Do I have PA?
If you suspect that you have primary aldosteronism — and especially if you fall into one of the high risk categories listed on this website — you should ask your Primary Care Physician to order a blood test for aldosterone and renin. If your physician is not familiar with these tests or with primary aldosteronism, you should ask for a referral to an endocrinologist. These blood tests will allow your physician to calculate your aldosterone-to-renin ratio (ARR). A high ARR test result makes it likely that you have primary aldosteronism. In most cases, you will also need to get a separate confirmatory test.
