covid 测试not detected和negative 区别

天韵

我和女儿周一同时去做的测试，为什么女儿的短信是not detected而我是negative？知道肯定都没有感染，但是这俩有什么区别吗？
难道是手动发短信，发短信的不是同一个人吗……

不知道，免责猜想是不是孩子当时检测的时候，获取的剂量不够，所以没有检测到？

应该不是。我老公也去测了，他也是not detected，但是我的结果是negative。

那就只能自己安慰自己，是两个不同的人或者测试人员发的短信。

只能想打字员选错下拉菜单了。不过还好没选“positive”

每天十四万的测试量不可能真的是人工短信吧……

听起来像是系统里有三个选项 positive ，not detected，negative。

至少要有人把结果输入储存检查结果的系统里吧。

女儿没打过，但是我老公打过。他俩都是not detected。

A result of “Not Detected” indicates that SARS-CoV-2 viral RNA was not found in your biological specimen that was submitted for testing. This means it is very unlikely that you had a COVID-19 infection at the time you took this test.

However, there is a small chance (less than 5%) that this test produced a false negative, meaning that the test indicated that you do not have an infection when you actually do.

A false negative can occur if:

• Your exposure to COVID-19 was recent
• Your viral loads are so low that they were unable to be detected by the test
• Your specimen was not collected properly as per the instructions given
  

In very rare cases, a false negative can occur if you are infected with a strain of SARS-CoV-2 that has undergone a mutation . This is not necessarily cause for concern. Most mutations have little to no impact on the severity or contagion level of a disease.

谢谢！不过感觉这个讲的是not detected和false negative。难道测试结果的negative意味着false negative？那感觉不make sense啊。
