The comparasion of effect between Thermal elution test in 56 ℃ and Freezing thawing test in -20 ℃ for neonatal ABO haemolytic disease / 国际检验医学杂志

ABSTRACT

Objective To compare the effect of two experiments-Thermal elution test in 56 ℃ and Freezing thawing test in -20℃ for ABO haemolytic disease in neonates.Methods 74 samples of neonatal blood with anticoagulant EDTA-K2 were collected.Di-ana card method was used to compare the difference of the two experiments.Results 66 samples were positive and 8 were negative in 56 ℃.Meanwhile 52 were positive and 22 were negative in -20 ℃.There was significant difference between the two methods (P<0.05).The positive coincidence rate in 56 ℃ was obviously higher than that in -20 ℃.Conclusion There is difference in detec-tion effect between Thermal elution test in 56 ℃ and Freezing thawing test in -20 ℃ for neonatal ABO haemolytic disease.
