I had a thyroid test which showed an abnormal level of free T4.
The TSH was normal: 2.73, ref range: 0.42-5.47 uIU/ml
Free T4 was high: 2.63, ref range: 0.59-1.17 ng/dl
An article on a physician's web page said that a high free t4 with a normal TSH rules out both hypothyroidism and hyperthyroidism. Does the high level of free t4 on my test indicate anything? I have no history of thyroid problems nor many symptoms of hyper or hypothyroidism. Is this test result something to cause concern and of what?
