Abstract
An auto-calibration system for diagnostic test strips is described for presenting data individually carried on each test strip readable by a diagnostic meter. The carried data may include an embedded code relating to data particular to that individual strip. The data is presented so at to be read by a meter associated with the diagnostic test strip in order to avoid manually inputting the information.
