Web30 mei 2024 · H 2 O 2 is required for the TPO-mediated oxidative iodination of tyrosine residues of thyroglobulin (TG), which will further allow T3 and T4 synthesis . Dual-oxidase 2 (DUOX2), a member of the NADPH oxidase family, localized on the apical membrane of thyrocytes, is the source of H 2 O 2 required for hormonal biosynthesis [31,32,33,34]. Thyroglobulin levels are tested via a simple blood test. Tests are often ordered after thyroid cancer treatment. Thyroglobulin antibodies. In the clinical laboratory, thyroglobulin testing can be complicated by the presence of anti-thyroglobulin antibodies (ATAs, alternatively referred to as TgAb).
