Each practice microscopic first shows the urine chemistries. These can give an important hint as to what to expect in the microscopic. After that, there are a few images from low power to quantitate casts, if any. In my lab, this is the only element quantified on lower power. After that, everything else is quantified on high power from the given images. Assume each image is a new field. Select the correct range from the drop down, or leave as negative (=). Finally, compare with the given answer sheet to see if you match!
