METHOD FOR DETECTING MICROBIAL PATHOGENS EMPLOYING A CUSHIONING AGENT Abstract of the disclosure An improved method and apparatus are described for detecting microbial pathogens within a sample fluid, such as blood, in which a confined sterile zone containing the sample fluid is centrifuged. According to the novel feature, the centrifugation is carried out in the presence of a high density, non-toxic, water immiscible, liquid cushioning agent, such as a fluorinated hydrocarbon. The apparatus includes an enclosed centrifugation receptacle sealably closed with injectable closure means, the interior of the receptacle comprising an evacuated space maintain- ed at a lower than atmospheric pressure, adjacent the dushioning agent which is capable of collecting substantially all of the microbial pathogens which pass out of sus- pension from the sample fluid without loss of microbial pathogens to interstitial spaces present in the receptacle.
