If there a an elevated WBC in the UA, it could be a sign of a UTI; however, it is not always the case. There are other markers in the UA such as leuk esterase which is an enzyme that bacteria uses for metabolism. If both WBC and leuk esterase are elevated, it more strongly suggests a UTI. There are people who have a UA with an elevated WBC without any symptoms. Patients without any symptoms, and no other indication of a UTI on UA could simply have chronic bacteriuria, which means the person chronically has bacteria in the urine.
