Which skin antisepsis is appropriate before collecting blood cultures from an adult?

Blood cultures require an antiseptic effective against resident skin flora, and chlorhexidine gluconate applied with friction and fully dried is the standard for patients older than two months. A quick alcohol wipe alone does not reduce skin flora enough and leads to false-positive contaminated cultures. Sterile bottles do not protect against organisms carried in on the needle from unprepared skin.
