Testing for microalbumin, is on of the dip tests they do on your urine sample when you go to clinic, sometimes they may ask you to do a 24 hour collection of your urine to test further at the lab but this is dependant if they find any or how much they find..
Now hospital clinics, actually use a machine to read the dip test strips rather than the old fashioned match the colour by eye method!! Which of cause gives more accurate information and results
I know that at my doctor surgury, they've just implemented a yearly request of all there diabetics, even though I have one every time I go to the hospital clinic!
