ALDO/PRA Ratio details
What ALDO/PRA Ratio shows
The ALDO/PRA ratio is calculated by dividing your blood aldosterone level by your plasma renin activity. Renin normally controls how much aldosterone your adrenal glands release, so the two usually move together. The ratio is used mainly to screen for primary aldosteronism, a condition in which the adrenal glands make too much aldosterone on their own, which can cause high blood pressure and sometimes low potassium. A high ratio suggests aldosterone is being made independently of renin, while a normal ratio makes this less likely. Many blood pressure medicines, salt intake, potassium levels, posture and time of day affect the result, so a high ratio needs confirmatory testing.
Tests that include ALDO/PRA Ratio
The Aldosterone-renin ratio is used to screen for primary aldosteronism.
- ALDO/PRA Ratio A ratio calculated from aldosterone and plasma renin activity, used mainly to screen for primary aldosteronism as a cause of high blood pressure.
- Aldosterone, LC/MS/MS Measures aldosterone, the adrenal hormone that controls salt, potassium and blood pressure, using a precise mass spectrometry method.
- Plasma Renin Activity, LC/MS/MS Measures plasma renin activity, an enzyme that controls blood pressure and salt balance, mainly used with aldosterone to look for causes of high blood pressure.
