The Cobas® u701 and URiSCAN® PlusScope did not display the quantitative bacterial counts when our experiment was conducted. The iQ® 200SPRINT provided ASP values instead of bacterial counts.
Abbreviations: white blood cell; ASP, all small particle; GPC, gram-positive cocci, not specified; CNS, coagulase-negative staphylococci; GNR, gram-negative rods, not specified.
