Objective: To establish the reference range of 6 reticulocyte parameters. Methods: With Sysmex XE-2100 hematology analyzer,we randomly studied 172 cases of healthy adults(half male and female) on reference ranges of reticulocyte ratio(RET%), reticulocyte count(RE#), immature retics fraction(IRF), low fluorescence ratio(LRF), middle fluorescence ratio(MRF) and high fluorescence ratio(HRF). Results: RET%: male(age 21~51) was 1.20±0.36,female(age 20~49)1.12±0.31,there was no significant difference between each age groups(P0.05), unite RET% 1.16±0.34 (0.48~1.84); RET#(×109/L): male 60.1±18.9 (22.3~97.9),female is 50.1±14.0 (22.1~78.1), there was significant difference between each age groups(P 0.05); IRF: male is 5.7±2.8(0.1~11.3),female is 4.6±2.3(0~9.2),there was significant difference between each age groups(P 0.05); on LRF,MRF and HRF, there was signficant difference between each age groups on LRF and MRF(P 0.05),except HRF(P 0.05), unite LRF% is 0.4±0.4 (0~1.2). Conclusions: There is no significant difference between reference ranges of 6 reticulocyct parameters with some references. But sex, analyzer and so on are correlated with the counting results of reticulocyte parameters, so the establishment of this reference range is necessary by laboratory itself for the operation of laboratory and clinic study.
