How to fill a vial of blood?
well, i would assume the arm, that is where the veins are most visible… but my suggestion would be to call the hospital and ask if they would draw the blood for you and then help you, just because you don’t want to get air in your veins, poke the wrong spot, it would just be much easier under the supervision of a trained professional… i’m sure at most places this isn’t the first time they have been asked… hope this helps 🙂 and if you are planning on doing it at home, i would get a needle and poke your finger and do it slow, just to make sure you don’t hurt yourself or your boyfriend too bad….
