Hypothyroid and T3: If the TSH is normal, then that is strong evidence that you are normal. Pituitary TSH responds mostly to T3. If you T3 were too low, the TSH should be high. Indeed, I am not sure why T3 is being measured. There are more problems with the T3 assay than that of T4. This could just be "lab error". ...Read more

Normal range but,,,: The TSH and T4 and t3 (liothyronine) are in normal range but TSH is low normal and T4 is fairly high normal depending on the reference ranges. A free T4 would help also.

HiTSH=hypo,hiT4 hype: Thyroid function is measured many ways. The TSH is your body's call for more hormone, so a high TSH suggests underactive thyroid, very low TSH overactive.

Yes: Your results are normal.

Higher dose: Tsh is more sensitive than T3 (liothyronine) or T4 levels for identifying patients whose thyroid levels are abnormal for them. A high TSH means that your pituitary gland is trying to get your thyroid to make more thyroid hormone. Since your thyroid can't (or you wouldn't be on thyroid hormone), you probably need a stronger thyroid tablet. Talk to your doc to make sure you're getting the most from your pills. ...Read more

Slightly low: I see that you are on thyroid hormone. The TSH will be the best indicator of whether you need more or less medication. The ideal TSH is around 1-2, so currently you could use a slightly higher dose. The "normal range" applies to a population of people. Your individual normal range is much more narrow. If your pituitary wants your free T4 to be 1.3 or 1.4, it will put out TSH to try to do so. ...Read more

Subclinical hyperthy: The T3 (liothyronine) and T4 levels are normal, but the TSH is slightly low. You did not mention if you are any medication for your thyroid.

Most people with this mild an abnormality will have no symptoms. It should be followed. ...Read more

Hypothyroidism: This likely indicates secondary hypothyroidism, due to problem with your pituitary gland.

However, if there is a problem with the pituitary, then the TSH is either low or normal despite a low T4. Be sure to follow up with the doctor how ordered these tests. ...Read more

Depends: The T3 (liothyronine) may be low before you take your medication and isn't necessarily abnormal.
