Blood Cultures 

Video length: 1 hour


Sepsis due to bacterial bloodstream infection is a medical emergency that requires prompt clinical intervention. Blood cultures can confirm the etiology of infection and help direct appropriate antimicrobial therapy. The utility of blood cultures is highly dependent on specimen collection. For this reason, medical institutions monitor several indicators of appropriate blood culture collection to ensure high-quality specimens are submitted to the diagnostic laboratory. This webinar will review proper blood culture collection techniques and demonstrate how specimen quality can impact patient care.
