    3 analytes · Serum · Fasting not stated

    Method and collection
    Method
    Immunoassay (IA) • Mass Spectrometry (MS)
    Preparation
    Samples should not be collected from a patient who has received vitamin B12 injection therapy within the past week.
    Collection
    Do not expose specimen to light for more than 24 hours. Note: Send serum in an amber tube. If amber tube is not available, wrap tube in aluminum foil to protect from light. Separate serum into three tubes, 1 tube with 2 mL and 2 tubes with 1 mL each. Red-top tube (preferred): Centrifuge the specimen as soon as possible after complete clot formation has taken place. Transfer the serum to a plastic screw-capped vial and ship it at refrigerated temperature. Barrier gel separator tube (acceptable): Centrifuge the specimen as soon as possible after complete clot formation has taken place. Do not place barrier tubes in an ice bath as freezing may prevent the barrier gel from adequately separating serum from cells. Transfer the serum to a plastic screw-capped vial and ship it at refrigerated temperature. Heparin tube (acceptable): Centrifuge the specimen as soon as possible (within one hour after collection) and transfer the plasma to a plastic screw-capped vial and ship it at refrigerated 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.
