What Does A Low T4 Level Mean
What does it mean if T4 (7.23) level is norm but ft4 (2.15) is elevated in graves disease while on mmi. If dose is increased, will T4 drop too low?
Graves medications: It can be tricky to adjust the dose of Methimazole in someone with graves disease. Too much Methimazole can make you hypothyroid. The ft4 is more reliable than the total t4. The TSH will probably stay suppressed unless your thyroid has been normal for a long time. Another factor is your symptoms. If you feel ok, the slightly elevated ft4 may be ok. ...Read more

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.

Hypothyroidism: The TSH test is10 times more sensitive for the diagnosis of hypothyroidism that the t4. The TSH is reported on a log scale so that small changes in the TSH value are caused by relatively big changes in the blood level.
