Normal ranges were determined in 8-week-old unaffected dogs and are as follows: neutrophils, 8500 ± 2900 cells/μL; monocytes, 1400 ± 700 cells/μL; lymphocytes, 5000 ± 1500 cells/μL; CD3+, 76.2% ± 14.4%; and CD21+, 12.9% ± 8.6%. The percentage of GFP+ cells in untreated control dogs (background signal) was less than 0.05%.
To convert neutrophil, monocyte, or lymphocyte counts to × 109 cells/L, divide cells/μL by 1000.
