Antithyroglobulin Antibody Test

The thyroid gland causes the release of hormones that regulate your metabolism. It generates a variety of proteins, including thyroglobulin. Thyroglobulin is used by the thyroid gland to produce active thyroid hormones.

An autoimmune disorder can interfere with the generation of thyroglobulin. When your immune system produces antibodies which attack the body's own healthy cells, you have an autoimmune disorder. When the immune system attacks the thyroid, it frequently affects thyroglobulin. As a result, it produces antithyroglobulin antibodies. An antithyroglobulin antibody test can be ordered by your doctor to determine the amount of these antibodies in your circulation. A high level might suggest an autoimmune disorder.

What is the purpose of an antithyroglobulin antibody test?

If you experience symptoms of a thyroid issue, your doctor may prescribe an antithyroglobulin test. The following are the symptoms:

  • Unexplained weight gain
  • Tiredness
  • Constipation
  • Scaly skin

Your doctor may also prescribe it if you develop a goiter, a disease in which your thyroid gland enlarges. Doctors may also order it if they believe you have Graves' disease or Hashimoto thyroiditis. It can aid in the detection of thyroid dysfunction.


How should you prepare for the examination?

You will need to get a blood sample collected for an antithyroglobulin antibody test. The doctor will instruct you on how to prepare. They may request that you refrain from eating or drinking for several hours prior. They may also request that you discontinue taking any drugs that may interfere with your test findings or blood draw. They may, for example, encourage you to refrain from taking blood thinners such as warfarin or even multivitamins.

Inform your doctor about any medications you use, including prescription and over-the-counter medications. Do not discontinue your prescriptions without first consulting your doctor.


How is the examination conducted?

A nurse or lab technician will extract a blood sample from you. They will most likely draw it from a vein in your arm using a tiny needle. They will collect blood samples in a tube and transport it to a lab for analysis. When your test results are ready, your doctor will notify you.


What are the risks associated with the test?

This test poses no risks or dangers. Some people may feel discomfort when the blood is extracted. The area may cause a little discomfort, throbbing, or bruising after the needle has been inserted, but most effects will go soon.


What do the test findings mean?

The normal outcome for this test is "negative." If you get negative findings, it signifies that no antithyroglobulin antibodies were detected in your blood sample. If you have modest levels in your blood, it might indicate a number of health issues, including:

If there are high levels of antithyroglobulin antibodies in your blood, it might be a symptom of a dangerous autoimmune condition like Graves' disease or Hashimoto thyroiditis.

You might have antithyroglobulin antibodies in your blood without any particular issues in certain circumstances. If your test shows positive results for these antibodies and the doctor is unable to determine the underlying reason, you may be monitored for emergent health concerns.

Your doctor can assist you in comprehending the findings of your test. Your recommended next steps will be determined by your unique diagnosis. They may, for example, suggest additional testing or treatment choices. Inquire with your doctor about your test findings, condition, and future prevention steps.
