No, wait!

The test dried a bit darker. I'm upgrading it to inconclusive.

You still need POAS squinto-vision, but if you do squint really hard, click your heels three times and hope for the best, there's the merest hint of a faint darkening where a line might be imagined to be.

So, therefore the upgrade: inconclusive.

It would still be negative to a normal person, so don't go getting all excited on me.
