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
My TSH 3rd generation level came back at 9.490. MY T4 was normal and T3 (liothyronine) was low. Taking 200 mcg. What do these numbers mean?
Still hypothyroid: Not sure how long u have been on thyroid replacement, but if been on 200mcg daily over 6-8 weeks, likely require increase dose. If u have just had u'r medication adjusted the. Repeat TSH usually done in 6 wks; the numbers show that u'r body is still in hypothyroid state and that u'r thyroid gland is making less and less hormone or the T4 is not being converted to T3, (liothyronine) so thyroid medicine needed ...Read more

What does a normal TSH but low free T4 level mean? Can you have an underactive thyroid with a low T4 alone? Tsh 2.45 T4 7
Does a very low level TSH hormone mean hypo - or hyperthyroidism? T3 (liothyronine) is normal range, T4 is at the low level borderline.
Low TSH: Generally indicates an excess in thyroid hormone. That may be chronic w/hyperthyroidism -- or temporary w/thyroid inflammation. See you doctor. If you're already on thyroid replacement, the dose is too high. If you're on t3, (liothyronine) get off of it as it can be dangerous and doesn't work well as chronic replacement. Use brand name T4 only. ...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. 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

The T3 (liothyronine) you're receiving is potentially dangerous and should not be taken. It can not me measured in the blood and has potential toxicity. Use brand name T4 only if replacement is required, . ...Read more
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. This is a reflection of the pituitary being extremely sensitive to change in the T3 (liothyronine) level if you have symptoms it would be wise to seek treatment. ...Read more
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. The t4/t3 levels are measures of circulating hormone, so high T4 or T3 (liothyronine) suggest hyperthyroidism and vice versa. T4 levels can beaffected by hormones and so need to be interpreted carefully. For initial testing, the TSH alone best test. ...Read more
My ths levels are low (0.05) and my T3 (liothyronine) is 6.5 all so my T4 is 20.2, what medicine do I need to take?
Thyroid labs: Hi. See an endocrinologist. Make sure it's a free T4 (not a TOTAL T4). If you have low TSH and a low free T4, that's compatible with pituitary disease causing hypothyroidism (so called "secondary hypothyroidism"). IF you have that (not saying you do), you need to be checked for pituitary problems and other pituitary deficiencies (adrenal, most promptly); If u have secondary hypothy, CHECK ADRENALS ...Read more

I had bloodwork done for my thyroid and was told my T4's were extremely low. What does that mean?

Will ultimately need thyroxine replacement therapy. Symptoms of fatigue, constipation, dry skin, weight gain and hair loss will continue without thyroxine replacement. ...Read more
Does taking T4 only for a long period of time cause ones cortisol and iron levels to become low? Should 1 correct these b4 starting ndt
Not likely: Thyroid hormone does not cause iron to go down. However people with a well proven low cortisol (adrenal insufficiency) should correct their adrenal insufficiency before taking thyroxine (t4) as thyroid hormone can increase metabolism of cortisol. This does not apply to people with normal cortisol production, who can compensate very well for this effect. ...Read more
