Firstly happy new year all.
I regularly test for work, every 2-3 days. Recently I have had a couple of occasions where I’ve noticed a very faint second line. The first time I noticed this I isolated, called in sick to work and waited for pcr. It came back negative thankfully but since then, I’ve had another two very faint lines when testing. When I’ve taken another test to be sure, there’s no second line visible so I’m confused. To be clear, I’ve had no symptoms what so ever nor have I been a contact of someone who has tested positive. I’ve tried researching online why this could be happening. I’ve ordered another pcr to be sure. Has this happened to anyone else? Am I doing something wrong? Surely it’s pretty impossible to get wrong! To add, I don’t leave the test longer than 30 mins, I always set a timer so I know that’s not the issue. Going mad here! TIA
