Abstract: Objective To study the effect of time and temperature on the count of peripheral blood cells in newborns.Methods The peripheral blood of 100 cases of newborns who were admitted in the First Affiliated Hospital of Hebei North University from January 2016 to June 2016 were collected,and measured with Sysmex XS-500i automatic blood cell analyzer immediately,then were split into two parts and stored at 4 ℃ and room temperature respectively.The measurement was repeated in 24 and 48 h,and the groups were compared on WBC,RBC,PLT,HGB,IG％ and IG#.Results There were statistically significant differences between the instantly measuring result and those in 24 and 48 h under room temperature (P＜0.05).In case of 4 ℃,the instantly measuring result had no obvious difference with that in 24 h (P＞0.05),while statistical difference with that in 48 h (P＜0.05).Conclusion Newborns' peripheral blood can be stored at 4 ℃C,and the counting results will not be affected for WBC,RBC,PLT,HGB,IG％ and IG# within 24 h.
