Diagnostic Blood Test:

  • Thyroglobulin Antibody (TgAb) Thyroglobulin, IMA or RIA

Thyroglobulin antibody (TgAb) testing is performed. If TgAb is negative, serum thyroglobulin is measured by a sensitive IMA. If TgAb is positive, serum thyroglobulin is measured by a sensitive LC/MS-MS method. This method is less prone to interference by TgAb.

Note: This test may exhibit interference when sample is collected from a person who is consuming a supplement with a high dose of biotin. Cease biotin supplementation at least 72 hours prior to blood draw.
