A member asked:
If my tsh & t4 is within normal range but t3 is high and so is free t4 index. does this mean hyperthyroidism?

There is a condition called T3 thyrotoxicosis (hyperthyroidism with elevated T3) but TSH will be suppressed (low TSH level). If T4 and TSH are normal, you do not have hyperthyroidism (T3 is converted to T4 so T4 is more important).

All laboratory results need to be interpreted in the clinical context and the doctor who ordered the tests is usually in the best position to do that. Talk to the doctor who ordered the tests. Having said that, it would have helped had you provided the actual results. However with a normal TSH you are unlikely to have hyperthyroidism. Wish you good health!
