Well, an ENT infection cannot increase the
urine WBC. It can result in high WBC in
blood though. I am not sure why the
urine test was done. You had some symptoms? A high WBC in urine and no culture can happen if the UTI is caused by an organism that does not show growth on normal cultures. Certain special cultures are set up for them. Your urologist can help you with this.
In case you have no symptoms, then there is a possibility of error in the report. Maybe you should get a repeat test done.
