Negative LFT after positive

[Aurorie11]

DD (age 11) tested positive on Monday, she's just been feeling a bit tired.
Out of interest got her to do another LFT about an hour ago, which is negative after 2 days.
Looking for similar experiences, is she likely to go positive again?
Not looking to break rules, will test on days 5 and 6, but curious

Could be a false negative as they don't pick up a positive all of the time

My 11 year old dd was exactly the same. Tested negative 24 hours after testing positive and never tested positive again on daily tests. I can only conclude that she had had it a few days before she had the positive test, that she had just had it really mildly or that it was a false positive result. I was told you couldn't have a false positive but a colleague tested positive on LFT but then negative on a PCR so who knows. She did have a sore throat for a day so I do believe that she was positive at the time of testing.

@Theresomethingaboutdairy thanks, we had been daily testing in the lead up to Monday's positive due to be alerted to close contact. She said she's just been feeling tired so I think she's had it but just mildly.
Did the rest of your family catch it?

I tested positive on Monday (had a headache) but have tested negative since then. Am isolating but also wondering whether it was a false positive or just had it very mildly?

@Aurorie11 she is the third of 4dc, so six of us in total in the household and, no, nobody else caught it. Fingers crossed for you.

I tested positive on a lft yesterday then confirmed with pcr. I did another lft today (my daughter is autistic so I did one alongside her to help) and it's completely negative.

Im still going to follow the guidance and assume the pcr is correct but its very odd

LFT miss a lot of positive cases so it’s not a surprise.

I get that there are false positives, but rules now negative on day 5 and 6 and can end isolation early. Has any one had a positive then negative 2days late and subsequent positive?

It would be possible - just because one LFT picked up your infection, it doesn’t mean that another LFT would. That’s how inaccurate they can be.

Eg someone I know tested negative on one LFT then positive on another, from the same packet, on the same day!

We are saying its more likely to be a false negative result than a false positive result and thats why you're asked for 2 consecutive negative results to come out of isolation rather than just 1.

So false negatives are the issue, not false positives.

The new rule is silly because the tests aren’t accurate enough. It’s a sly way of getting people to continue to isolate for the original 10 days and giving the illusion of freedom.

Day 2 and now day 3 negative, keeping fingers crossed for 5 and 6

@Iggly I took 3 all within 10 mins one time before doing a fit2fly one, the first was a very quick positive, I was in such disbelief, so I took another, which was negative, then my fit2fly which was a quick negative.

I think when you get those super quick positives but have zero symptoms, it is best to take another right away.

Do you think it's connected to viral load then? I have been confirmed by pcr so will be isolating regardless but have been testing regularly alongside autistic DD (as its the only way I can get her to test) and my lft tests have been negative since the day after my pcr!

I don't have many symptoms so far only a sore throat on the first day and thats the only day i've had a positive on a lft

Why are people testing themselves so much? Positive, just isolate and test on day 5 and 6 and hope for negatives then. 🙄

@FajitaBonita
I agree, my son got a positive Monday evening and people are texting me asking how he is and if he’s still getting positives? He’s only on day 3 so why would I have tested again, wasnt going to until the weekend days 5 and 6 to check if he’s good to go back to school Monday.

My DD was negative from day 2 and still negative day 6, so back to school
I've now got it
