This test detects antibodies that target thyroglobulin, which can interfere with thyroglobulin measurements and indicate autoimmune thyroid disease.
Diagnostic Value: The presence of Tg antibodies helps identify autoimmune thyroiditis (Hashimoto’s disease) and can affect interpretation of thyroglobulin tumor marker levels.
Clinical Significance: Detecting Tg Ab II is vital for accurate cancer monitoring and distinguishing between antibody interference and true thyroglobulin elevation.
Symptom Correlation: Patients may experience fatigue, swelling in the neck, or gradual thyroid failure consistent with autoimmune thyroid conditions.
The Tg Ab II test ensures accurate thyroglobulin interpretation and supports autoimmune thyroid disorder diagnosis.
