What is a safe range for microalbumin in urine for a diabetic?

The safe range for microalbumin in urine for a diabetic person is below 30 mg per 24 hours. This may vary slightly among different laboratories that use different measurements or test different specimens, according to MedlinePlus.

Results of between 30 mg and 300 mg of microalbumin indicate early kidney disease, while results over 300 mg indicate advanced kidney disease, states Mayo Clinic. People with diabetes are at a higher risk of kidney disease and are therefore advised to have this test done at least once a year, explains MedlinePlus. Urine creatinine levels may also be measured along with the microalbumin test to make the results more accurate, states MedlinePlus.
