A free T4 level in the optimal range usually indicates normal thyroid gland function. A free T4 level in the normal range is usually accompanied by a TSH level that is also in the normal range. When combined with an elevated TSH level, a normal free T4 may indicate subclinical hypothyroidism. When combined with a low TSH level, a normal free T4
