本文以公认的捕捉法ELISA检测HFRS血清中的特异性IgM作金标准,观察考核了123例HFRS患者口腔软腭出血点(软腭出血点)的阳性率。结果在123例HFRS中,软腭有出血点112例,阳性率为91.06,捕捉法ELISA检测血清中特异性IgM阳性119例,阳性率为96.75%,两个阳性率比较,P>0.05,无显著性差异。软腭出血点敏感度92.44%,诊断符合率91.06%,阳性预测值98.21%,假阴性7.56%,结果提示软腭出血点的出现对HFRS早期诊断有很大参考价值。
In this paper, we use the accepted capture ELISA to detect the specific IgM in HFRS serum as the gold standard, and the positive rate of oral soft palate bleeding (soft palate bleeding) in 123 cases of HFRS was observed. Results In 123 cases of HFRS, there were 112 bleeding spots in the soft palate, the positive rate was 91.06. The positive rate of the specific IgM in serum of 119 cases was 96.75% by ELISA, and there was no significant difference between the two positive rates (P> 0.05) Sex differences. Soft palate bleeding point sensitivity of 92.44%, the diagnostic coincidence rate of 91.06%, the positive predictive value of 98.21%, false negative of 7.56%, the results suggest that the emergence of soft palate bleeding HFRS early diagnosis of great reference value.
