For patients who were treated with a total thyroidectomy and adequate I-131 ablation, there is no “normal” range of serum thyroglobulin values; any measurable thyroglobulin is considered sufficient evidence for persistent thyroid carcinoma.

processes, involving vesicles laden with thyroglobulin moving into and out of the cells, are somehow regulated so that under normal circumstances thyroglobulin neither accumulates in follicular cells nor are the lumens depleted. The physiological mechanisms for such traffic control are not yet understood....
Serum thyroglobulin was undetectable in one patient, low normal in another and in the normal range for the third one. Except for the patient with undetectable Tg the two other subjects slightly increased the serum Tg levels after a bovine TSH injection. Plasma chromatography after a tracer dose ...
Struma ovarii (SO), also known as ovarian goiter, is a mature teratoma of the ovary that contains predominantly (>50%) or exclusively thyroid tissue [56]. Thyroid tissue can be detected in 5–20% of mature teratomas [56]. SO can be a rare cause of thyrotoxicosis, with up to 8% of...
The median T/B ratio of lesions detected by99mTc-3PRGD2 SPECT/CT was 4.8 (range 1.4–13.2) in 30 patients with positive uptakes. We did not detect any lineal correlations between serum sTg levels and the T/B ratio in these patients (r = 0.280,P = 0.246). However, when we...
Physiologically, Tg is released in small amounts from the thyroid. It is estimated that 1 g of tissue corresponds to 1 μg/Lserum Tgifserum TSHis in the normal range. Disruption of the normal thyroid structure results in leakage of Tg, and high serum levels are found in goitrous patients...

TSH should be lowered to below normal in patients with active disease. If patients are clinically disease free with Tg levels below 2 ng/mL, TSH can be kept within the normal range. For the most controversial group B patients, it is recommended that the TSH be suppressed and be closely ...
Conversely, the total T3 or T4 rate can be reduced by a reduction in the rate of the bonding proteins, and this might lead to a diagnosis of hypothyroidism, although the rate of free T3 or T4 is normal. It is therefore preferable to be able to determine the rates of free T3 or T4...
