ABSTRACT:
A method and apparatus are disclosed which provide for improved rapid quantitative analysis of a blood sample for the presence of microbial pathogens. The blood sample is lysed and deposited on a high density, water immiscible, hydrophobic, nontoxic, liquid cushioning agent and subjected to centrifugation. Microbial pathogens contained in the lysed blood sample will collect in a layer adjacent the interface of the cushioning agent and the blood sample residue and, in this concentrated form, can easily be separated from the residual portion of the blood sample for culturing and quantitative counting.
