Whole blood hpt

I know I'm weird, but I read that using a few drops of blood and a few drops of water on a urine pregnancy test can make a positive show up sooner. Well, I tried it and it came up positive. I'm 5 dpo. I'm not taking this as a definite positive, but has anyone here tried it and actually been pregnant? Apparently it's a somewhat common practice in hospitals when a woman can't pee.
