A relatively high white blood cell count on a urine test is usually suggestive of a urinary tract infection. A normal person’s urine contains a small amount of white blood cells. If the white blood cell count in centrifugal urine exceeds 10 cells/HP or if the white blood cell count in a normal urine test exceeds 5 cells/HP, it should be considered a urinary tract infection. Depending on the difference in white blood cell count, urinary tract infections can be classified as mild or severe urinary tract infections. When urinary tract infection is present, it is often accompanied by symptoms of frequent urination, urgent urination and painful urination. The causes of urinary tract infections are more divided into two main categories, the first being non-specific infections and the second being specific infections. Non-specific infections are generally more common with Escherichia coli. Specific infections are relatively rare and are mainly caused by Mycobacterium tuberculosis and Neisseria gonorrhoeae. For urinary tract infections, the treatment is mainly anti-infection therapy, which can be combined with urine culture and drug sensitivity tests for optimal drug selection and treatment.
