Tsh Antibody (Overview)

A thyroid-stimulating hormone (TSH) blood test is used to check for thyroid gland problems. Tsh is produced when the hypothalamus releases a substance called thyrotropin-releasing hormone (trh). Trh then triggers the pituitary gland to release tsh. See pictures of the thyroid gland and the pituitary gland

Low free t3, (liothyronine) normal TSH and high tpo antibodies. What's this mean?

Low free t3, (liothyronine) normal TSH and high tpo antibodies. What's this mean?

Probable hypothyroid: The free t4, not free T3 (liothyronine) test, is necessary here. Positive antibodies indicate hashimoto's thyroiditis, the most common cause of hypothyroidism. It may just be early in the process to cause the TSH to be elevated. ...Read more

Can you have low TSH with Hashimoto's (antibodies are present)?

Can you have low TSH with Hashimoto's (antibodies are present)?

Yes, transiently: Hashimoto's thyroiditis can go through a phase of thyroid hyperactivity early in the course of disease and that would be associated with low TSH. Sooner or later enough thyroid is destroyed that thyroid functions declines and TSH rises. ...Read more

Is it possible for free T3 (liothyronine) & reverse T3 (liothyronine) tests turn up as a thyriod problem if you TSH & antibodies are normal?

Is it possible for free T3 (liothyronine) & reverse T3 (liothyronine) tests turn up as a thyriod problem if you TSH & antibodies are normal?

"thyroid problem": The blood tests help, but you need to correlate test with symptoms and you need a doctor who can help you put this in perspective (eg. An endocrinologist). If TSH and ft4 is normal, the thyroid is likely functioning normally. Free t3 (liothyronine) and rt3 (liothyronine) can be affected by a chronic illness (eg renal failure, inflammatory bowel, etc). ...Read more

I just got my thyroid test and noticed my thyroglobulin Ab <20 and Peroxidase =201.. TSH receptor antibody 1.6 .. what does that signify ??

I just got my thyroid test and noticed my thyroglobulin Ab <20 and Peroxidase =201.. TSH receptor antibody 1.6 .. what does that signify ??

See your physician: You don't tell us what your thyroid function tests showed. You have autoantibodies - antibodies that our immune system produces against our own thyroid gland. You probably have thyroid disease and see your current physician first. You may have to see an endocrinologist, a physician who specializes in the diseases of the endocrine system. ...Read more

I have thyroid nodule measuring 29×20 mm in size usg report indicate a hyperechoic structure with increased vascularity my TSH n antibody normal?

Indeterminate nodule: Hyper-echoic nodule has 5% chance of malignancy and the risk increases with large dominant nodule. 20-30% of all cancers are iso/hyper-echoic. Since this big nodule will be easy to biopsy - tissue diagnosis may be obtained to exclude malignancy. ...Read more

Dx'd hypothyroid (TSH 28,negative antibodies) at 10y/o and on Levothyroxine since. Tested again and still neg antibodies. What could be cause of hypo?

Dx'd hypothyroid (TSH 28,negative antibodies) at 10y/o and on Levothyroxine since. Tested again and still neg antibodies. What could be cause of hypo?

Many possibilities: Hypothyroidism is very common but in most cases the cause isn't known. There are many possible causes.There are genetic tendencies and it's also related to iodine deficiencies and exposure to many environmental toxins including fluoride, BPA, pesticides, a diet high in goitrogenic foods etc. It is difficult to determine in an individual case.

6 months postpartum low TSH and thyroid antibodies found.Tsh went back to normal 2 months later. Hashimotos? Or just postpartum thyroiditis?

6 months postpartum low TSH and thyroid antibodies found.Tsh went back to normal 2 months later. Hashimotos? Or just  postpartum thyroiditis?

Probably: Postpartum, but doesn't really matter if lab returned to normal. It will obviously need to be monitored on an on-going basis as it could change in the future, particularly during a future pregnancy. ...Read more
