ABSTRACT:
For measuring an analyte in a liquid, a test strip and apparatus each have an asymmetry. The asymmetries combine to permit a test strip to be inserted into the apparatus when it is correctly aligned but prevent the test strip from being fully inserted if it is wrong side up. The apparatus also detects whether or not the strip has been fully inserted.
