Primary hyperaldosteronism (Conn's syndrome) is characterized by-
high aldosterone and low renin because as there is hypo secretion of renin that fails to increase appropriately during volume depletion and hyper secretion of aldosterone that does not suppress in response to volume expansion (Harrison 17 pg 2260)
High renin, high aldosteorone
Low renin, high aldosterone
