PRINTED MEMORY ON TEST STRIP

A system for analyzing biological fluids comprising: a test strip comprising a biosensor to sense a biological fluid and a plurality of diodes that are connected to a plurality of contacts on the test strip and that are arranged in a network representing one of a plurality of states based on whether the diodes are open circuited; and a mobile meter configured to supply excitation to a plurality of contacts on the test strip and measure response through the plurality of contacts, differentiate a plurality of voltage or current levels representing the plurality of states, and identify the one of the plurality of states represented by the network of diodes based on the measured current or voltage.
