就是这个意思 现在新加坡开展的测试 特异性远远高于灵敏性就是漏掉阳性比例会远远高于被冤枉成阳性的比例 https://zh.wikipedia.org/zh-cn/%E9%9D%88%E6%95%8F%E5%BA%A6%E5%92%8C%E7%89%B9%E7%95%B0%E5%BA%A6 特异性和灵敏性这里说的很清楚，英文更简洁 Laboratory tests are characterized by their ability to detect a positive case (sensitivity 灵敏性) and their ability to determine a negative case (specificity 特异性). https://www.ace-hta.gov.sg/public-data/covid-19-resources/PCR%20testing%20for%20COVID-19%20-%20where%20to%20swab%20(24%20April%202020).pdf 这个数据，swab test特异性是100%，你没有新冠就100%是阴性结果，根本就不会冤枉你。 测了20个样本就申报结果？故意搞笑的吧？
