A member asked:

Total t3 (liothyronine) level was 221...what does this mean?

A doctor has provided 1 answer

Probably not : Too much. It's slightly higher than normal, but the test is not a part of the routine thyroid evaluation and has very few indications. A freet4 and a TSH are much more helpful. Talk w/your doctor.

Does a very low level TSH hormone mean hypo - or hyperthyroidism? T3 (liothyronine) is normal range, T4 is at the low level borderline.

A member asked:

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?
