Test result positive, but no trace

A few weeks ago I had been feeling unwell and ordered a test by post.

After 3 days I had an email saying my test was delayed in transit, being delivered via Amazon, I tried to order another but could not as it stated I had already got one. There was nowhere on the site that I could say it had not arrived.

I self isolated for 10 days just incase but do not know if I have had Covid.

I agree,he was sensible to isolate ,but it is so wrong that if people are told they have it and don't they lose time and wages from work
Not everyone in a family catches something others have
My son had swine flu quite badly, none of us, or his wife caught it

The standard test gives (potentially) up to 30% false negative results, so false positives are hardly surprising.

I'm just amazed that so many people put their faith in such a poor test, aren't you?

As the virus is very highly infectious, it's safe to assume that he will have caught it from his wife anyway. Therefore, test or no test, it's sensible to isolate.
