    Collection
    Label the tubes according to your standard operating procedure, making sure that each tube has at least two unique patient identifiers. Draw 9 tubes, 11 mL serum in a red-top tube (no gel). Allow the blood to clot for at least 30 minutes, but not longer than 1 hour before centrifugation. Centrifuge each tube for 15 minutes at 1250 to 1600 RCF. Transfer serum to plastic screw-cap vial(s). The plastic screw-cap vial containing serum must be labeled with the specimen type. Place sample(s) on cold packs or in refrigerator. Sample is stable for 7 days at 2-8° C (refrigerated). Do not transport or store samples at room temperature.

We compile this page from named laboratory catalogs, guidelines and studies. Labs calculate reference intervals from the people they test, for one assay method and one population group, so an interval describes that population rather than an optimal target.
