Has anyone ever had a LFT with a double control line?

It was more obvious before it dried out.

I don’t think that’s a true line, I think dye run has caught a join below one of the fixture points.

If you can catch one of the cassettes in the right light you can loosely see how they’re put together; there are two slightly shinier lines for the control and test lines and at either end you can detect where the textures change again where it must be some sort of backing paper. I’ve spent a lot of time squinting at these things!

I'd do another one.

Yes I think you’re correct - that’s what it does look like. He did another one and it was negative - and released from isolation

Ah, excellent news 👏👏
