Thyroglobulin Antibodies (Anti TG) Test

Thyroglobulin Antibodies (Anti TG) Test Description

The Thyroglobulin Antibodies (Anti TG or TgAb) test measures the presence of antibodies targeting thyroglobulin, a protein produced by the thyroid gland. These antibodies can indicate autoimmune thyroid diseases where the immune system attacks thyroid tissue, such as Hashimoto’s thyroiditis or Graves’ disease.

Indications of the Test

This test is commonly ordered to help diagnose autoimmune thyroid conditions, monitor thyroid disorders, and sometimes to support the diagnosis of thyroid cancer or thyroid gland damage. It is useful when symptoms like thyroid inflammation, goiter, or abnormal thyroid hormone levels are present.

Patient Preparation/Instructions

Before the test, patients should avoid taking multivitamins or supplements containing biotin (vitamin B7) for at least 12 hours prior, as these can interfere with the test. The test requires a simple blood draw, with no major fasting or other preparations necessary.

Typical Reference Values

Normal reference values for thyroglobulin antibodies are usually below 20 IU/mL, although ranges can vary by laboratory. Low or undetectable levels are normal; elevated levels suggest an autoimmune response affecting the thyroid.

Time to Get Report

Results for the Thyroglobulin Antibodies test typically take between 1 to 3 days to be processed and reported by the laboratory.
