Normal Values:

Normal values range from 1.5 to 85 micrograms per 24 hours. However, results depend on the amount of sodium in your diet. The greater the amount of dietary sodium, the lower the level of aldosterone.

Results may be questionable if your kidneys do not function properly.

Normal value ranges may vary slightly among different laboratories. Talk to your doctor about the meaning of your specific test results.

What abnormal results mean:

Greater than normal levels of aldosterone may be due to:

• Conn's syndrome
• Bilateral adrenal hyperplasia
• Abuse of diuretics ("water pills")
• Laxative abuse
• Cirrhosis
• Heart failure

Lower than normal levels may indicate Addison's disease.
