1. An apparatus comprising:
- a test element operable to receive a sample and to provide an indication of an analyte of the sample to a meter, the test element comprising a substrate and an optically readable pattern provided on the substrate and encoding information relating to the test element, the substrate having an optical transmittance relative to a light source, the optically readable pattern comprising one or more opaque marked portions and one or more unmarked portions, the optically readable pattern being readable under stationary transillumination by the light source as a shadow image projected onto a sensor.

22. A method comprising:
-
providing a meter comprising a light source and an optical sensor; providing a test element comprising a substrate, a matrix pattern provided on the substrate, and an optical pathway consisting essentially of the substrate and the matrix pattern, the optical pathway comprising one or more regions having optical transmittance relative to the light source and one or more regions being substantially opaque relative to the light source; transferring information encoded by the matrix pattern to the meter by directing light from the light source to the optical pathway and detecting light emitted from the optical pathway with the detector; and testing a sample for an analyte using the test element, the meter, and the transferred information. - View Dependent Claims (23, 24, 25, 26, 27)
