Is a female urine white blood cell count of 800/ul very serious?

Generally, whether a urine white blood cell count of 800/μL in women is serious depends on the specific underlying cause. If the elevated white blood cells are due to an infection, the condition is usually considered more serious. However, if the increase is caused by physiological factors, it is generally not severe. Individuals experiencing discomfort should seek medical attention promptly for professional evaluation and treatment under a doctor's guidance. Detailed analysis is as follows:

If the elevated urine white blood cell count of 800/μL in women is caused by an infection, it is typically considered serious. For example, urinary tract infections (UTIs), if left untreated, may lead to severe complications in pregnant women, including preterm labor and low birth weight.

In some non-pathological situations—such as recent sexual activity, intense physical exercise, or emotional stress—white blood cells in the urine may temporarily increase. In these cases, the elevation is usually short-lived, rarely accompanied by other symptoms, generally not serious, and may not require specific treatment.

Women who have a urine white blood cell count of 800/μL should promptly consult a healthcare provider for proper evaluation.
