Primary aldosteronism: A contrarian view.

This paper provides evidence that primary aldosteronism is likely much less common than is believed by the other authors of this collection. The basis for this contrarian view is simple: there is no way to know the true prevalence of PA because of the uncertain validity of all of the diagnostic procedures used to find and characterize this disease. Moreover, even if these uncertainties are overcome, the eventual treatment of most who have PA can be provided without the need for extensive testing and expensive treatment.
