The decreased TSH level seen in SCH results from the pituitary's response to minor elevations in serum or tissue T4 and T3 levels.1 Although these levels remain within the normal range, the increases are sufficient to decrease the serum TSH level. The prevalence of SCH depends on the level ...
But T3 uptake % is not very useful by itself. The T3 uptake test must be performed alongside a total T4 test in order to calculate free T4, also called the free T4 index. A high free T4 index may indicate hyperthyroidism while low levels may point to hypothyroidism [2]. ...

Res-O-Mat T3 values distributed within normal levels in 1st trimester and mole and higher in 3rd. trimester. Free T4 indices were almost normal during pregnancy and 2.4 times higher in mole. Free T4 levels, measured with dialysis and RIA, were slightly low during pregnancy but remarkably high...
Normal serum free thyroid hormone concentrations in patients treated with phenytoin or carbamazepine. A paradox resolved. OBJECTIVE: To address the paradox that phenytoin- and carbamazepine-treated patients have decreased serum free thyroxine (T4) and triiodothyronine (T3) con... MI Surks,CR Defesi ...
Free T4 and free T3 levels declined during pregnancy (13.7 +/- 2.0, 13.5 +/- 4.1, 11.2 +/- 2.8, 10.2 +/- 1.6 pmol/l, P = 0.005; 4.55 +/- 0.63, 4.64 +/- 0.88, 3.72 +/- 0.67 and 4.01 +/- 0.75 pmol/l, P = 0.003), whereas free reverse T3 levels increased during ...
The disparity between FT4I and FT3I ranges was also reflected in the true free T4 and free T3 levels which were measured in some cases. These results suggest that when an increased FT4I is found in an elderly woman with cardiac disease, caution should be exercised in interpreting the result...
