Do you need to fast for a microalbuminuria test?

No. Microalbuminuria is the presence of small amounts of protein in the urine, usually too small to note on a dipstick test. A trace amount of protein can be normal, but usually there is none. The most common cause of m is diabetes mellitus; it usually indicates that the dm has started to affect your kidneys. Once this happens, take things more seriously: talk with your pcp and consider endocrinology.
