Dye running on lateral flow

[Dyerun]

Does anyone know why this would happen? 2 tests from same batch used on different people and one the dye has run so the back ground is pink? There's possibly a 2nd line but hard to tell

Hope this will attach

We had a negative within the time frame and then I left it out and it did this?

When this happens on pregnancy tests it's usually because you've flooded the test. So I'm guessing too many drops in the sample window.

Moved rather than kept really flat? More than 2 drops squeezed onto the test?
I would get them to do another one.

This happened within the 30 minutes of doing it

When i used a nasal only LFT on throat and nose (didn't realise it was nasal only), they did this.

Also, using more than the 4 drops has caused the ink to run.

In our cases these were negative, despite the whole window going pink.

I'm going to try and do another but it's on a 3 year old so not the easiest thing! Other one is mine and I did both tests in the same way. I've never seen this before

And DC does have a cold and vomiting

Its happened to me a couple of times. I did take a pcr to clarify one (negative)

This nasal only and I used 3 drops. Going to try and repeat, just feel sorry for DC

Follow the instructions - the old ones were 2 drops, our recent ones are 4 drops.

That happens on mine sometimes. I’ve never thought anything of it.

If your DC has symptoms they need a PCR.

The retest was negative 😊 I was following the instructions and I only questioned it as it looked like there was a second line but hard to tell because of the dye run. Thanks for the replies everyone

It’s important to do a PCR as the symptoms you’ve described sound like covid
My friends daughter tested negative on three LF’s and positive on the PCR

I've ordered a home PCR just to be on the safe side, it's arriving today. Very quick service!

I had a similar thing happen to me last week. My pcr was negative. Not sure why it did that as I didn’t do anything differently to normal!

@Amaretto21
I definitely would have said the 2nd one looks positive. Glad your PCR came back negative!
