What you can expect
By Mayo Clinic staffDuring the microalbumin test, you simply need to provide a fresh urine sample. This may be done in several ways:
- 24-hour urine test. Your doctor may ask you to collect all of your urine in a special container over a 24-hour period and submit it for analysis. The 24-hour urine test provides the most accurate microalbumin results.
- Timed urine test. Your doctor may ask you to provide a urine sample first thing in the morning or after a four-hour period of not urinating.
- Random urine test. A urine sample provided at a random time is usually adequate if both microalbumin and creatinine — another waste product usually filtered by the kidneys — are measured.
The urine sample is sent to a lab for analysis. After you provide the urine sample, you can return to your usual activities immediately.
