Results of B-ELISA, I-ELISA and SNT with reference sera.

Note: Coincidence rates between different methods were calculated using Microsoft Excel's CORREL function. The results showed that the blocking ELISA and the SNT have a positive coincidence with coincidence rate of 70.6%. The coincidence rate between indirect ELISA and blocking ELISA was 0.35, and the coincidence rate between indirect ELISA and SNT was 0.44.注：不同检测方法间的符合率采用Microsoft Excel的CORREL函数进行计算。结果显示，阻断ELISA（blocking ELISA）与SNT的阳性符合率为70.6%。间接ELISA（indirect ELISA）与阻断ELISA的符合率为0.35，间接ELISA与SNT的符合率为0.44。
