I get the microalbumin test with a urine sample every three months. The new endo wants a 24-hour urine collection. I haven't done this for a long time. Do you guys do it, and how often? I'm not having any kidney problems. It's such a pain because you have to go get the special collection bottle, put all the urine in there, and keep it in a cooler while you're doing the collection. Any tips?
