Sample collection instructions:
1. Centrifuge the sample
2. Within 2 hours of collection: Pour off, or aliquot using plastic pipet, serum into "Serum Transfer Tube" or alternate metal-free aliquot tube (example: "Mayo Metal-Free Plastic Aliquot Vial") (do not use glass pipettes, etc.)
Important Notes / Information: Serum or plasma should be removed from the cells within 2 hours of collection. Do not use glass pipettes or aliquot tubes, rubber stoppers, wood applicator sticks (for rimming clots), etc. as these may contaminate the specimen! If absolute necessary to rim for clots, only use a plastic pipet to minimize potential sample contamination. All collection and transfer tubes can be requested/ordered from Marshfield Labs.
Marshfield Labs serum transfer tubes have been validated to be metal-free and can be used for this test.
