What are normal aldosterone and renin levels?

On average for adults, the range of the Plasma Renin Activity runs between 0.7 and 3.3 ng/mL/hr (or 0.7 and 3.3 mcg/L/hr in SI units), and the range of the Plasma Aldosterone Concentration (PAC) goes from 7 to 30 ng/dL (or 190 to 830 pmol/L in SI units).

What is aldosterone direct renin ratio?

The aldosterone-to-renin ratio (ARR)—that is, the ratio of plasma aldosterone (expressed in ng/dL) to plasma renin activity (PRA, expressed in ng/mL/h)—is the most sensitive means of differentiating primary from secondary causes of hyperaldosteronism. It can be obtained under random conditions of sodium intake.

How do you calculate renin to aldosterone ratio?

Aldosterone-to-renin ratio can be given in ng/dL per ng/(mL·h), that is, nanogram per deciliter of aldosterone per nanogram per (milliliter x hour) of renin. Also, it can be given in pmol/L per µg/(L·h), where aldosterone is given in molar concentration. The former can be converted to the latter by multiplying by 27.6.

What does high aldosterone and normal renin mean?

High or low levels may help explain why you have high blood pressure: High renin with normal aldosterone may show that you’re sensitive to salt. Low renin and high aldosterone may mean your adrenal glands aren’t working the way they should. If both are high, it can be a sign that there’s a problem with your kidneys.

What are normal ranges for aldosterone?

The following are considered to be normal results for this test: Adults: Supine, normal-sodium diet: 2-9 ng/dL (55-250 pmol/L) [5] Upright, normal-sodium diet: 2 to 5 times supine value with normal-sodium diet [5]

What is high aldosterone level?

‌‌Too much aldosterone is called hyperaldosteronism. This extra aldosterone causes high blood pressure and low potassium levels. Sometimes it can look like moderate to severe high blood pressure and go undiagnosed for a long time.

What is an abnormal aldosterone level?

The high aldosterone level increases reabsorption of sodium (salt) and loss of potassium by the kidneys, often resulting in an electrolyte imbalance. Signs and symptoms include high blood pressure, headache, and muscle weakness, especially if potassium levels are very low.

How is hyperaldosteronism diagnosis?

How is hyperaldosteronism diagnosed? If your doctor thinks you might have hyperaldosteronism, he or she will order a blood test to check the levels of aldosterone and renin (a protein that is secreted by the kidneys and helps keep blood pressure levels in the normal range).

When should renin aldosterone ratio be checked?

A blood aldosterone test and a renin test are usually ordered together when someone has high blood pressure, especially if the person also has low potassium. Even if potassium is normal, testing may be done if typical medications do not control the high blood pressure or if hypertension develops at an early age.

What is a normal renin level?

Normal Results For normal sodium diet, normal value range is 0.6 to 4.3 ng/mL/hour (0.6 to 4.3 µg/L/hour). For low sodium diet, normal value range is 2.9 to 24 ng/mL/hour (2.9 to 24 µg/L/hour). Normal value ranges may vary slightly among different laboratories.
