Abstract
An apparatus and method for detecting metabolic activity in a medium which includes an electrical circuit suitable for passing electrical current through a medium which contains a suspected metabolic agent. The circuit includes means for generating a reference voltage. When metabolic activity occurs in the medium the voltage drop thereacross changes. To balance the changing voltage developed across the medium with the generated reference voltage, an adjustment of current has to be performed. By monitoring such adjustments, made electrically and automatically, there is a correlation made between those adjustments and the metabolic activity in the medium. Use of this apparatus and method allows large quantities of sample media to be tested for detection of metabolic activity rapidly, accurately and reliably.
