ABSTRACT:
A device for processing fluids includes a filter to capture a cell sample. The filter has a physical barrier to isolate the cell sample on the filter. Growth detection circuitry is associated with the filter. The growth detection circuitry identifies, through electrical measurements, a cell growth rate and hence the presence of live cells associated with the cell sample.
