Figure 3. Effect of background cells on standard and microfilter-based urine cytology evaluation.

Figure 3

Based on the effects of confounding normal blood cells on cytology evaluation, samples assessed by each methodology were categorized into four groups. The percentages of samples in each group are plotted along the horizontal axis, and numbers of samples within individual groups are noted in their respective bars. Significantly higher proportion of samples processed by standard cytology had background cells that moderately or severely limited evaluation than microfilter-based cytology (p < 0.001).
