  • Publication number: 20200407677
    Abstract: A system and method with increased sensitivity to microorganism growth. The system includes signal processing electronic circuit connected to a consumable or vessel through two or more electrodes that fully penetrate the vessel and are in contact with the fluid contents. The electronic circuit is configured to detect a component of the total impedance of the sample, specifically the “out-of-phase” or imaginary reactance component, which has a sensitive response to organism growth in a frequency-dependent manner. The system detects changes in both the composition of charged molecules in the liquid matrix and the number of microorganisms based on monitoring the sample for change in this parameter. This results in a 5-70% reduction in time-to-detection (TTD). The system and method detect organisms in a plurality of vessel shapes, volumes, and matrix (or media) formats. The electrodes are fully immersed in a continuous body of liquid sample.
