The prevalence of elevated thyroid antibodies increased...

... reproducibility of the tests and by a regression to the mean effect. Moreover, it is possible that ‘normal values’ increase with age. Other determinants of normal peak values may also change from childhood to adulthood and contribute to ‘normalization’. The absence of a gold standard for the diagnosis...
