Positive for thyroid paroxidase antibodies and thyroglobulin antibodies. What does this mean? Had pap thyroid cancer in 2008 with thyroidectomy

Positive for thyroid paroxidase antibodies and thyroglobulin antibodies. What does this mean? Had pap thyroid cancer in 2008 with thyroidectomy

Immunity to thyroid: The thyroid makes thyroglobulin (tg) and thyroid peroxidase (tpo). Even though you had your thyroid removed, your body's immune system sees tg and tpo as foreign and has made antibodies to them. This means that following your tg as a way to monitor your thyroid cancer might be unreliable. It could also mean you have thyroid tissue that is still present in your body. Ask your endocrinologist! ...Read more

Cancer (Definition)

Cancer is a group of diseases that is characterized by uncontrolled cell growth leading to invasion of surrounding tissues that spread to other parts of the body. Cancer can begin anywhere in the body and is usually related to one or more genetic mutations that allow normal cells to become malignant by interfering with internal cellular control mechanisms, such as programmed cell death or by preventing ...Read more

I have hashimotos and I just got my bloodwork. Thyroglobulin is way high and I have no antibodies. Is this a sign I might have thyroid cancer?

I have hashimotos and I just got my bloodwork. Thyroglobulin is way high and I have no antibodies. Is this a sign I might have thyroid cancer?

See your doc: Thyroglobulin is only made by thyroid cells. All an elevated thyroglobulin tells you is that you have "something" going on with your thyroid. It could just be inflammation, but you can't know until more tests are done. This test is not a sensitive or specific test for diagnosing thyroid cancer. See an endocrinologist to find out more. ...Read more

Is it possible recurrence of thyroid cancer if thyroglobulin came back positive but antibodies are decreasing? Had full thyroidectomy 2 years ago.

Is it possible recurrence of thyroid cancer if thyroglobulin came back positive but antibodies are decreasing? Had full thyroidectomy 2 years ago.

Recurrence: Rest assured. It is impossible to say you are cancer free, but that is likely. Here's why: the thyroglobulin level is unreliable because you have antibodies. The fact that the antibodies are decreasing can mean that thyroglobulin is decreasing. Antibodies can be a tumor marker surrogate. Continue to follow the antibody trend and get periodic neck ultrasounds. ...Read more

I had a thyroglobulin antibody test taken and the results were 320. What does this mean? Should I be concerned about lupus, hashimoto's disease or thyroid cancer? I have been diagnosed with hypothyroid and the medicine I have been taking in addition to ve

Hashimoto's you have: You had become hypothyroid because you have hashimoto's thyroiditis, which was confirmed by the elevated thyroglobulin activity. You should not worry about lupus, or other conditions such as cancer. The strongest association with hashimoto's and another autoimmune problem is psoriasis and psoriatic arthritis. ...Read more

23 yrs old f; thyroid peroxidase 13 (norm); thyroglobulin, antibody 3.0 (high); TSH 10.850 (high); nomal T3 (liothyronine) & t4. Hashimotos? Possible thyroid cancer

Possible to 1st: Thyroglobulin is a test that is helpful after someone has surgery for the most common thyroid cancer. Thyroid function tests can test how well your thyroid is working. If there is concern for cancer it is helpful to get a thyroid ultrasound and then a biopsy if clinically indicated. ...Read more

If have thyroid cancer and my thyroglobulin continues to be high, should I see a cancer specialist?

If have thyroid cancer and my thyroglobulin continues to be high, should I see a cancer specialist?

Yes: If you have thyroid cancer, you should already have an endocrinologist and a thyroid surgeon on your team (and possibly a radiation oncologist also). They should work together to find the source of the elevated thyroglobulin. You might need radioactive iodine or repeat surgery. Good luck. ...Read more

Thyroglobulin tumor marker s value is 12. Is this normal? Have had thyroid cancer about 13 years ago

Thyroglobulin tumor marker s value is 12. Is this normal? Have had thyroid cancer about 13 years ago

See your doctor.: If you had total thyroidectomy and radioactivie iodine treatment, the thyroglobulin (Tg) should be undetectable or very low (< 0.5). If your Tg has been in this range in the past, having a level of 12 now would be concerning for regrowth of the thyroid cancer, OR normal thyroid tissue, if any survived the initial treatment. If you have antibodies to Tg, that can cause falsely high or low Tg levels ...Read more

Thyroglobulin was checked in april was. 6 I and a papillary thyroid cancer patient. When should I retest the tg?

Variable: Most patients get thyroglobulin checked every 12 months. Every 6 months if there is a worry. I think a trend of increasing levels would be more worrisome. You and your doctors may discuss getting a stimulated level as well as radioactive iodine scan by making you hypothyroid or some may feel getting these tests with thyrogen stimulation could be done. ...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

Positive anti-thyroglobulin (94 iu/ml), negative anti-thyroid peroxidase. Normal TSH levels. Thyroid autoimmune? Cancer? Feel mostly symptom free

No indication of: Cancer. From the information you provided, there is no reason to think you have cancer. You should have regular check ups, including thyroid function tests as you are at greater risk for developing thyroid deficiency. For good health - Have a diet rich in fresh vegetables, fruits, whole grains, milk and milk products, nuts, beans, legumes, lentils and small amounts of lean meats. Avoid saturated fats. Drink enough water daily, so that your urine is mostly colorless. Exercise at least 150 minutes/week and increase the intensity of exercise gradually. Do not use tobacco, alcohol, weed or street drugs in any form.
Practice safe sex, if you have sex. ...Read more

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

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

My blood test showed an elevated level of tg antibodies. Does that mean I have cancerous cells running around? Had papillary thyroid cancer a year ago

Not necessarily.: Having elevated tg antibodies primarily means that the more important tg test itself will be falsely lower than its true value. (no conversion formula exists.)

if your tg antibodies are only 20 or so, with an undetectable tg level, it is hard to know what that means. If your tg antibodies are much higher, then concern for the presence of thyroid cancer would increase. ...Read more

What does it mean when thyroid peroxidase antibodies 50.2 IU/mL? Thyroglobulin antibodies 18.0 IU/mL?

Not much by itself: Thyroid antibodies are most helpful if you have a low free T4 and a high TSH indicating hypothyroidism which is most often due to autoimmune thyroid inflammation. If those tests are normal you need no treatment but your high antibodies suggest you have an increased risk of developing hypothyroidism somewhere down the road, but many people with antibodies never develop a thyroid problem. ...Read more

Need to examine: All laboratory results need to be interpreted in the clinical context and the doctor who ordered the tests is usually in the best position to do that.
It is not feasible to provide a meaningful opinion without taking additional history, physical examination and may be some tests. It would be prudent to see your doctor and discuss the findings with him/her. ...Read more

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

Is thyroiditis (based on u/s that showed borderline thyroid enlargement /goiter) related to thyroid cancer? If no nodes were seen? Have globus symptom

Globus: You started with a globus sensation which may be due to an anxiety disorder. You had a thyroid U/S done which sounds to be NORMAL. Thyroiditis is not diagnosed on ultrasound, its based on hormone levels. You have no goiter or nodules. You have a normal exam. You need to address the globus. You can get an ENT exam with laryngopharyngoscopy and talk to your doctor about treating anxiety or OCD. ...Read more

Thyroglobulin Antibodies (Definition)

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 ...Read more
