Abstract
A method and apparatus for analyzing a sample to determine an analyte content has a sensor for sensing the analyte positioned between a first and second transducer. The analyte or derivatives thereof are reciprocated between the first and second transducer to reciprocate at the sensor and allow instantaneous sensing of an indication of the analyte's presence at a point between the first and second transducer. Rapid analysis can be carried out in many different systems including for example where the transducers are enzyme reactors and the analytes are body metabolites.
