Additive: anticoagulant SPS (Sodium Polyanetholsulfonate) & ACD (acid citrate dextrose) What additive does: Prevents the blood from clotting and stabilizes bacterial growth.
Also, what is the purpose of sodium Polyanethole sulfonate?
Sodium polyanethole sulfonate (SPS; trade name, Liquoid) is a constituent in culture media used to grow bacteria from blood samples from patients suspected of bacteremia. SPS prevents the killing of bacteria by innate cellular and humoral factors.
Columbia Broth is particularly recommended for blood culture because of its ability to grow a wide range of microorganisms. Columbia Broth with Increased Cystein, Hemin and Menadione provide improved recovery of anaerobic microorganisms from blood specimens.
