Instrument for determining concentration of multiple analytes in a fluid sample

摘要

An instrument for reading test strips to determine concentrations of analytes from body fluid samples that are deposited onto the test strips. The instrument includes a novel modular optical block that can be replaced without requiring replacement of the entire instrument. Another feature of the invention is a novel encryption code that allows a technician during service calls to quickly identify all relevant manufacturing information for the test strips being used by the person placing the service call. Another feature of the instrument of the present invention is that it can be used in combination with a novel test strip capable of testing multiple analytes from a single sample.
