目的探讨儿童结核菌素试验结果不同时间判定的相关性。方法对428例门诊或住院儿童常规进行结核菌素试验后,分别于24 h4、8 h7、2 h观察并记录结果,建立数据库,采用SPSS 11.5软件进行统计分析。结果 24h与48 h、72 h观察的结果比较P<0.05,差异有统计学意义;48 h与72 h比较P>0.05,差异无统计学意义。结论 24 h结果不能代替48 h及72 h判定结果;在特殊情况下48 h判定结果可以作为72 h判定结果的参考。
Objective To investigate the correlation between children’s tuberculin test results at different times. Methods A total of 428 outpatients or hospitalized children were routinely tested for tuberculin. The results were observed and recorded at 24 h, 8 h, 7 h, and 2 h, respectively. A database was constructed and analyzed by SPSS 11.5 software. Results The results of 24h and 48 h, 72 h were compared between the P <0.05, the difference was statistically significant; 48 h and 72 h compared P> 0.05, the difference was not statistically significant. Conclusion The result of 24 h can not replace the results of 48 h and 72 h. Under special circumstances, the result of 48 h can be used as reference for the determination of 72 h.
