As was pointed out earlier, PCM is especially suited to the purpose of rapid screening. If the physician is familiar with examining urinary sediments, using normal light microscopy, he is already able to distinguish red and white blood cells and bacteria. Very often he will see epithelial cells as well, but due to the lack of contrast, the details of these cells are never very clear. With PCM these contrasts are enhanced and by applying simple criteria normal and atypical cells can be distinguished (Figs. 8 and 9).
