White Blood Cells per High Powered Field. A term used to denote the number of white cells within a urine sample (A Urinalysis, or UA). The normal range is 0-5 wbc/hpf
If there a an elevated white blood cell count in the UA, it might be because there is a UTI, however it also could mean that the urine is simply more concentrated than normal. The UA also consists of other markers including the Leukocyte Esterase (LE) that helps to give more evidence that an elevated WBC/HPF is a true marker for a UTI and not the result of something like concentrated urine.
