Comparation of microcolumn gel test and tube anti -globulin test with IgG anti A (B)of pregnant women / 中国基层医药

Objective Compared study on microcolumn gel test (MGT)and tube anti -globulin test (TAT) in the detection of pregnant women IgG anti A (B)in the application of antibody and evaluate the application value of MGT in the prediction of HDN.Methods Choosed blood samples of 443 cases of O blood type pregnant women whose husband were not O blood type as the research object.Every specimen were tested by MGT method and TAT method,and the data were treated statistically.Results The positive rate of MGT method and TAT method were:30% and 12.5% which had statistical significance(χ2 =15.95,P <0.05).The difference was significant in positive cases titer distribution(t =15.13,P <0.01).Conclusion The micro column gel method is rapid,simple,sensitive and repeatable compared of tube anti -globulin test (TAT).

Study of two methods for three hemolytic tests of hemolytic disease of newborn / 中国基层医药

Objective To compare and anlyze the applications of microcolumn gel test (MGT)and the tube anti -globulin test (TAT)for detection of three hemolytic tests.Methods Microcolumn gel test and tube anti -globulin test were used in three tests with a total of 160 cases of blood speciments of newborn who had blood group in-compatibility with their mothers:direct anti -globulin test,free test and elution test,then the data were analyzed statis-tically.Results The positive rates of direct anti -globulin test of MGT and TAT were 30.0% and 12.5%(χ2 =14.64,P <0.05);The positive rates of free test of MGT and TAT were 47.5% and 25.0%(χ2 =17.53,P <0.05), respectively;The positive rates of elution test of MGT and TAT were 62.5% and 30.0%(χ2 =33.99,P <0.05). There was statistically significant difference between two methods in three tests.Conclusion MGT has the advantages of quickness,simplicity,high sensitivity,convenience,needs less sample,high repeatability,direct judging of the re-sults,which is better than TAT in three hemolytic tests.
