These have a much higher false negative rate than the PCR tests, but are much faster than them. If you've been exposed and develop symptoms you definitely want the PCR test.
I hope they were wearing masks and distancing Durhamlad. Fingers crossed he and his coworkers stay healthy. This is why the push to return to pubs and offices too soon is not wise, it is still circulating too much.
Thanks margo, I agree that lateral flow tests are not as sensitive as PCR tests and if our son develops symptoms he will be given a home PCR test like my sister was, when she developed symptoms and was confirmed as having Covid just before Christmas. She caught it from work and all 6 in her office caught it at the same time even though they were socially distanced, wore masks and had Perspex screens around their desk and kept a window or 2 cracked open.
I don’t think our son’s office is nearly as well planned out although they do wear masks, and they only have one window so we fear the worst, the next few days will be critical. If he does catch it we hope that his age, in his 30s, works in his favor.
