Abstract:
Objective To establish normal range of components of cord blood cells in healthy fetuses from 19 to 37 weeks' gestation and to provide proof for diagnosis of hematological disorders in prenatal fetuses and premature infants.Methods Twelve hematological parameters were determined in 182 fetuses using Coulter GENS system 2 full automated blood cell counter,and the blood cells were classified by microscope.Results The number of white blood cell(WBC) was increased gradually from 3.58?10~9/L to 5.76?10~9/L with the gestational weeks increasing from 19 to 37 weeks.The differential counts indicated that the lymphocytes represented the main population.The number of lymphocytes and normoblast was decreased gradually and that of neutrophils was increased gradually.The numbers of monocytes,eosinophils and basophils remained stable as the increasing of gestational weeks.The red blood cell(RBC),hemoglobin(HGB) and hematocrit(HCT) were increased gradually but mean corpuscular volume(MCV) was decreased.The differences between mean corpuscular hemoglobin(MCH),platelet volume distribution width(PDW),mean platelet volume(MPV),plateletcrit(PCT) and mean corpuscular hemoglobin concentration(MCHC) were not significant among different fetuses' ages.Conclusion The components of cord blood cells in healthy fetuses are dynamic and the establishment normal range of components of cord blood cells in healthy fetuses is helpful to diagnose the disorders in prenatal fetuses and premature infants.
