What does it mean when the routine urine test shows negative for white blood cells?

A negative leukocyte result in routine urinalysis indicates that the number of white blood cells in the urine is within the normal range, with no significant elevation observed. This finding usually suggests the absence of bacterial infection in the urinary tract, meaning there is no urinary system infection such as urethritis or cystitis. A negative leukocyte result in routine urinalysis is considered normal and generally reflects good health of the urinary system. However, it is important to note that if a large amount of water was consumed before the test, the urine may be diluted, potentially leading to a false-negative result for white blood cells. Therefore, when interpreting routine urinalysis results, other test findings and the patient's specific symptoms should be taken into comprehensive consideration.
