what does microalbumin [mass/volume] in urine mean
A random microalbumin test measures the amount of albumin in a single sample of urine. The urine sample can also be tested for creatinine. A total microalbumin test measures the total amount of albumin in all of the urine your body makes in 24 hours. For a total microalbumin test, you need to collect and save all of the urine you make in 24 hours.
