The medical term for white blood cells in urine is "leukocytes." The presence of leukocytes in urine commonly indicates that the body is fighting an infection. Typically, elevated leukocyte levels in urine suggest the possibility of a urinary tract infection (UTI), but can also be indicative of kidney issues or other infections within the urinary system.

Several sources provide insights into leukocytes in urine. According to WebMD, the detection of leukocytes can serve as a sign of infection, and understanding the underlying causes is crucial for appropriate treatment. Healthline further clarifies that high leukocyte levels often correlate with a urinary tract infection, prompting medical evaluation for symptoms and treatment options.

Medical News Today reinforces this point, noting that elevated leukocyte levels are linked to infections in the urinary system. Additionally, the Mount Sinai article focuses on a specific screening test known as the leukocyte esterase urine test, which detects byproducts of white blood cells, thus indicating their presence in the urine.

Further information is provided by Care Hospitals, which explains that the appearance of leukocytes in urine, especially in high amounts, necessitates examination as it frequently signifies an infection. Tua Saúde mentions that while low levels of leukocytes could be normal, high levels warrant further investigation due to the associated risk of UTIs and other conditions.

Lastly, Sysmex highlights "pyuria," the term used specifically for the presence of white blood cells in urine, elaborating that it points to potential bacterial infections, among other health concerns.
