What's the chance of 3 negative lateral flow tests being wrong - does anyone know? I saw PP mention something about 5 tests but wasn't really sure what he meant.

LFTs are ok if done at the right time. They are accurate I think if you’re doing them to make sure you’re not carrying any infection if you are intending to visit someone or go to an event, but have no symptoms. I think that once you have any symptoms at all they don’t then pick it up so shows negative. I’ve had friends that are in jobs which require LFTs all the time....

They were saying the opposite this morning, netty. That if you have any symptoms, you would get a false positive?

PP mention 5 tests - - yes do 5 tests and then your technique approaches a PCR ( clearly wiping the dogs nose, or not taking a sample doesnt count )

[ That if you have any symptoms, you would get a false positive?]

a false positive is that you DON'T have the disease BUT you have tested positive. symptoms irrelevant

SJ: the chance of 3 negative lateral flow tests being wrong
Here testing negative three times and having the disease is very very slight

My sister in law had 2 negative LFTs and her colleague one, both tested positive on a PCR

Feedback - I was given antibiotics for the bug (which is pretty much the worst bug I have ever had) I told the doctor about my 3 LF tests and she confirmed that you shouldn't use them if you have symptoms. PCR test result has just come through as negative on my phone so that's good.

Glad you got a negative, now I hope the antibiotics kick in very soon.
