Thyroid Antibodies (Thyroglobulin + TPO)
The Thyroid Antibodies test measures antibodies directed against components of the thyroid gland,
including Thyroglobulin antibodies (TgAb) and Thyroid Peroxidase antibodies (TPOAb). These antibodies
are produced when the immune system mistakenly targets thyroid tissue, leading to autoimmune thyroid disease.
Autoimmune thyroid disorders are among the most common endocrine conditions and include Hashimoto’s thyroiditis
and Graves’ disease. Measuring thyroid antibodies helps clinicians identify immune-related causes of thyroid
dysfunction even when standard hormone tests appear borderline or inconclusive.
The presence of thyroid antibodies may indicate inflammation or progressive damage to thyroid tissue,
which can eventually lead to hypothyroidism or, less commonly, hyperthyroidism.

Clinical Significance
Autoimmune thyroid disease occurs when the body’s immune system attacks the thyroid gland.
In Hashimoto’s thyroiditis, antibodies gradually destroy thyroid tissue, reducing hormone production.
In Graves’ disease, immune activity stimulates excessive hormone production.
Detecting antibodies early can help identify individuals at risk of developing thyroid dysfunction.
Thyroid antibody testing is particularly useful in individuals with unexplained thyroid hormone abnormalities,
family history of autoimmune disease, or symptoms suggestive of thyroid disorders.
Who Might Benefit From This Test?
This test may be recommended for individuals experiencing symptoms such as fatigue, weight changes,
hair thinning, mood changes, cold intolerance, or irregular menstrual cycles. It may also be used in
patients with abnormal TSH results or a family history of thyroid disease.
Pregnant women or individuals planning pregnancy may also be tested, as thyroid antibodies can influence
pregnancy outcomes and thyroid function during gestation.
Sample Collection
A simple blood sample is collected by a trained healthcare professional.
The sample is analysed in a specialist laboratory using immunoassay methods
to detect thyroid-specific antibodies.
Understanding Your Results
Positive antibody results indicate autoimmune activity affecting the thyroid gland.
However, some individuals with antibodies may still have normal thyroid hormone levels.
Regular monitoring may therefore be recommended to track potential progression
toward thyroid dysfunction.
