Atypical cells parameter in an automated urine analyzer: Does it have a future?

Sysmex UN-Series automated urine analyzer has recently introduced "atypical cells" parameter. These cells are supposed to be epithelial cells with features of suspicion for a neoplastic proliferation. Atypical cells parameter in urinalysis should be considered to be as useful as the blast parameter in hematology. However, it has many disadvantages compared to its counterpart. I suggest it should be used as a caution flag rather than a quantitative value to appear in the patient result page. A decision limit must be defined; perhaps the color parameter should be matched to define patients with both hematuria and atypical cells.
