This test is aslo known as Aldosterone Test, Renin Test, Aldosterone and Renin Ratio Test, Aldosterone and Renin Activity Test, PRA Test, Plasma Renin Activity Test.
Aldosterone is a hormone that plays an important role in maintaining normal sodium and potassium concentrations in blood and in controlling blood volume and pressure. Renin is an enzyme that controls aldosterone production. The Aldosterone/Plasma Renin Activity (PRA) Ratio test measure the levels or the ratio between aldosterone and renin in the blood.
Therefore this test is most useful in testing for one of the major causes of high blood pressure and can identify issues with the adrenal gland.
Input your data
When someone has high blood pressure, a blood aldosterone test and a renin test are generally requested together, especially if the person also has low potassium. Even if potassium levels are within normal limits, testing may be necessary if standard drugs fail to control high blood pressure or if hypertension develops at a young age. Because primary aldosteronism is a potentially curable form of hypertension, it’s critical to catch it early and effectively treat it.
When a healthcare practitioner suspects adrenal insufficiency or Addison disease, aldosterone levels, along with additional testing, are occasionally recommended. The aldosterone stimulation test, also known as ACTH stimulation, measures aldosterone and cortisol levels to identify whether a person has Addison disease, reduced pituitary function, or a pituitary tumor. After ACTH stimulation, a natural outcome is an increase in cortisol and an increase in aldosterone.
For a blood aldosterone and renin measurement, the health care practitioner may ask you to be upright or lying down for a period (e.g., 15 to 30 minutes) prior to sample collection. Before the test, you may also be instructed to avoid certain beverages, foods, or medications. However ask your doctor & follow accordingly.
