An anti-thyroglobulin antibody is a type of antithyroid antibody that targets the thyroglobulin protein found in the thyroid gland. The presence of these antibodies can be detected through an anti-thyroglobulin antibody test, & elevated levels of anti-thyroglobulin antibodies may indicate autoimmune thyroid disorders, including Hashimoto's thyroiditis or Graves' disease.

Regular monitoring of these antibodies can contribute to effective management strategies and improved patient outcomes.

Why Do I Need an ATG Test?

An ATG test is required for individuals experiencing thyroid-related symptoms such as:

  • Extreme fatigue and weakness
  • Sudden and unexplained weight gain or loss
  • Severe constipation
  • Excessive dry skin

The test allows for the detection of anti-thyroglobulin antibodies and aids in accurate diagnosis and treatment planning, and monitoring of thyroid health.

What Does Anti-Thyroglobulin Antibody Test Measure?

An anti-thyroglobulin antibody test is a diagnostic tool used to measure the levels of anti-thyroglobulin antibodies in the bloodstream. These antibodies specifically target the thyroglobulin protein present in the thyroid gland.

How To Prepare For Anti-Tg Antibody Test?

There are no special preparations needed when getting an ATG test. In certain cases, the healthcare provider might want you to fast (not consume any food for a few hours) before the test.

What Happens During Antithyroid Antibody Testing?

An antithyroid antibody test only takes a few minutes

  • As per the scheduled time of the blood test, a lab technician who usually takes blood samples will arrive.
  • A thin needle will be used to draw blood from your arm’s vein.
  • The needle might cause a mild pinch and some discomfort.
  • The lab technician then fills a collection tube with blood and then removes the needle from the skin.
  • They place a small bandage on the arm.

Should you call for the ATG test at home to check your thyroglobulin levels or get it done at your nearest clinic? Continue reading to know more. 

Can I Take Anti TG Test At Home?

How Much Does Anti-TG Test Cost?

The anti-thyroglobulin antibody test price varies depending on various factors, such as where you live, the healthcare provider or a laboratory that performs the test, and whether or not you have health insurance coverage. You can check the anti-tg test price on our website. We offer this test at INR 987. Our prices are lower than the average test prices without compromising on quality.

What Is the Anti-Thyroglobulin Antibody Normal Range?

The normal range for anti-thyroglobulin antibody levels can vary depending on the laboratory and testing method used. However, the anti-tg normal range is less than 116 IU/mL.

What Medical Conditions Can Cause High Thyroglobulin Antibody Levels?

Curious about what causes high thyroglobulin levels? Certain medical conditions can lead to elevated thyroglobulin levels.

  • Virus infection of the ear, sinus, or throat:  Infections caused by certain viruses, such as Epstein-Barr virus (EBV) or human herpesvirus 6 (HHV-6), have been linked to an increased risk of autoimmune thyroid diseases. These infections can trigger an immune response, including the production of thyroglobulin antibodies.
  • Large quantities of iodine intake: Increased levels of thyroglobulin antibodies can occasionally occur as a result of excessive iodine intake, whether from food or medicine. Individuals with underlying autoimmune thyroid problems are more likely to experience this.
  • Destruction of thyroid follicles caused by thyroid nodules: Thyroid follicles in the area may be destroyed by thyroid nodules, especially if they are autonomous or hyperactive. Thyroglobulin may be released into the bloodstream as a result of this breakdown, inducing an immunological response and the development of thyroglobulin antibodies.
  • Cancer: Thyroglobulin antibody levels can be elevated in certain types of thyroid cancer, such as papillary and follicular thyroid cancer. Monitoring these antibodies is important for detecting cancer recurrence or persistence.
  • Non-Thyroid Autoimmune Disorders: In some cases, elevated thyroglobulin antibody levels may be present in individuals with autoimmune disorders that are not directly related to the thyroid, such as type 1 diabetes and Sjögren's syndrome.
  • Chronic Lymphocytic Thyroiditis: This condition, also known as Hashimoto's thyroiditis, is characterized by chronic inflammation of the thyroid gland, leading to decreased thyroid hormone production. Elevated thyroglobulin antibody levels are commonly seen in individuals with this condition.

What Medical Conditions Can Cause Low Thyroglobulin Antibody Levels? 

Curious about what causes low thyroglobulin levels? Certain medical conditions can lead to low thyroglobulin levels.

  • Subclinical hypothyroidism: Some cases of subclinical hypothyroidism show low thyroglobulin antibody levels. It's a mild form of hypothyroidism with slightly elevated TSH and normal free T4 levels.
  • Absence of Thyroid Gland: Since the thyroid gland, which is the source of thyroglobulin production, has been surgically removed, people who have undergone total thyroidectomies often have low or undetectable levels of thyroglobulin antibodies.
  • Transient Thyroiditis: Thyroglobulin antibody levels may temporarily drop during the acute phase of transitory thyroiditis, which includes subacute thyroiditis or postpartum thyroiditis. This is because the thyroid gland is inflamed and damaged, which might interfere with the synthesis of antibodies.

FAQs Around Thyroid Antibody Test

The thyroglobulin level indicating cancer depends on various factors. Generally, values under 1 ng/mL are normal. Levels of 1-10 ng/mL should be assessed in conjunction with cytology results, and levels above 10 ng/mL suggest the presence of malignancy.

If thyroglobulin antibody levels are high, it could indicate various thyroid-related conditions such as Hashimoto's Thyroiditis, Graves' Disease, Postpartum Thyroiditis, Thyroid Cancer, Subacute Thyroiditis, Autoimmune Polyglandular Syndrome, Idiopathic Myxedema.

After a thyroidectomy, the ideal thyroglobulin levels should be <0.2 ng/mL for non-stimulated thyroglobulin and <1 ng/mL for stimulated thyroglobulin in the absence of interfering antibodies.

Reducing thyroglobulin antibodies naturally is not guaranteed, as they are a result of autoimmune processes. However, adopting a healthy diet, addressing gut health, and considering targeted supplementation may be beneficial.
