LF test and PCR test

[Yellowmellow2]

Positive LF test yesterday. Went for PCR. Has just come back negative. No symptoms. I assume I just carry on my merry way and ignore the LF result?

Aparantly so. Are you in the SW of England?

Yep.

No, London. It was one of the newer tests that you just do in your nose. Strong second line.

Technically yes but a false positive on LFT is very rare. There are a lot of reports of false negative PCRs at the moment. Personally I would assume its covid. You can do another PCR again in a few days to check.

I agree with this. If at all possible i'd be isolating as it's very likely you have Covid.

My DD had 3 positive LFTs and 2 negative PCRs. I’ve heard of quite a few people it’s happened to since.

Really weird.

Oh. Just been to see my elderly mother as assumed ok. What shall I do? Another PCR and LF?

Hopefully it's all fine but yeah I'd get another PCR test.

Try another LFT

Then a PCR in a couple of days - what is your work policy on tests?

I’m a teacher so regular lateral flows anyway. Mmmm, wonder if I should go to work or not? Why does it have to be so confusing?!

I think gov and my work place say yes but my head says "of course not don't be silly"

I am the head 😂😂

Now this is going bit crazy. Have done two of the new up the nose LF tests and both are positive. Done one nose and throat LF test and it’s negative, and a negative PCR. How am I suppose to interpret that 🤷‍♀️

That’s definitely positive isn’t it??

Haha I meant my brain!

Yeah! Omg that's so weird. Maybe you only have covid up your nose?

False positive rate for lfds is approx 1/1000. Do a second lfd (from a different box if possible to rule out a dodgy batch) and if positive then 2nd pcr and isolate. If no symptoms and 2nd lfd negative then assume you are the 1 in a 1000 and carry on as normal but do a daily lfd for the next few days just incase and distance from other staff at school (especially dsls/slt) just incase.

*Cross post, sorry.

Definitely 2nd pcr but if that is negative and no symptoms then go in to work as normal

It's a confusing thing at the moment

So random!

Personally I'd assume I had covid and have another PCR in a couple of days (and maybe just swab your nose )

Same thing happened to ds (12). No symptoms and only positive on the new lfts. Old lfts all negative (he has now done 5 of each). He's isolating and waiting for PCR results. Very bored and still completely asymptomatic 4 days in!

That’s very funny @BlanketPiggy 😂😂

All too confusing. Maybe I’ll just go and do another PCR now to be sure.

DB took a week before he tested positive on a LFT and PCR.

I read an article the other day that said they're seeing lots of this- positive LFT's then a negative PCR- so they advised people to assume it's covid despite the negative PCR and isolate anyway. It seems that many people (not all) were then getting a positive PCR a few days later.

But I’m only getting positive on the up the nose tests (twice), not the nose and throat test which are negative (twice) 🤷‍♀️🤷‍♀️
