O ensaio de tiroglobulina com melhor sensibilidade funcional enquanto os pacientes tomam L-T4 substituirá a tiroglobulina estimulada pelo TSH no seguimento dos pacientes com câncer diferenciado da tiróide?

The author reviews the literature on the new assays for serum thyroglobulin (sTg) presenting lower functional sensitivity and demonstrates that its use, whilst the patients are taking L-T4, presents better results than sTg following TSH stimulation in the follow-up of patients with differentiated th...

Sumario:The author reviews the literature on the new assays for serum thyroglobulin (sTg) presenting lower functional sensitivity and demonstrates that its use, whilst the patients are taking L-T4, presents better results than sTg following TSH stimulation in the follow-up of patients with differentiated thyroid carcinoma. Therefore, he suggests a revision on the guidelines for the follow-up of these patients (developed when the available assays present a sensitivity of 1 ng/mL), proposing the use of sTg assays with functional sensitivity of 0.1-0.2 ng/mL with the patients on L-T4 treatment instead of sTg stimulated by TSH.
