Thanks for your input German1 !
RainLover71 is right!
If you give your Blood to the red Kross in Germany they will Test it with a 3rd Generation rapid Test and a PCR RNA before they give it to other people. They are taking a high respons. and if the Test would not be a excellent Test for early detection they could`t do that.
Thanks RL, I'm happy that someone cared enough to answer!
The HIV RNA by PCR is an excellent test for early detection of HIV,it is used to screen blood donations aswell because it is so sensitive.
