Endocrine / Hormones
Also known as: Renin blood test, PRA, Aldosterone and Plasma Renin Activity
No common urgent flag from this test alone
This test checks how much renin is working in your body. Renin is a special helper made by your kidneys. It helps keep your blood pressure steady. It also helps balance the salt and water in your body.
Your doctor orders this test to see if your adrenal glands are making too much or too little of a hormone called aldosterone. This test also helps check high blood pressure. This is especially true if your blood pressure is hard to control with regular medicines.
Reference ranges for Plasma Renin Activity can vary significantly between different laboratories. Interpretation also depends on factors like age, sex, pregnancy status, specimen type, clinical context, and the specific lab performing the test.
