519: Glucagon Print View
Glucagon ELISA    pg/mL 

PRIMARY
1 Plasma EDTA 2 (0.5) mL   Frozen - 28 Day(s)/Refrigerated - 2 Hour(s)  
ALTERNATE

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 a glucagonoma.

Collect EDTA plasma, invert several times to mix, centrifuge, and
immediately transfer the plasma into a clean, plastic screw-cap vial
and freeze at -60 to -90 degrees C. There should be no delay in
freezing as the analyte is very unstable and samples must be kept
frozen until testing.

Patient Preparation: Overnight fasting is required
Setup Schedule
Monday

Reported (Analytical Time)
