Epithelial cells in urine are important biomarkers that provide insights into kidney and urinary tract health. Understanding their levels helps diagnose infections, inflammation, and other health conditions.
Epithelial cells are found on the surface of organs, skin, and various body structures, including the urinary tract. When these cells appear in urine, they can come from the kidneys, bladder, or other parts of the urinary system.
These cells are usually shed naturally. Having a small amount of epithelial cells in urine is normal. However, a high level may indicate underlying health issues.
In medicine, epithelial cells in urine serve as a biomarker. They help healthcare professionals detect various conditions. By examining these cells, doctors can gather information about infections, inflammation, or diseases affecting the kidneys or urinary tract.
The presence and type of epithelial cells—squamous, transitional, or renal—can help identify which area of the urinary tract may be affected. This information aids in accurate diagnosis and timely treatment.
