Why it's done

By Mayo Clinic staff

The kidneys contain tiny blood vessel clusters that filter waste from your blood. Diabetes and high blood pressure can damage this delicate filtering system. Microalbumin tests can detect this damage at the earliest possible stages. Prompt treatment can help prevent kidney failure.

How often you need microalbumin tests depends on any underlying conditions and your risk of kidney damage. For example:

  • Type 1 diabetes. If you have type 1 diabetes, your doctor may recommend a microalbumin test once a year beginning five years after your diagnosis.
  • Type 2 diabetes. If you have type 2 diabetes, your doctor may recommend a microalbumin test once a year beginning immediately after your diagnosis.
  • High blood pressure. If you have high blood pressure, your doctor may recommend regular microalbumin tests. The optimal screening schedule varies, so ask your doctor what's best for you.

If your microalbumin level is elevated, your doctor may recommend more frequent testing. Remember, the earlier kidney problems are detected, the sooner you can begin treatment. If your kidneys fail, you'll need a kidney transplant or dialysis.
