Blood Test using HPT

Ok... Does anyone else think that doing these blood tests and making yourself bleed is kinda stupid?
If the hpt were designed to read your blood, they would say so right?
I just don't see why?
If you don't get a BFP using pee, either wait and test again in couple days or go to the doctors for bloodwork.
Don't start pricking yourself for the sake of a desperate need to get a Faint Line...
