Hi,

I did a test yesterday and checked after 15 minutes. There was a clear control line, and absolutely no other lines, but underneath the control line there was some (what I presume was the) blood and buffer solution moving up, just underneath the control line. Is it normal to still see the solution moving up after the 15 mins?

I checked again about twenty minutes later and this had started to fade, still no other line, and then checked about two hours later (then realised obviously I shouldn’t – only been 15mins and a 1hr) and the lower half of the test trip had started to show a bit of red. I presume this is normal, but just wanted to reach out and check. As I say, no other line at all just the control line and then the red floating up in a sort of ball shape underneath.

Thanks
