RTE cells are indicated by the arrows in the top image. WBCs are indicated by the arrows in the bottom image.
- Observe size: An RTE cell is larger than a WBC.
- Observe the nucleus:. The RTE cell will have a single round nucleus, which is located eccentrically in the cell. A WBC in urine is usually a segmented neutrophil, which has 3-5 lobes.
- Use a supravital stain or Papanicolaou stain to enhance cellular elements.
