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 an RIA method. This RIA is resistant 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.
