ART假阴性比例比较高的。我朋友去年12月确诊康复后，过了半年PCR才是阴性，仅供参考。

Art 是测抗原， 没症状的浓度低可能这辈子都做不出来阳性Pcr灵敏的多

等三个月万一又中了，那不就白等了

如果测到阳性 再测一次阴性交第三次阴性的报告可以吗另外还有一个问题 如果得新冠好了之后 pcr会阳性吗 假如不知道自己得了 pcr能查出来 又不知道什么时候得的 这三个月的期限怎么办

如下 其实小哥哥群里的坡上小护士们也说了他们院也是采取30分界线A separate analysis of a cohort of 73 patients admitted to the National Centre for Infectious Diseases, Singapore demonstrated that SARS-CoV-2 could not be cultured when the Ct value was ≥30, or after day 11 of illness. via National Centre for Infectious Diseases and Chapter of Infectious Disease Physicians, Academy Medicine of Singapore. Period of infectivity to inform strategies for de-isolation for COVID-19 patients, 23 May 2020. Available at: https://www.ncid.sg/Documents/ Period%20of%20Infectivity%20Position%20Statementv2.pdf. Accessed on 23 May 2020. 坡上的阳性标准是小于等于30 兔子的标准是小于37 37-40重测 大于40才是阴性

楼主我给你贴的科普文章看了吗？ 之前别的网友也跟你分享了图片，你看看就懂了

就显示negative，没有数值，这样算是没有抗体吗？Test Result Unit Reference SARS-CoV-2 IgM (ABBOTT) Date Reported: 06 November 2021 02:36:29 Negative A negative test result does not completely rule out infection. Take into consideration that antibodies may fail to develop prior to 14 days of symptom onset, and false negatives can occur in immunosuppressed patients.
