What is a renin test?

ANSWER

Your doctor may order this kind of test if high blood pressure starts when you’re young or medication doesn’t keep it under control. Renin is an enzyme that helps control your blood pressure. When your blood pressure drops too low or your body doesn’t have enough salt, renin gets sent into your bloodstream. That triggers a chain reaction that creates a hormone called angiotensin and signals your adrenal glands to release another hormone called aldosterone.

Angiotensin makes tiny blood vessels narrower, and aldosterone tells your kidneys to hold on to salt and fluid. Both those things can raise your blood pressure. If that process gets out of balance, your blood pressure can get too high.
