About this test
Aldosterone controls how much salt the kidney holds on to, and an adrenal gland producing too much of it is one of the few genuinely curable causes of hypertension. It is measured with renin, because it is the ratio between the two rather than either number alone that points to the diagnosis.
What it measures
- Serum aldosterone
- Reported with renin for the aldosterone-renin ratio
A note on results. A single test is one part of a clinical picture, not a diagnosis. Discuss your report with a qualified doctor, who will read it alongside your history and examination.
