Can a drug test come out positive if I'm taking quinapril?

Well, If your asking if the drug can be tested for, the answer is yes, but this is not an illegal drug--it is a drug for blood pressure and heart failure. So it would not make a drug screen for illegal drugs positive. It is a prodrug that is metabolized to its active form by the liver; an ACE inhibitor. BUT, if you are a person who is not supposed to be on any kind of drugs, a test can show it.
