Flowflex lateral flow test with pink background

[EMRICHES03]

Hello, I hope that this finds you all well,
Has anybody had any experience with a pink background on a child’s lateral flow test?

Have you got a picture?
They quite often leave a "smear" of dye running up the test strip. You can still get a positive line on them.
If in doubt, you could repeat the test?

I thought that but only when my little one has been very snotty

Thank you for your responses….I can’t work out how to upload a photo off my phone🤦‍♀️
There is a strong pink line on the C but there is a faint pink background to the rest of the test.

I have tested twice now with the same outcome.
