Male, or female?
Actually, googling "microscopic hematuria" brings up an American Urological Assn guide, a Mayo Clinic guide, and a Cleveland Clinic guide. And also a Canadian algorithm. Looks like they are pretty similar except in the number of samples required, and that there are lots of false positives.
Interestingly, over here, the finding is usually reported as "rbc's per high power field", and can be on either an unspun or spun specimen.
