Evap line?

[RedPanda25]

Just wanted some eyes really and advice! Took a cb early detection test this morning and within the 3 mins it was negative. I went back a while later to throw it away and there's now a line. I'm thinking it's probably an evap line but none of my other negative tests had any line within any space of time. What do you think? First pic is within 3 mins and second is after about an hour maybe?

Test again. Get a pink dye First Response.

Thanks @TheVanguardSix apparently I can't get first response round here for love nor money! I have found another brand pink dye test though so will try that!

If it's out of the time frame then I wouldn't trust it although I would definitely be going straight out to buy a Frer to check! Hope it's good news for you.
