Specimen Requirements

Acceptable:  Green-top tube, gold-top serum gel tube, or plain, red-top tube

Specimen: 0.25 mL of lithium heparin plasma or serum

Collection Instructions: For glucose testing a fasting specimen is preferred. Tube should be kept capped as much as possible to avoid decreasing the CO2 concentration. Bilirubin is photosensitive. Specimen must be protected from light.

Note: Elevated platelets can cause a falsely elevated serum potassium level because of the release of potassium during clotting process. Specimens from patients with elevated platelet counts must be drawn in a heparinized plasma tube.
