LFT confusion

[Darmy1]

My LFT’s are coming up a faint positive for about a minute then turning negative very quickly, and staying negative.

what does this mean? I have mild cold like symptoms and will continue to test but just wondering in the meantime.

Not sure but the time window has a start as well as an end and you're not meant to read them before then.

Are all the tests from the same box? I had this with one particular box.
As they were negative at the time limit I assumed they were negative. Tests from another box didn't do it

I had no symptoms though, and I might have thought differently if I had.
No one around me caught Covid so I still believe they were negative and it was just an odd dye run

when are you reading the test? you should be going by what it shows at the 15 min mark(or 30 min depending on the brand).

30 minutes as per the instructions
