Sodium polyanethol sulfonate (SPS) is a polyanionic compound. It is a common additive to blood culture media used to grow bacteria in patients with bacteremia. SPS is as an anticoagulant and inhibitor of many human antimicrobial immune functions, improving recovery of microorganisms from blood specimens. It is a standard component of clinical blood culture systems, where it prevents microbial killing by both humoral and cellular immune mechanisms present in the blood.
