Im still testing once a week, my last lateral flow was positive, followed it up with a PCR test which was negative, then I started to get symptoms, we’re talking within a day of the negative PCR. Took another lateral flow test, again it returned a positive result. Since then I read a Guardian report that this is happening a fair bit and the powers that be are looking into it.
It could be a cold that the Lateral flow is picking up, a dodgy batch, or something else. Ive decided to isolate for 10 days just to be caredul.
