Thyroid: The usual tests done for thyroid are TSH ( thyroid stimulating hormone) and T4 -thyroid hormone, T3 is the active form but is checked less frequently. . If the 0.914 is T4 it is low ( labs differ on the range) but you need TSH as well , if TSH is high you likely would need thyroid hormone replacement which many people are on. f/u /w/ endocrinologist
