evaporation line Or faint line

[Kenziefinnegan]

Is this a evaporation line or a faint positive

I wouldn’t read it as positive I’m afraid. It’s a bit grey and there’s a blank bit on the bottom. There also seems to be a lot of wet under the cap, so I’m assuming you tested mid stream rather than collecting in a cup and dipping the test in? It may have flooded the test which can cause lines.
I think you need to retest using FMU, but dip in a sample collected in a cup.
