PYURIA: DEPOSIT IN HIGH‐POWER MICROSCOPIC FIELD—WBC/HPF—VERSUS WBC/mm³ IN COUNTING CHAMBER.

Abstract

Abstract. The methodological study with a defined technique presented in this paper gave the result that the number of WBC/HPF in the sediment corresponded to approximately 11% of the number of cells/mm 3 in the sample. The correlation appears to be satisfactory. Thus the criterion of >4 WBC/HPF for pyuria corresponds to roughly >40 cells/mm 3 under the methodological conditions obtaining here.
