What causes high WBC in urine of a child?
Patient: My seven year old daughter had a urinalysis done due to a possible UTI. There was no growth, but a high white blood cell count. Her father has psoriasis, and thinks that could be what is causing this. She has no symptoms of that, so what could the high white blood cell count be from? Doctor: Hello,  Sometimes white blood cells in a child's urine are normal. It depends on the count. The fact that there was no growth in the urine sample means there was no bacterial infection. White blood cells are also released when there is inflammation - serious or not. It would unusual that this would indicate Psoriasis. I would retest her urine a few times and see if it resolves or is of a minimal level. Mostly, without other symptoms, I don't want you to worry. Hope I have answered your question. Let me know if I can assist you further.  Regards, Dr. Lisa Baker, Pediatrician
