تست Thyroglobulin

Intact Thyroid : 3.5 - 77
-According to pagana reference: The Thyroglobin levels will be low (<2ng.ml) or undetectable after treatment (usually surgery followed by radioactive lodine).
-It has been determined that the presence of antithyroglobulin autoantibodies (TgAb) in serum can lead to underestimation of Tg concentration by immunometric methods. When TgAb are present in samples with detectable Tg, the Tg values may be underestimated by up to 60% in immunoassays. In addition, approximately 20% of specimens containing TgAb, which are negative for Tg by immunoassay, tested positive by liquid chromatography-tandem mass spectrometry (LC-MS.MS). Therefore, measuring of Tg by mass spectrometry is the preferred method in TgAb positive patients.
