WebbOver recent years, it has become clear that thyroglobulin assays need second-generation functional sensitivity in order to monitor the low basal (non-TSH stimulated) thyroglobulin concentrations arising from the intact surgical remnant of low-risk DTC patients who no longer receive routine RAI remnant ablation. Webbgeneration assay with a functional sensitivity of 0.9ng=mL (mg=L) failed to reliably detect an rhTSH-Tg response above 2.0ng=mL (mg=L). Conclusions: An rhTSH-Tg response above 2.0ng=mL (mg=L) was highly unlikely when b-Tg was below 0.1ng=mL (mg=L). Second-generation b-Tg measurements correlated with the degree of rhTSH-Tg …

"Thyroglobulin (Tg) is a storage form of thyroxine (T4) and triiodothyronine (T3). It is synthesized only by thyroid follicular cells and released into serum along with the thyroid hormones. Given the cellular specificity of Tg, its detection in biopsy specimens provides proof of the thyroid origin of the tissue. " - Thyroglobulin beckman second generation
