Results

By Mayo Clinic staff

Results of the microalbumin test are measured as milligrams (mg) of protein leakage. Generally:

  • Less than 30 mg is normal.
  • Thirty to 300 mg indicates early kidney disease (microalbuminuria).
  • More than 300 mg indicates more advanced kidney disease (macroalbuminuria).

Keep in mind that target microalbumin levels may change depending on many variables — including age, sex and testing method. It's also important to note that microalbumin levels can be affected by vigorous exercise, dehydration, blood in the urine, urinary tract infection and the use of certain drugs.

If your microalbumin level is higher than normal, your doctor may want to confirm the results with a 24-hour urine test.

If kidney damage is a concern, your doctor may adjust your diabetes or high blood pressure treatment plan. Often an angiotensin-converting enzyme (ACE) inhibitor or angiotensin II receptor blocker (ARB) is prescribed to decrease the amount of protein in the urine. You can't undo kidney damage, but with appropriate treatment you may be able to prevent further damage.
