ABSTRACT
Objective To study the IgG antibodies on red cell surface in ABO and Rh-incompatible infants and to evaluate its predictive value for hemolysis. Methods From Nov. 2001 to Jul. 2002,50 full term newborn babies with ABO and Rh incompatibility hemolysis were admitted .They were divided into two groups according to the direct Coombs test(DCT) 38 cases with positive result and 12 cases were negative. Another 30 normal newborns were chosen as control group. Erythrocyte associated IgG,A and M were measured by a flow cytometry (FCM). Results the mean level of concentration of IgG antibodies in positive DCT group was (12.64?16.83)%,while (4.54?2.54)% in negative DCT group ( P 427.5 ?mol/L,IgG was elevated with the increased TSB level. There was a close relationship between the concentration of TSB and IgG ( r =0.678). Conclusion Measurement of erythrocyte surface antigen IgG assists the diagnosis of maternal-fetal incompatible hemolysis,especially when with a positive direct Coombs test result.
