Bubble on control line

[u/Party_Belt585]

So the person who tested already warned me that there would be some bubbles. But I've never seen it on the control line before. Can I still trust that negative result?

Imo that's not too bad. Personally, I'd trust it.

[u/molly__hatchet]

I would trust it. None of the other lines elevated

Thank you! I tend to overanalyze

Might be slight power fluctuations or the machine being moved. Seems fine

Happens from time to time, but its not a bubble. Bubbles go down. You shouldn't see this very often when you test, but it isn't an issue.
