The present invention is a method of preventing reuse of test strips for measuring an analyte or indicator such as glucose in a physiological fluid such as blood, interstitial fluid, or urine. The present invention also relates to a method of preventing reuse of test strips incorporating an integrated lance such as a needle, blade, or other sharp or skin puncturing device. Certain types of medical devices such as, for example, glucose test strips were intended to be tested only once and then disposed. This requirement is often needed because the reagent chemistry in many test strips is not suitable for measuring glucose a second time. However, it is possible that some user will accidentally test a previously used test strip. This could potentially become a problem if the glucose meter attempts to make a glucose measurement and outputs a result. Therefore, it is desirable that a single use test strip and meter have a prescribed method for preventing a previously tested test strip from being reused.
