Could a low TSH (.28) & normal T3 (liothyronine) & T4 levels mean a Pituitary issue? Or is that more typical of hypothyroidism? Would high Chloride (111) effect it?

Could a low TSH (.28) & normal T3 (liothyronine) & T4 levels mean a Pituitary issue? Or is that more typical of hypothyroidism? Would high Chloride (111) effect it?

Means pituitary is: A TSH of 0.28 with normal free T4 and free T3 (liothyronine) likely means the pituitary is working properly. A TSH of 0.1-0.4 is lower than the reference range, which means about 2.5% of normal people have a TSH or 0.1-0.4. Thus, one hopes she is normal. Her endocrinologist can follow and recheck her levels in 4-6 weeks to confirm that her levels are stable (TSH not dropping lower; T4 or T3 (liothyronine) not above normal). ...Read more

Due to thyca can you have low TSH and high tg? Or if tg increases does the tsh?

Low TSH unlikely: Thyroid cancer usually does not cause a low TSH (unless you are taking thyroid hormone). Most thyroid cancers do not function as well as normal thyroid tissue.

High tg has nothing to do with tsh. ...Read more
