The renin-angiotensin-aldosterone system (RAAS) is composed of three major compounds: renin, angiotensin 2 and aldosterone. When infants lack an enzyme needed to make cortisol, a condition called congenital adrenal hyperplasia, this can decrease production of aldosterone in some cases. Normal individuals will show a suppression of urinary aldosterone with adequate sodium repletion. In those who have primary aldosteronism, aldosterone is high while renin is low renin is said to be "suppressed." The higher the ARR result, the more likely a person has primary aldosteronism.
