Thyroglobulin Antibodies (Overview)

Thyroglobulin antibodies are proteins made by the immune system. The immune system is recognizing the thyroid as strange to the body. Thus, this is a marker of autoimmune thyroid disease. It is usually measured to confirm hashimoto's thyroiditis, but can be seen in people without significant thyroid pathology and with normal thyroid levels. It can also be seen with any autoimmune thyroid disease.

Tt papillary cancer and hurtle cell. Recent blood work TSH. 59 total T3 (liothyronine) 64.7. Free T4 1.5. Thyroglobulin antibodies 1.5 what does that mean?

Thyroid cancer: Your dose of synthroid (thyroxine) should be adjusted such that your TSH is suppressed, and yours is about right, although your endocrinologist may increase your dose slightly. Thyroglobulin is a marker of recurrent cancer, but thyroglobulin antibodies can interfere with the assay. This is complicated. You need to discuss all of this with your endocrinologist. ...Read more

Read this on my lab report "low positive thyroglobulin antibodies are seen in assymptomatic population" what does that mean in real terms?

Not diagnostic: In general, lab tests are used to support a clinical diagnosis and thus a positive test per se does not provide a diagnosis without abnormal physical findings or symptoms. On many occasions, an abnormal lab test is not associated with any disease condition especially when the value is only slightly abnormal. If you do hundreds of tests on a healthy person, you will likely find something abnormal. ...Read more

Negative result for thyroid peroxidase antibodies tpoab. Necessary to test my thyroglobulin antibodies tgab?

Anti-thyroglobulin: Studies have shown that 99% of patients with hashimoto's thyroiditis have anti-microsomal antibodies, whereas only about 1/3rd had anti-thyroglobulin antibodies. In addition, 10-20% of persons without thyroid problems have anti-throglobulin antibodies (tg-a). These persons are likely at higher risk for future problems and should be watched more closely however, testing for tg-a is not necessary. ...Read more

Not well, enlarged thyroid, two benign nodules that are autonomous, TSH low, T4 low end of normal, thyroglobulin antibodies present - thoughts?

Suggests autoimmune: Your symptoms and lab values suggest an autoimmune inflammatory problem. You need expert evaluation and should see a qualified doctor as soon as possible. Doctors that specialize in thyroid disorders are endocrinologists. However, many medicine doctors from family medicine and internal medicine are very adept at helping with thyroid disease. ...Read more

Why would a hylanizing traebuler adenoma make thyroglobulin antibodies if its benign?

Why would a hylanizing traebuler adenoma make thyroglobulin antibodies if its benign?

It doesn't: You most likely already had tg antibodies before the hyalinizing trabecular adenoma diagnosis is given. Many people has autoimmune thyroid disease with tg antibodies in the background. This has nothing to do with benign or malignant potential although it could cause some problems following thyroglobulin level in the future. ...Read more

Is there any natural homopathic ways to lower my thyroglobulin antibodies in order to get an accurate thyroglobulin?

Is there any natural homopathic ways to lower my thyroglobulin antibodies in order to get an accurate thyroglobulin?

Unfortunately, no: Hi. It appears you've had treated differentiated thyroid cancer, and your thyroglobulin can't be monitored because of interfering thyroglobulin antibodies (Tg Ab's). Unfortunately, there is no way to lower Tg Ab's. "Natural homeopathic" is fine for the worried well, but not for real disease. Stick to real medicine shown to be safe and effective. There is no real medicine way to lower Tg Ab's. ...Read more

My thyroglobulin antibodies level was high on my blood test. What does this mean?

Autoimmune: These antibody titers point to the presence of an autoimmune process which makes you at a higher risk of getting thyroid disease.

Immune binding of t: This is an immune reaction to bind thyroid hormone in or out of the cell. It can be caused by a lot of different conditions including pregnancy, other autoimmune conditions or primary thyroid disease or virus infections. It's importance for future thyroid disease depends on what is going on with you clinically at this time. ...Read more

Does an elevated level of thyroglobulin antibodies and calcitonin mean cancer?

Does an elevated level of thyroglobulin antibodies and calcitonin mean cancer?

Elevation.: Thyroglobulin autoantibodies can be present in benign/malignant thyroid disease. If you have a diagnosis of papillary or follicular cancer, their presence can interfere with thyroglobulin as a tumor marker. If autoantibodies rise, that can be a surrogate marker for cancer recurrence. As for calcitonin, it's elevation is clinically significant in cases of primary or recurrent medullary cancer. ...Read more

Should I be worried if my thyroglobulin antibodies level is 1906 and my TSH is 1.25?

Should I be worried if my thyroglobulin antibodies level is 1906 and my TSH is 1.25?

No worry: Hi. Your thyroid is experiencing some autoimmune reaction (usually an attack), but is maintaining normal function. The thyroglobulin antibodies (and TPO antibodies also) mark the autoimmune process, but do not themselves cause any harm to the thyroid (or anything else). This is usually called euthyroid Hashimoto's. No treatment is warranted until your TSH (+/- free T4) becomes abnormal. Good luck! ...Read more
