Ranges

Each lab publishes a reference range for the population groups it tests, usually the middle 95% of results. These intervals describe that population, not an optimal or healthy target. How ranges differ

  • Chronic Urticaria Panel 1 16440

    Method and collection
    Method
    See individual tests
    Preparation
    Patients taking calcineurin inhibitors should stop their medication for 72 hours prior to draw. Specimen collection after fluorescein dye angiography should be delayed for at least 3 days. For patients on hemodialysis, specimen collection should be delayed for 2 weeks after angiography. According to the assay manufacturer Siemens: samples containing fluorescein can produce falsely depressed values. Dietary supplements containing biotin may interfere in assays and may skew results to be either falsely high or falsely low. For patients receiving the recommended daily doses of biotin, draw samples at least 8 hours following the last biotin supplementation. For patients on mega-doses of biotin supplements, draw samples at least 72 hours following the last biotin supplementation.

  • Thyroglobulin Antibody 006685

    Serum · Fasting not stated · Turnaround 1 - 3 days

    Method and collection
    Method
    Immunochemiluminometric assay (ICMA). This assay is performed using Beckman Coulter Methodology in multiple laboratories throughout Labcorp.
    Collection
    Separate serum from cells, and transfer specimen to a plastic transport tube.

  • Thyroglobulin Antibody and Thyroglobulin, IMA or LC/MS-MS 042045

    Serum · Fasting not stated · Turnaround 1 - 5 days

    Method and collection
    Method
    TgAb: Beckman Coulter immunometric assay; Tg-IMA: Beckman Coulter immunometric assay; Tg: Liquid chromatography/tandem mass spectrometry (LC/MS-MS) lab-developed test. Both Tg assays are calibrated against CRM-57 international standard for Tg as recommended in recent guidance documents.1 LabCorp uses a dual Tg strategy in an effort to eliminate the potential effect of TgAb interference on Tg analysis. All specimens are initially assayed for TgAb by the highly sensitive Beckman Coulter IMA. Samples with TgAb below the detectable limit are assayed for Tg by a sensitive second-generation IMA (Beckman Coulter) with a relatively rapid turnaround time. Specimens with any measurable levels of TgAb are assayed by a sensitive LC/MS-MS method.
    Collection
    Separate serum from cells, and transfer specimen to a plastic transport tube.

  • Thyroglobulin Antibody and Thyroglobulin, IMA or RIA 042060

    Serum · Fasting not stated · Turnaround 1 - 4 days

    Method and collection
    Method
    Immunometric assay (IMA and radioimmunoassay (RIA); Anti-Tg: Beckman Coulter immunometric assay; Tg IMA: Beckman Coulter immunometric assay; Tg RIA: Lab-developed radioimmunoassay LabCorp uses a dual Tg test strategy in an effort to minimize the potential effect of TgAb interference on Tg analysis. All specimens are initially assayed for TgAb by the highly sensitive Beckman Coulter IMA. Samples with TgAb below the detectable limit are assayed for Tg by a sensitive second-generation IMA (Beckman Coulter) with a relatively rapid turnaround time. Specimens with any measurable levels of TgAb are assayed by an RIA method performed at Endocrine Sciences, Calabasas Hills, Calif. This RIA is resistant to interference by TgAb but has a longer turnaround time of five to seven days.
    Collection
    Separate serum from cells, and transfer specimen to a plastic transport tube.

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.
