With respect to pericardial, pleural, synovial, and peritoneal fluids, the inoculation of blood cul-ture broth bottles at the bedside or in the laboratory may be beneficial. An additional specimen should be submitted to the laboratory for a Gram stain. The specimen in the blood culture bottle is processed as a blood culture, facilitating the recovery of small numbers of organisms and di-luting out the effects of antibiotics. Citrate or sodium polyanethol sulfonate (SPS) may be used as an anticoagulant.
