Hereof, what is an SPS tube?
Where are SPS (sodium polyanethol sulfonate) tubes used? A. SPS tubes are used for blood culture specimen collection in microbiology. Eight gentle tube inversions will prevent the blood from clotting. The blood can remain in the SPS tube for two to four hours before it has to be transferred to a blood culture bottle.
Likewise, what is SPS in phlebotomy? Sodium polyanethole sulfonate (SPS) is the most common anticoagulant used in commercial blood culture bottles. SPS has been shown to function as an anticoagulant (4) and as an inhibitor of humoral and cellular elements that might interfere with bacterial growth.
Moreover, why is SPS used in blood cultures?
Sodium polyanetholesulfonate (SPS), an anticoagulant which inhibits the antimicrobial systems of blood, is used widely in blood culture media. The addition of SPS to experimental blood cultures inoculated with small numbers of a variety of organisms caused a striking increase in recovery of these organisms.
