Specimen Collection Manual and Test Catalog
WHOLE BLOOD PROFILE, VENOUS
Geisinger Epic Procedure Code: LAB3461 Geisinger Epic ID: 45110Whole Blood
1 mL whole blood; minimum 0.4 mL.
Due to sample instability, this test may only be collected and analyzed at a performing laboratory site (see below). Expel excess air from syringe. Mix well immediately after collection.
Room temperature (only). Transport immediately. Do not refrigerate.
Stable 30 minutes at room temperature.
Stability limits exceeded. Specimens containing large clots or air bubbles.
