Hi Wendy
A raised WCC in urine might indicate Pm urinary tract infection.
A raised peripheral blood WCC in the setting of RA?
That's where the doctor shrugs his shoulders and doesn't answer the question.
Who knows? A component of high WCC could be due to an infection on top of the RA??
A good doctor never answers the question directly!
