[Is the aldosterone-renin ratio useful in screening for primary aldosteronism?].

Despite improving laboratory and imaging methods the diagnosis of primary aldosteronism still remains a problem. One of the reasons is inadequate sensitivity of classical screening of this secondary arterial hypertension by hypokalemia. In the submitted paper the authors review data from the literature on more sensitive screening by means of the aldosterone-renin ratio. Its inclusion among basic examinations in patients with arterial hypertension seems fully justified.
