1. A conductivity measurement system comprising:

  • a test strip having a body, a sample container, a reference chamber, and a plurality of electrodes; and

    a measurement component coupled to the electrodes and configured to obtain a plurality of conductance measurements, wherein;

    the sample container and the reference chamber are separated by a coincident membrane, the coincident membrane having two opposed sides, one side in contact with the sample container and the other side in contact with the reference chamber, andthe measurement component is coupled to the sample container, the reference chamber, and the electrodes, and configured to;

    based on the plurality of conductance measurements, provide a determination that a temperature of the sample container and a temperature of the reference chamber are substantially the same and,based on the determination, derive a corrected amount or concentration of an analyte in a sample situated in the sample chamber.
