INSTRUMENT FOR DETERMINING CONCENTRATION OF MULTIPLE ANALYTES IN A FLUID SAMPLE

摘要

An instrument [20] for reading test strips [8]to determine concentrations of analytes from body fluid samples that are deposited onto the test strips [48] The instrument includes a novel modular optical block [36]that can be replaced without requiring replacement of the entire instrument [20]. 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 [48] 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.
