LTF test line turned white

[backtothestarting]

My LTF test line turned white, never had this before I presume it's negative?

We have been exposed to covid in recent days and it's rife in the school I'm working at so back testing daily

Do you mean you had a positive line that disappeared? Because that happened to me a few days ago. Faint but clearly visible positive that was there one minute and gone the next. Definitely wasn't seeing things as I had a witness! I've tested countless times since and get a negative every time

Positive line that went or line that is whiter than the surrounding?

It's like the line is there but it's white and the pink is around almost

This picture might be better

Has it been left for the full time? It looks like a flooded or faulty test, so I would do another

How long did you leave it? I find those ones always go like that if left out a while.
