What Is The Thyroglobulin Antibodies Test For?

Thyroglobulin is a protein made and used in the thyroid gland. Its function is to make the two crucial thyroid hormones triiodothyronine (T3) and thyroxine (T4).

Since thyroglobulin occurs naturally in the body, usually your immune system does not produce high levels of antibodies against it (Thyroglobulin antibodies - TGAB). However autoimmune diseases can cause high levels of thyroglobulin antibodies resulting in disorder of the thyroid gland - both overactive and underactive thyroid disorders may develop as a result.

How To Test Thyroglobulin Antibodies

By buying a laboratory test kit with professional nurse or clinic collection, you can accurately measure Thyroglobulin Antibodies for total reassurance.

Professional analysis in an accredited laboratory ensures rapid result delivery.

The Vitall Thyroid Function & Autoimmune Reaction nurse or clinic test kit includes a Thyroglobulin Antibodies test and is available for just £89.00.

What if Thyroglobulin Antibodies Results Are High?

It is possible for thyroid antibodies to be detectable even in people who are otherwise healthy. Their presence tends to increase with age and is more common in women.

Mild to moderately elevated TGAB levels can be seen in a variety of diseases. In thyroid autoimmune diseases, TGAB concentrations are often much higher, and higher TGAB levels are generally associated with a greater likelihood of autoimmune thyroid disease being present.

TGAB is commonly interpreted alongside other thyroid function tests, including T4, T3, and TSH. When these results are normal and suggest normal thyroid function, an elevated TGAB may be less significant. When thyroid function tests are abnormal, an elevated TGAB is often reviewed further to clarify the cause.

What if Thyroglobulin Antibodies Results Are Low?

This is usually a normal result. However, in some individuals with symptoms linked to abnormal thyroid function or with abnormal thyroid function test results, other antibodies can be involved in autoimmune thyroid disease even when this antibody level is low.

Low levels of TGAB can be normal. This is generally considered a reassuring finding and is not usually linked to any specific next steps on its own.
