I wasted the first test because I didn't do it right
I wasted the first test because I didn't do it right, which is why I bought 4, but I got 2 good tests, except don't put the plastic cover onto the paper until the blood is all dried. Otherwise it just spreads in the air pockets and ruins the entire test. Thankfully I took a photo before I put the plastic cover over it, so I ended up throwing the test out, but have an electronic copy.
