Abstract:
Objective To investigate the application values of 3 kinds of crossmatching method saline medium method,polybrene test and microcolumn gel test in the neonatal blood transfusion security.Methods 174 newborns needing blood transfusion were simultaneously performed the isotype crossmatching by the saline method,polybrene test and microcolumn gel test.The irregular antibody and the direct antiglobulin test were routinely conducted,the samples with positive irregular antibody were further per-formed the antibody specificity identification.Results 14 cases (8.05%)of crossmatching incompatibility were found by the saline method,1 case (0.57%)by the polybrene test and 62 cases (35.63%)by the microcolumn gel test;among which,31 cases were secondary side crossmatching incompatibility caused by positive direct antiglobulin test,1 was the incompatibility of 3 methods caused by anti-D antibodies.The difference between the polybrene test and the microcolumn gel test was of statistical significance (P <0.05).Conclusion The blood crossmatching by the microcolumn gel test in blood transfusion of newborns requires quite few amount of blood sample,is simple to operate and easy to be standardized.With results clearly and easily measured and sensitivity higher than that of polybrene test,its result is clear and easy to be judged,its sensitivity is higher than that of the polybrene test, which has the important significance for ensuring the neonatal blood transfusion safety.
