Meant the picture, not the link.

Will edit.

Gotcha

The ex got it, so we are all off getting tested today just in case our son who goes back and forth caught it at theirs.

None of us feel weird, so hopefully we escaped it. Ah well, it was only a matter of time really... not ideal if son has it or we do as the exams at school are next week :/

EDIT we all tested negative. (Phew) Ex and missus are proper sick from it but double jabbed so hopefully no complications for them.

we all tested negative

Glad to hear that, hope the ladies recover quickly.

Preaching to the choir here, but even PCRs can give out false negatives (≈9.2% in one small study from Feb 2021, published in either Virology or BMJ). Please consider using a mask, avoiding crowded spaces, and not snogging any old people for a couple of weeks. 😉

My eldest has a positive LFT. Will she get a positive PCR or a series of negative ones like my youngest managed ~5 weeks ago?

She does seem more lurgy filled that my youngest. Wonder if I'll get it this time round?

My and the husband feel old so the no snogging old people bit is going to be tricky ;P

Wow 9% false negative? We have no symptoms of disease but will keep an eye out, we always wear a mask and I have a box of LF tests.

The Christmas work do is in 3 weeks...if there's any doubt I will get a PCR test. Because it's all inside... :(

The major cause with false negatives is that people don't swab correctly.

But that is neither here nor there stay safe old person snigger.

EDIT:snogger is auto corrected to snigger.

The major cause with false negatives is that people don't swab correctly.

It’s certainly an issue with the dichotomous lateral flow tests which only read out yay or nay, and don’t indicate if a swab was sufficiently swabbed (eg, by testing for the presence of a related enzyme). The study I’m thinking of was done in Canada on samples taken at a regional hospital, iirc. That’s not to discount human error entirely, but the likelihood is lower. It’s not the only study indicating that available testing methods aren’t unerring (NY did a massive study but I don’t recall if it was for PCR tests).

Positive PCR test for my eldest. She isn't going anywhere for a bit. My youngest and other half are negative. My test result is yet to arrive which is strange.

Can anybody tests differentiate between covid developed antibodies and vaccine developed antibodies? Anyone know of a paper on this?

the ONS survey one i did a few weeks back was able to tell the difference between infection/vaccination but only with a 6 month confidence window.

How do find that out? My monthly ONS blood testing for antibodies just comes back with "positive" each time and no further details.

Yes, an Anti-N test will only test positive if you have natural immunity because they look for nucleocapsid molecules.

Anti-S tests look for spike proteins. Covid vaccinations are based on the spike protein so they can't tell the difference between natural infection and vaccination.

Are you feeling OK otherwise? Or think you got it too?

I'd say keep testing, my daughter tested positive last Friday, her mum has to do LFTs daily for work and only changed to positive yesterday as did a younger sibling

Thanks, enough there to find a paper myself.

My PCR came back negative about an hour ago.

Apparently I'm suppose to enter the negative result into the app. How does that help anyone? Why would I want to do that? If I'm being paranoid the app doesn't currently know who I am but that changes if I put a test result in.

I think I've had a cold for about a week. A couple of LFTs during that time both negative.

Why would I want to do that?

It helps with quality assurance data for the testing services amongst other things.

It helps with quality assurance data for the testing services amongst other things.

In what way?

Maybe it helps calculating the % of people that can infect each other in a household?

IDK how the English app works though. The NI one only asks you for positive PCR tests.

Exes missus dad also tested positive now, luckily he has no symptoms. Ex/another kid in household waiting on results.

Sorry it was a ZOE study for antibodies.
got confused, i did an ONS swab test a while back

In what way?

Google it. I am getting my information from the NHS Scotland web site. Both England and Scotland insist that reporting negative tests is important, both for PCR and LFD. I don't personally feel any privacy concerns about doing this.

They know I have a negative PCR result, this isn't like reporting a negative LFT. I'm failing to understand why entering my negative PCR result into the Covid Bluetooth beacon app helps anyone.

By linking a test result to the app, the app can give you the most relevant guidance.

I don't need any further guidance, I've already been told I don't need to isolate because I'm double jabbed etc. If I put a positive test result the app would notify my close contacts but it isn't going to do that for a negative. So what's the point?

(I've had a Google, my search terms haven't turned up anything useful - perhaps you have something?)

Someone has pointed out it might have an impact on the app and contacts identified via it if I had been pinged by the app.

Anyone had booster yet? Side effects? Have mine tomorrow and also Flu jab they may do at same time...
