Study on the rule of microscopic examination for mononuclear cell in blood of pediatric patients detected by CD-1700 hematology analyzer

Objective To study the rule of microscopic examination for mononuclear(MO) cell in blood of pediatric patients detected by the CD-1700 hematology analyzer and assure the quality of blood routine examination. Methods MO cell in 232 pediatric patients was determined by the hematology analyzer and microscopic examination of the blood smear. Results If MO cell level was10%,there was no significant difference between the microscopic examination and instrument analysis.If MO cell level was≥10%,there was significant difference between two methods,and 15.5% sample with abnormal cell was detected by microscopic method. Conclusions It should make the microscopic examination when the level of MO cell is over 10% by hematology analyzer,in order to detect the abnormal cell such as atypical lymphocyte,eosinophil cell,immature cell etc.
