If you've done a lateral flow test

[catwomanhatwoman]

A) Have you or a family member had a false negative? (my son has)

B) Have you have had a positive result?

C) If you have had a positive result was it clearly positive before the 30 mins it says to wait to read the result?

Mine was faint positive within a minute - got darker within 3 minutes - despite me shouting no repeatedly

Not had either so far 🤞 3 of us are doing them twice a week

Been doing them twice a week last few weeks and had no positives.

Not had any positives. No idea if any false negatives as wouldn’t know it was false without symptoms and another test.

All those who tested positive at DS school last week had the positive lateral flow test confirmed as positive with pcr tests.

All negatives so far.

All negative so far and also doing weekly pcr testing with ons study which have also been negative (4 of us).

despite me shouting no repeatedly

Been doing them twice a week for school (teacher) all negative as well as negative PCR we all had to do be suse of done positive (asymptomatic) pupils.

4 family members do them twice weekly. All valid negatives so far bar one invalid test.

All negative tests for me and my DD so far

Twice a week here as well plus more if i am travelling - all negative. I am supplemented by PCR test

Twice a week tests, all negative so far.

Done lots in the family, all negative. Seen lots done at work, positive ones showed up almost at once and just got darker as the time passed.

A) yes
B) yes
C) DS1 yes, very strong line within minutes. DS2 no, very faint line by 30 minutes, followed by positive pcr the same day

As far as I'm aware, there is no such thing as a false positive.
I'm a Covid tester. Even a faint line is a positive. You only ignore if it's been more than 30 minutes since you dropped the fluid in the well.

All negatives.

All negative for me and dd1

a) yes husband negative LF, positive PCR
b) yes son
c) line appeared very quickly, could see it appearing within a minute or so of the fluid flowing over the area.

We’ve done umpteen here. All negative within seconds apart from one invalid test where nothing at all showed up.

A false positive is when the test says positive, but pcr is negative. It is a thing. Nothing to do with how strong the line is.

No idea if we've had a false negative - but noone has been symptomatic since we started doing LFT.

Not had a single positive result in 2000 school LFT, so no idea how quickly the line would come up. Sorry.

I personally haven't had a positive from any of mine but of those who I know that have, the result came up immediately.

I highly doubt the test is designed to change its mind at the very last minute leading up to the half hour. Negative or positive, the result is established pretty quickly during the testing process.

My friend tested negative on the same day her husband tested positive - was positive for her the next day (and confirmed by PCR).

All negatives, no false positives

MIL had a strong positive showed up within 3 minutes, she had no symptoms and confirmed positive by PCR

My family have all been doing them twice a week for a while and had no positives. The result always looks very clear after a couple of minutes but I always wait half an hour before reporting.
