No. The leukocyte test pad on the reagent stix has a sensitivity of >10WBC/uL.  Therefore, while there may have been some WBCs present, there was not a sufficient number to cause a positive reaction on the reagent stix.  A similiar type of thinking can be applied to the nitrite pad to explain the negative nitrite result even though bacteria were seen.  The nitrite pad requires 100,000 organisms/mL for a positive result to be given.  20-30 bacteria/hpf are not sufficient to give a positive result on the reagent stix.
