Urinalysis (cont.)

Cells Detected by Urinalysis

Some of the cells detected in a urinalysis are epithelial cells, red blood cells, and white blood cells. Epithelial cells are the cells lining many structures in the body, such as the urethra, bladder, ureters, vagina, or skin. The presence of epithelial cells in the urine may represent contamination of the sample; however, these cells in urine may also be associated with an inflammation or infection of the urethra or bladder.

With microscopic analysis, the quantity of cells in the urine can be estimated, and the number of cells (white blood cells, red blood cells, epithelial cells, and bacteria) in the urine is reported as the number of cells seen in one high power field (number of cells viewed in one field under the highest magnification of the microscope lens).
