What Does A High Thyroxine Mean
T3 uptake and T4 thyroxine and free T4 index are normal, but TSH is4.65 and per the lab that is high. The highest normal is 4.5. What does this mean?
Once - Nothing!: Any symptoms? Sublinical hypothyroid or nothing. This is an odd combo of tests as T4 & FTI essential measure the same thing. Your TSH is just above normal & there is sometimes variability in the test. I would suggest, repeat testing by an endocrinologist about 2 weeks after this one, with antithyroid antibodies. If (+) closer monitoring, if (-) less close f/u. Fam Hx also important. Don't worry! ...Read moreSee 1 more doctor answer

Elevated TSH with nl: When ft4 is normal and TSH elevation may indicate subclinical hypothyroidism or acute illness like surgery and pregnancy or any condition that increases thyroid binding hormones.

I am currently on a high dose of thyroxine (250mcg). I do not have any symptoms of hyperthyroidism. Should i be concerned by this high dose?
Depends on your TSH: Some patients require higher doses of medications. Your physician should monitoring your thyroid function via blood tests (tsh). Typically, a TSH is checked 6-8 weeks after starting a new dose and at least once a year once your dose is stable. If you have a lot of weight loss or gain you may need rechecked as well. If your TSH is in a good range then you need that high of a dose. ...Read moreSee 1 more doctor answer
My tsh, ft3 & ft4 levels have increased significantly over the past 6 weeks, following a 50mcg increase in my thyroxine dose. What does this mean?
Recheck the labs: Based on your question, this does not make sense. An increase in your thyroid dose should increase the T3 and t4, and decrease the tsh. Was there a lab error? Are you taking the meds correctly? Is there something else going on with your thyroid? Are you in recovery from a severe illness? Check with your doctor. ...Read more

Maybe hyperthyroid?: Some people who are taking levothyroxine for hypothyroidism may at times experience swings towards the opposite (hyperthyroidism). Some of these swings are transient, others last longer (graves' disease). A good endocrinologist should be able to sort things out in these situations, with a number of tests, such as graves' disease antibody and/or radio iodine thyroid scan. ...Read more
