1
Cell data are the percentage of each type based on the total count. H/L 1 and H/L 2 are 2 different methods of calculating heterophil to lymphocyte ratio.
2
AV = aviary; CC = conventional cage.
3
Typ, Var, Classic Het = typical, variant, and classic heterophil, respectively; Lymp = lymphocyte; sm = small; med = medium; NK = lymphocyte with azure granules; GBlast = gramuloblast; Mono = monocyte; Baso = basophilic granulocyte; Eosin = eosinophil.
4
TWBC for hen #749 CC was calculated from microscopic fields located at the slide center only (100 K) and by including fields at the edges (180 K).
