1. A system for measuring a property of a sample, comprising:

  • a diagnostic test strip for collecting the sample, the strip comprising two or more contacting pads, each contacting pad having a predefined electrical conductivity, and wherein the electrical conductivity of the two or more contacting pads form a code that represents information particular to the test strip;

    a diagnostic measuring device configured to receive the test strip, read the code particular to the test strip, and measure the sample; and

    the diagnostic measuring device further comprising a processor programmed to execute an error detection routine for detecting errors in the code comprising;

    comparing the code to a predetermined set of acceptable codes indicative of no error or acceptable level of error,wherein the predetermined set of acceptable codes is a set of potential codes reduced by excluding predetermined one or more codes having a probability of being misread by the diagnostic measuring device due to a defect associated with one or more contacting pads of the two or more contacting pads; and

    indicating an error if the code particular to the test strip is not in the predetermined set of acceptable codes.
