Yes: TPO antibodies indicate that your immune system is producing AB against your Thyroid. Look up Leaky Gut and address it by diet, (no gluten or dairy) supplementation, and life style changes. Once resolved you AB will get to normal levels. ...Read more

Thyroid peroxidase: An elevated anti-TPO antibodies could indicate Hashimoto's thyroiditis. However, it is not clear that yours are actually elevated. If the TSH is normal, it is unlikely that this is affecting you; maybe these are perimenopausal sx. Even if the anti-TPO were elevated, that would indicate an autoimmune process is underway, but it may take years for it to cause actual hypothyroidism. ...Read more

Lab results as follows: ANA w/titre and pattern 1:320 and thyroid peroxidase ab 484.0....Are the two related? Would hashimoto's cause high ANA level?

Lab results as follows: ANA w/titre and pattern 1:320  and thyroid peroxidase ab 484.0....Are the two related? Would hashimoto's cause high ANA level?

No: You have an elevated thyroid peroxidase (tpo) antibody because you have a tendency towards autoimmunity. The elevated tpo causes hoshimoto's. The tendency towards autoimmunity causes the high ANA level. ...Read more

Post op thyroid: Surgery for cancer the replacement thyroxine should be dosed sufficient to keep TSH low to avoid stimulating any tumor remnants. Most Endocrinologists advise suppressing tsh for about 5 years. Thyroglobulin levels and antibodies should also be measured. Your TSH level appears adequately suppressed.

Thyroid peroxidase ab results 96 all other levels normal do I have hypothyroidism?

Thyroid peroxidase ab results 96 all other levels normal  do I have hypothyroidism?

No: Tpo ab's do not diagnose hypothyroidism. Only thyroid function tests (free t4, tsh) can do that. If you don't have hypothyroidism, why are you on levothyroxine? If you do have hypothyroidism and need t4, make sure it's brand name medication as the generics are unreliable. ...Read more

Thyroid antibodies: The presence of anti-thyroid peroxidase antibodies signals the presences of autoimmune thyroid disease. This is often, but not always, associated with underactivity of the thyroid. The change in level of the antibodies does not have any real significance; what is important is that your dose of thyroid hormone replacement results in your having a normal TSH level. ...Read more
