Table 2 Number of correctly/falsely classified avian blood samples (listed according to the avian order and use of the Natt-Herrick Tic® test method for WBC counting). One of the samples was a false positive (leukopenia instead of a normal leukocyte count), and one was a false negative (normal leukocyte count instead of leukocytosis). Overall, this represented 5% of the false results (2 out of 40)
