During a study of eosinophil-predominant gallbladder disease, an image analysis (IA) technique was developed for quantification of eosinophils and lymphocytes in routine formalin-fixed tissue sections. Alternating sections were stained with hematoxylin and eosin for eosinophils and with monoclonal CD45 antibody visualized with diaminobenzidine by an avidin-biotin procedure for lymphocytes. A protocol was then developed using a commercially available image analyzer and two well-defined macro routines. The system was validated with cell block sections prepared from peripheral blood samples with known eosinophil and lymphocyte counts. The eosinophil counts obtained by this IA technique showed excellent correlation with the absolute counts from a peripheral blood analyzer (r2 = 0.987). The lymphocyte counts obtained by IA showed good correlation with the absolute counts (r2 = 0.820). This IA- based technique provides a sensitive, reproducible, and substantiated means of quantifying inflammatory cells in tissue sections. This rapid and easily learned technique adds quantification as a complementary dimension to the subjective assessment of tissue morphology.
