Urine Epithelial Cells
Epithelial cells are surface-lining cells that naturally shed from the urinary tract and nearby areas into the urine. A urinalysis notes how many appear under the microscope.
A few epithelial cells are a normal part of everyday cell turnover. Their main practical value is helping judge whether a urine sample was cleanly collected, since many cells can suggest contamination from the skin or genital area. In some cases the type and number can offer additional clues your clinician interprets alongside the rest of the results.
Many epithelial cells often suggest the sample picked up cells from the skin or genital area, hinting at collection technique rather than disease. Certain types in higher numbers can occasionally reflect irritation or inflammation a clinician may consider.
A small number of epithelial cells is normal and generally reflects a clean sample and routine cell shedding.
A few epithelial cells per high-power field is typical and expected. A high count may prompt a repeat sample with careful collection, and your clinician interprets the finding in context.
