Today I was with other people indoors for a couple of hours. In the unlikely event that I picked up anything when would I expect that to show up on a lateral flow test?
Just wondering when to do a test. Would normally do one on a Monday but thinking Tuesday might be more sensible.
Cheers

Mrs RS says you are unlikely to see any positive result before Weds.

Anywhere between 2 and 14 days after contact, average 5 days, so probably mid-week before it would be detected

Thanks both. I'll do my normal Monday and Thursday routine then. I'm not expecting an issue but it was probably my highest risk activity since it started.

I got "pinged" on Sunday 11 July and did a PCR test on 12/07/21. I was negative and OH positive.
15/07/21 - lateral flow test negative
16/07/21 - PCR test inconclusive (after I was invited to join the pilot to see if doubled jabbed people can avoid isolation, but put into the 'control group', natch).
18/07/21 - PCR test positive. 10 more days of isolation . Still at least OH will be let out soon and can run all the errands.
I don't know if I caught it from the original source (I've felt a bit "off" for the last week, but cold symptoms were more pronounced yesterday, better today). or OH. I now know three doubled vaxed couples where one half has tested positive and the other has subsequently tested positive. My take home is that spending all day every day with someone infected is not a good idea if you don't want to catch Covid.
On the other hand going forward I feel that it's considerably less likely that I'll test positive in the future (or medium term at any rate) just before a looked forward to event, which can only be a good thing.

The LFT detect virus particles in the nasal passages and throat. In order to get enough to detect, you need to be exposed, the virus to infect the bloodstream, replicate, and then re-emerge into the respiratory tract in sufficient numbers to be detected.
As well as a test for being infected, it is probably as much (if not more of) a guide as to whether someone is infectious. Hence it is a usefull tool for screening before admission to a care home etc., but only if done in the preceeding 12 hours or so.
A PCR test, being much more sensitive, should pick up an infection at an earlier stage.
