoamninoacidemia. Measurement of plasma glucagon confirms the diagnosis; glucagon levels are very high in the setting of glucagonoma.
