How common are evap lines on blue dye tests?

[Alb1]

I used a sainsburys own test this morning and it came up with a very faint line within the time limit, I opened up the test and it deff has colour in it, but I've seen a few times on here about evap lines and blue dye ones being really bad for dye run, anyone has experience of this?

I'm 9dpo so still early days I no

I saw your post on my thread about these tests alb1, I keep reading stuff about them being unreliable but not sure if it is true. I was going to wait until tomorrow to do a pink dye test but being the impatient soul that I am I used the other sainsburys one tonight (it was a 2 pack) and the result was identical to the one this morning. I'm still going to have to do a pink dye test tomorrow just to put my mind at ease.

Good luck summer I'm going to do my other blue one in the morning as well as a pink one, il be 10dpo tomorrow though so not expecting any deep lines if anything does come up

Good luck to you too. I think I am about 12 days po. I will report back late morning.

My blue dye this morning is as faint as yesterday's but I do also have a faint line on my superdrug early! Not going to get my hopes up until I've missed a period though. Hope it's good news for you

The super drug ones are supposed to be very reliable.

Pink dye test done and the line was very very faint, had to squint to see it so not sure what to think as the sainsburys one was not as faint

What brand was it summer?

Here you go. I took a picture. As you can see it is much fainter than the blue dye ones. I wish I had just got a FRER test but they didn't have them in the shop 😩

It was just a cheapie from the local chemist that said early pregnancy test. It said it can measure 25miu so I thought it would be okay

Well this is my superdrug early one which I think are 10miu. I think for the sensitivity of yours it looks good!

Apparently the sainburys ones are 15miu which would explain the fainter result from my asda one.

Okay, DH arrived home with a clear blue early detection test (yes, flipping blue dye) and insisted that 'this one is reliable cos it says recommended by doctors on the packet'. This one is definitely positive, no doubt about it. I suppose I have learned my lesson about cheap tests.

That's great news summer congratulations

Thanks Alb. I'm keeping my fingers crossed for your lines getting darker.
