Question for those who always test positive on flow flex

[CliveThighs]

Since Dec every single flow flex lft has been faintly positive (I've had several negative pcr tests done).

However, dh has now tested positive after some kind of super spreader work meeting. I have a couple of the old style throat swab lfts and I'm getting a faint line on them (no symptoms, only tested as dh is positive).

So people with the positive flow flex tests, were you consistently negative on other brands? Or did they come up positive too. Because I'm being haunted by faint lines.

I am consistently negative on all of the other brands that I have used.
Nearly always faint positive on flowflex.

Might be a god idea to isolate today and take another test in the morning. When I actually got covid my line got strong by the evening.

My DH is always faint line flowflex but negative on the old style ones with long sticks.

I've just had my pcr results back from yesterday. It's positive.

And my lfts are now properly positive too, the faint ghost line has become a chunky thick definite line (picture is of my last 3 days of tests lined up)
