Question

What concentration of chlorhexidine is used most commonly as skin disinfectant for blood culture specimen collection?

Answer 1

Explanation:

Like iodophors, chlorhexidine has limited activity against fungi and mycobacteria. A 2% chlorhexidine solution is preferred over 70% alcohol or povidone-iodine for skin preparation of central venous catheter sites in human patients18 and is the skin antiseptic of choice for collection of blood for blood cultures
