To measure the reliability of the manual differential leukocyte count, replicate blood smears from twenty specimens were distributed to fourteen medical laboratories in central Kansas. Analysis of respondent data using the chi-square test of independence revealed for 40% of the specimens, results were dependent upon laboratory. A “differential leukocyte scan” regimen is proposed as an alternative to the current methodology. Also, comparison of lymphocyte percentage reported by the hematology analyzer and the mean lymphocyte percentage of the replicate differential leukocyte counts revealed a strong positive correlation. This indicates automation is another alternative.
