However, a sizable proportion of these laboratory abnormalities do not warrant therapy or endocrine follow-up. The objectives of this study were (a) to evaluate the prevalence of true thyroid dysfunction among pediatric endocrinology referrals for abnormal TFTs; (b) t...

It is excusable for doctors to believe that if the serum thyroxine concentration is higher than the so-called normal range that the dose of thyroxine sh...
