Captopril suppression test

Aldosterone (chemical structure) is measured in the CST.

The captopril suppression test (CST) is a non-invasive medical test that measures plasma levels of aldosterone.[1] Aldosterone production is suppressed by captopril through the renin–angiotensin–aldosterone system. CST results are used to assist in the diagnososis of primary aldosteronism (Conn Syndrome).
