Anyone had positive LFT but negative PCR??

I'm in this weird no mans land with my teen dd who has been unwell this week with all the CV symptoms. Have done several LFTs which are all positive however she's had two PCRs which were both negative.

Are PCRs reliable?

I'm v confused by the discrepancy.

you can get a false negative on a pcr.

My sons friend did, had symptoms, several positive LFT and 2 negative PCRs. His mum also tested positive on a PCR a few days later.

I had a positive LFT 2 weeks ago and booked in for a PCR. Did a few more LFTs while waiting for results and all 4 had positive lines, some more faint than others but all 4 definite lines. PCR came back negative so went back to work. It was weird but that's the guidance.

I'm sure my dd has CV, her school have nearly 300 cases so it would make sense. She's had the high temp, aching bones, severe headache and change in taste. LFTs still positive this morning...

I think I'll book her another PCR next week.

Someone tested things that give a false positive.
Vimto, Tomatoes, a few citrus fruits, look it up.

Yes, my DS and one of his classmates that I know of had this last week. Did another LFT after which was negative so I'm assuming that's that. I don't understand how that happened but he's gone back to school.

Oops I just posted about same thing sorry! Yes happened to us this week. Storing positive laterals for ds and negative PCR. He's symptomatic. And negative both types of tests for 3 other in hosue who have had mild symptoms such as tiredness headaches etc. I don't know what is going on. Very weird.

Same thing in our house. Teen DS a strong positive LFT on Sunday. DS2 had temperature that afternoon. Negative PCRs for all on Monday. Teen lost sense of smell on Tuesday. All of us have vague malaise, off food, headaches etc. Re-did PCRs on Thursday because he'd lost his sense of smell and still negative. Can't work out if it's Covid not being picked up by PCRs or a different bug that's somehow caused the positive LFT. I've kept them both off all week anyway as they've not been particularly well but I guess they'll be back on Monday.

Yep! I’m not feeling well, had 3 positive and two negative LFT’s (2 positives upon waking, so no food or drink beforehand and all tests over 30 minutes after anything to eat or drink), 1 negative PCR and called NHS who told me they think PCR is wrong . I’m awaiting the results of the second PCR.

Another one here ds was really ill last week headache, achy bones and high tempreture. Pcr was negative. Went school as the guidance says. Still has a cough and 3 very faint positives some more faint than others but there so now waiting on another pcr.

Miracle29 · 02/10/2021 23:30

Well ds pcr came back negative again and I'm confused. He had a pcr on day 3 of symptoms negative now we are on day 9 and pcr negative again. In the meantime of waiting on pcr I did another lft and positive again. I did a lft on myself and it's a pure negative no line at all so not a dodgy batch.

CurlyhairedAssassin · 02/10/2021 23:39

Yes similar issues here. DH and I both postive in PCR, only him positive on lateral flow. Teens both negative on both LFT and PCR. We’ve all had exactly the same symptoms. DS2 is still coughing, he will be going to school on Monday with his cough if his lateral flows all stay negative. I can’t keep giving him PCRs. But I’m not sure they’re doing their job at the moment anyway….
