I took a test about a week ago, there was an instant line before the control line but it dried with like a dye run so I chucked it and put down to a faulty test.
Emptied bin today and saw the test and what an evap!
No real reason for the post just shocked as in 2 years nearly I’ve never seen an evap quite like it! The one I did the day before this test had no line at all!
