Thyroglobulin Antibody and Thyroglobulin Blood Test, IMA or RIA
The Thyroglobulin test is primarily used as a tumor marker to evaluate the effectiveness of treatment for thyroid cancer and to monitor for recurrence.
Description
Thyroglobulin measurement is intended to aid in monitoring for the presence of orthotropic and/or metastatic thyroid tissues in patients who have had thyroid gland ablation using thyroid surgery with or without radioactivity. Measurement of thyroglobulin antibody is used to identify patient samples that may be affected by TgAb interference in the measurement of Tg. Quantitative TgAb concentrations can also serve as a surrogate tumor marker for Differentiated Thyroid Cancer recurrence and for monitoring changes in tumor mass in certain patients.
