Abstract:
OBJECTIVE:To detect the ABO / RhD blood type of infants younger than 6 months in different gestational age and month old with automatic microcolumn glass sphere and tube method, and compare the result of the two methods.
METHODS:The data of 896 samples of infants younger than 6 months from January 2018 to February 2019 was collected. The two methods were used to detect ABO/RhD blood type in all samples and compare the detection rate of ABO/RhD antigen and ABO reverse typing and agglutination intensity of the two methods.
RESULTS:Three hundred and eight cases of type A (34.4%), 281 cases of type B (31.4%), 210 cases of type O (23.4%), 97 cases of type AB (10.8%), and 896 positive cases of RhD blood type were detected out by two methods. There were no significant differences of ABO/RhD antigen agglutination intensity between two methods (P > 0.05). Except for type AB, the detection rate of ABO reverse typing in infants with type B was significantly higher than that with type A and type O (P < 0.05). The agglutination intensity of type A reverse cell was higher than type B reverse cell (P < 0.05). The fully automatic microcolumn glass sphere method exhibited higher detection rate of ABO reverse typing in the samples of type A and type O group and agglutination intensity of ABO reverse typing in all types as compared with the tube method (P < 0.05). The detection rate and agglutination intensity of ABO reverse typing in term group were significantly higher than those in preterm group (P < 0.05). The fully automatic microcolumn glass sphere method exhibited higher detection rate of ABO reverse typing and agglutination intensity compared with the tube method between two groups (P < 0.05). The detection rate and agglutination intensity of ABO reverse typing in group IV (4-6 months old) were significantly higher than those in groups I, II and III (young than 3 months old) (P < 0.05). The fully automatic microcolumn glass sphere method exhibited higher detection rate of ABO reverse typing in I, II, III groups and agglutination intensity of ABO reverse typing in the 4 groups compared with the tube method (P < 0.05).
CONCLUSION:ABO / RhD blood group antigen can be accurated detected in majority of infants, but the detection rate of ABO antibody is related to gestational age and month age of infants. The detection rate and agglutination intensity of the fully automatic microcolumn glass sphere method in ABO reverse typing are higher than those of the tube method, especially for premature infants and children within 3 months old.
