The following is the normal reference range for urine white blood cells:
| Check items | normal value range | Exception prompt |
|---|---|---|
| Urine white blood cells (microscopic examination) | 0-5/high power field (HPF) | >5/HPF may indicate infection |
| urinary leukocyte esterase | negative | Positive may indicate bacterial infection |
2. Common causes of elevated urinary white blood cells
According to recent discussions in medical forums and health self-media, the main causes of elevated urinary white blood cells include:
| Cause classification | specific disease | Proportion (reference) |
|---|---|---|
| Infectious diseases | Cystitis, urethritis, pyelonephritis | about 65% |
