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.
Overnight Fasting required

Collect EDTA plasma, gently invert several times to mix, Centrifuge and separate from cells immediately, transfer the plasma into a clean, plastic screw-cap vial and freeze.
There should be no delay in freezing as the analyte is very unstable and samples must be kept frozen until testing.y
