What levels indicate Hashimoto's?

The most common laboratory findings demonstrate an elevated thyroid-stimulating hormone (TSH) and low levels of free thyroxine (fT4), coupled with increased antithyroid peroxidase (TPO) antibodies.


Can you test negative for Hashimoto's and still have it?

Yes, negative antibodies doesn't necessarily mean you don't have the autoimmune condition Hashimoto's and because we know that it is responsible for 90% of us with hypothyroidism, that leaves up to 10% of those with hypothyroidism, having Hashimoto's but coming back negative on antibody tests.

Do TSH levels fluctuate with Hashimoto's?

A hypothyroid Hashimoto's patient may have a partly damaged thyroid gland that still secretes some thyroid hormones. During thyroid therapy, their TSH, FT4 and FT3 levels fluctuate unreasonably over time due to undiagnosed TSAb and/or TBAb antibodies.

Which is a marker is most reliable in diagnosing Hashimoto's thyroiditis?

The best marker of progression to overt hypothyroidism is a combination of an elevated TSH level with the presence of thyroid autoantibodies, namely anti-TPO and anti-Tg antibodies. The rate of progression to overt hypothyroidism is estimated to be about 5% per year.
