About this test
The anti-thyroid antibody test detects autoantibodies that attack the thyroid gland, usually anti-TPO (thyroid peroxidase) and anti-thyroglobulin (anti-Tg) antibodies.
A normal result is negative, below the lab’s cut-off value.
Positive antibodies confirm autoimmune thyroid disease, mainly Hashimoto’s thyroiditis, the most common cause of hypothyroidism, and Graves’ disease. They also predict whether mild (subclinical) hypothyroidism may progress, and identify women at risk of postpartum thyroiditis.
In pregnancy, positive antibodies are linked to miscarriage and preterm birth risk, guiding closer monitoring.
Questions about this test
When should I get the Anti Thyroid Antibody test?
You should get an anti-thyroid antibody test if you have abnormal TSH or thyroid hormones, a goiter, or symptoms such as fatigue, weight changes, hair loss, palpitations, or cold or heat intolerance. It is also recommended for infertility, recurrent miscarriage, pregnancy planning, other autoimmune diseases, and a family history of thyroid disease.
How should I prepare for the Anti Thyroid Antibody test?
No special preparation or fasting is required for an anti-thyroid antibody test. Stop biotin supplements 48–72 hours beforehand, as biotin may interfere with results. Inform your doctor about any thyroid medicines, pregnancy, recent childbirth, or radioactive iodine treatment. Bring previous thyroid function test reports if available.
Do I require fasting for the Anti Thyroid Antibody test?
No, fasting is not required for an anti-thyroid antibody test. You can eat and drink normally before giving your sample, and the test can be done at any time of day. However, stop biotin supplements 48–72 hours beforehand, as biotin may interfere with the results.
