Quantitative counts were obtained for bacteria (BACT channel, counting particles with diameter [greater than or equal to] 2 [micro]m), RBCs, white blood cells (WBCs), casts (CAST channel; gated to detect mainly inclusion-bearing granular or cellular casts because hyaline casts are difficult to discern from slime threads with such an analyzer), large epithelial cells (ECs), and small round cells (SRCs; including both epithelial and inflammatory cells).
