1. A method for determining glucose concentration, the method comprising:

  • applying an unmetered whole blood sample to a reagent test strip for use in an apparatus for determining the blood glucose concentration of a sample of whole blood, the apparatus including optical means for detecting intensity of light reflected from a reading surface portion of the reagent test strip, the reagent test strip comprising;

    a sample receiving surface portion for receiving an unmeasured whole blood sample; and

    a reading surface portion, other than the sample receiving surface portion, from which reflectance is read by the apparatus;

    allowing the sample to migrate to the reading surface portion; and

    monitoring the reflectance of the reading surface portion using the optical means of the apparatus;

    wherein the applying of the unmetered whole blood sample occurs while the reagent test strip is in use in the apparatus.
