Order Aldosterone-to-Renin Ratio Test | Lab TestThe aldosterone-to-renin ratio is a laboratory calculation that compares the concentration of aldosterone in the blood with that of renin. Because the two hormones interact as part of a feedback loop that regulates sodium balance and blood pressure, their relationship can be more informative than either value alone. The ratio is most often used to screen for primary aldosteronism, a condition in which the adrenal glands produce too much aldosterone while renin remains suppressed.
About Aldosterone-to-Renin Ratio Test | Lab Test in Clearfield
The aldosterone-to-renin ratio is a screening tool, not a standalone diagnosis.
Aldosterone is a steroid hormone produced by the adrenal glands. It prompts the kidneys to retain sodium and excrete potassium, which helps maintain blood volume and pressure. Renin is an enzyme released by the kidneys when blood pressure or sodium delivery to the kidney falls. Renin triggers a cascade that ultimately raises aldosterone production, so the two hormones normally rise and fall together.
In primary aldosteronism, aldosterone production becomes excessive and partly independent of renin. The kidneys sense the resulting sodium retention and volume expansion, and they reduce renin release in response. A high aldosterone level paired with a low renin level produces a ratio that is elevated, which is why the ratio is used as an initial screen.
Several factors can influence the result, including potassium levels, certain medications, and the time of day the sample is collected. Because of this, the test is typically interpreted alongside other laboratory findings and clinical information. An elevated ratio generally prompts confirmatory testing before any diagnosis is made, and a normal ratio does not by itself exclude every form of hypertension.
