Test ID: GLP
Glucagon, Plasma
Specimen Type
Describes the specimen type needed for testing
Plasma EDTA
Specimen Required
Defines the optimal specimen. This field describes the type of specimen required to perform the test and the preferred volume to complete testing. The volume allows automated processing, fastest throughput and, when indicated, repeat or reflex testing.
Collection Container/Tube: Lavender top (EDTA)
Submission Container/Tube: Plastic vial
Specimen Volume: 2 mL
Collection Instructions:
1. Fasting.
2. Prechill tube at 4 degrees C before drawing the specimen.
3. Draw the prechilled tube, and process as follows:
a. After drawing specimen, chill tube in wet ice for 10 minutes.
b. Centrifuge in a refrigerated centrifuge or in chilled centrifuge cup.
c. Immediately after centrifugation, remove plasma, place in a plastic transport vial (Supply T465), and freeze.
Forms: If not ordering electronically, submit a General Request Form (Supply T239) with the specimen.
Specimen Minimum Volume
Defines the amount of specimen required to perform an assay once, including instrument and container dead space. Submitting the minimum specimen volume makes it impossible to repeat the test or perform confirmatory or perform reflex testing. In some situations, a minimum specimen volume may result in a QNS (quantity not sufficient) result, requiring a second specimen to be collected.
0.45 mL
