What does an aldosterone test show?

What is an aldosterone (ALD) test? This test measures the amount of aldosterone (ALD) in your blood or urine. ALD is a hormone made by your adrenal glands, two small glands located above the kidneys. ALD helps control blood pressure and maintain healthy levels of sodium and potassium.

How do you test for aldosterone levels?

What is normal range for aldosterone test?

Reference ranges: Plasma aldosterone, supine position and normal sodium diet: 2-9 ng/dl (55 – 250 pmol/L) Plasma aldosterone, upright position (standing / seated for at least 2 hr) and normal sodium diet: 2 – 5x supine value. Urine aldosterone: 5 – 20 μmg/24 hr (14 – 56 nmol/24 hr)

What is the rule of aldosterone?

Aldosterone is a steroid hormone secreted by adrenal glands. Its main role is to regulate salt and water in the body, thus having an effect on blood pressure.

What happens if aldosterone is high?

Hyperaldosteronism is a condition in which one or both adrenal glands produce too much of the hormone aldosterone. This can lower potassium levels, which can cause weakness and muscle spasms. Hyperaldosteronism can be treated with medication, or if necessary, surgery.

How long do aldosterone tests take?

Check with physician before stopping any medications. Test Results: 4-7 days. May take longer based on weather, holiday or lab delays.

What is ARR test?

The aldosterone-renin activity ratio blood test is used to detect excess or deficiency in aldosterone and renin levels and to help diagnose primary aldosteronism (PA, also known as Conn syndrome). This test looks at the ratio between these two hormones to help make that diagnosis.

How is hyperaldosteronism diagnosed?

Primary hyperaldosteronism is diagnosed by measuring the blood levels of aldosterone and renin (a hormone made by the kidney). To best measure these hormones, blood samples should be drawn in the morning. In primary hyperaldosteronism, the aldosterone level will be high while renin will be low or undetectable.

What happens if aldosterone is low?

Low aldosterone (hypoaldosteronism) usually occurs as part of adrenal insufficiency. It causes dehydration, low blood pressure, a low blood sodium level, and a high potassium level.

What happens when aldosterone levels are high?

How is aldosterone activated?

The release of aldosterone from the adrenal glands is regulated via the renin-angiotensin II-aldosterone system. This system is initially activated via a decrease in the mean arterial blood pressure to increase the blood pressure.

What is the treatment for high aldosterone?

How is hyperaldosteronism treated? The treatment of hyperaldosteronism depends on the cause. If the cause is hyperplasia in both adrenal glands, your doctor may prescribe a drug that blocks the effects of aldosterone. These drugs include spironolactone (Aldactone®), eplerenone (Inspra®), or amiloride (Midamor®).

What is the aldosterone test?

When you get this test, a lab tech takes a small sample of your blood to measure how much of the hormone aldosterone is in your system. That result will help your doctor figure out what’s going on with your blood pressure.

How do you know if you have secondary aldosteronism?

If your results show a high level of aldosterone and a high level of renin, you may have secondary aldosteronism. If your aldosterone and cortisol levels are lower than normal, and your renin level is high, you may be diagnosed with Addison’s disease.

What does aldosterone do for the body?

Aldosterone balances the levels of sodium and potassium in your body. It signals to your organs, like your colon and kidneys, to put more sodium into your bloodstream or release more potassium into your pee.

What does it mean when your aldosterone and cortisol levels are low?

If your aldosterone and cortisol levels are lower than normal, and your renin level is high, you may be diagnosed with Addison’s disease. If your aldosterone and renin levels are low, while your cortisol level is high, you may be diagnosed with Cushing syndrome. University of California San Francisco Medical Center: “Aldosterone.”
