What causes high white blood cells in urine test?

Causes of high white blood cells in urine:

1. Urinary tract infection (UTI): Urinary tract infections are the most common cause of elevated white blood cells in urine. When bacteria invade and multiply in the urinary tract, the body responds by increasing white blood cell count to fight the infection. This is often accompanied by symptoms such as frequent urination, urgency, and painful urination.

2. Kidney diseases: Certain kidney conditions, such as nephritis or kidney stones, may also lead to increased white blood cells in urine.

3. Other systemic diseases: Some systemic diseases, such as diabetes and rheumatic disorders, can also cause an increase in white blood cells in urine. These conditions affect the body's immune system, making it more likely for white blood cells to be released into the urine.
