Results
By Mayo Clinic staffResults of the microalbumin test are measured as milligrams (mg) of protein leakage over 24 hours. 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)
Discuss your test result with your doctor and what it means for your health. If your urinary microalbumin level is higher than normal, your doctor may recommend repeating the test.
Several factors can cause higher than expected urinary microalbumin results, such as:
- Blood in your urine (hematuria)
- Certain medications
- Fever
- Recent vigorous exercise
- Urinary tract infection
- Other kidney diseases
