A member asked:
Could this indicate hyperthyroidism? free t4 is 20 pmo/l, tsh is 2.2 miu/l, free t3 (liothyronine) is 6 pmo/l. upper ref. ranges for these are: 19, 4.9 and 6.

Not hyperthyroidism: Hi. The classic picture of hyperthyroidism is suppressed (usually undetectable) TSH and elevated free T4 and T3 (liothyronine). The "normal range" is determined as the 95% confidence interval where normal values lie, and by definition, excludes 5% of normal values. Your only value in the "hyper" range is the free T4, but it's just outside normal, and could easily be one of the 5% of normals outside the norm rang
