Risk factors: You have a few risk factors for being of slight build such as prematurity and chronic inhaled steroid use. The thyroid levels you have reported reveal a TSH within normal range and T4 (free?) slightly below normal, however, the units your labs reported in may vary from the references I am using. Abnormal thyroid levels should be repeated in 3-6 months to detect trends.
