Hi ladies, I was just wondering (purely for scientific/research purposes; not because I've done it ) whether anyone has POAS on the wrong end and, if so, do you know whether this ruins the test, or can you just turn it around and pee on the correct end? Purely a question for my research ...
Pee sticks work by chromatography - as the urine wicks up, it reacts with different chemicals to form the control line and the test line.
If the absorbent material that allows the urine to soak up the stick gets wet, then no, I don't think you'd be able to use it again... if it's dry, there's nothing stopping you from turning the stick around and trying again.
Thanks, guys. I think I'm just trying to keep the faith that there might be hope ... I'm now telling myself that it's too early to test. Aaaagh, this is a cruel game.
