Effect of Microbial Culture and Rapid Serological Test in the Diagnosis of Mycoplasma Pneumoniae Infection in Children
Objective To study the effect of microbial culture and rapid serological test in the diagnosis of mycoplasma pneumoniae infection in children.Methods A total of 102 children with suspected Mycoplasma pneumoniae infection who were diagnosed and treated in our hospital from August 2021 to July 2023 were selected as the research objects.All of them were subjected to microbial culture and rapid serological tests.With blood culture as the standard,the diagnosis of different test methods,the positive detection rate of different ages and course of disease,and the diagnostic efficacy of different test methods were compared.Results The positive diagnosis rate of microbial culture for mycoplasma pneumoniae infection in children was higher than that of rapid serological test(P＜0.05).The positive detection rate of mycoplasma pneumoniae infection in children under 3 years old and 3-7 years old by microbiological culture was higher than that by rapid serological test(P＜0.05).There was no significant difference in the positive detection rate of mycoplasma pneumoniae infection in children over 7 years old between microbiological culture and rapid serological test(P＞0.05).The positive detection rate of mycoplasma pneumoniae infection in children with a course of disease≤7 d was higher than that of rapid serological test,and the positive detection rate of children with a course of disease＞7 d was lower than that of rapid serological test(P＜0.05).The sensitivity and specificity of microbial culture in the diagnosis of mycoplasma pneumoniae infection in children were higher than those of rapid serological test(P＜0.05).Conclusion There are differences between microbial culture and rapid serological test in the diagnosis of mycoplasma pneumoniae infection in children.Among them,microbial culture has higher diagnostic value and is worthy of clinical application.
