An operational unit for locating and neutralizing pathogen cells in blood. A cassette has a plurality of thin holding chambers that are filled with blood drawn from a patient. A light source illuminates each of the holding chambers and passes light to an underlying sensor array such that the cells in the blood produce shadow images of the cells in the sensor array. A processor performs pattern recognition to identify and locate the pathogen cells by use of an image library. After the pathogen cells are located, the pump is operated to move the identified cells to a processing zone. When each identified cell reaches the processing zone, electric energy is applied to destroy the identified pathogen cells. A pump refills the cassette holding chambers, returns the neutralized-pathogen blood to the patient, and the process is repeated for a treatment time period.

Analysis of cell populations for both research and clinical applications such as cell therapy is often performed on whole blood that is close to 24 hours old. The reason for this is that the analysis site is removed from the blood draw site so that blood must be shipped overnight to the analysis site. During the 24-hour shipping period, granulocytes and other blood components break down into undesirable cell debris including nucleic acids that are released into the blood. Such debris is known to interfere with immunological assays and with thawing following freezing of samples. The present invention solves this issue by removing granulocytes (and optionally other components) using an anti-CD15 molecule (or other appropriate molecule) bound to metallic magnetic particles. Following mixing, the granulocytes (or other components) are removed and prepared for shipment to the analysis site or for other reasons.
