i am a MA student at Milan and need help. My teacher says if we can draw blood from him, we get extra credit points. He has a lot of scar tissue on both antecubital spaces. No one has been able to get blood from him for years. Do you have any advice on what i can do to draw his blood. We can use vacuum container or butterfly syringe draw. N o one can see his veins, feel anything, or tell where scar tissue starts and ends. Please help!
