Patent ID: 8551418

Claim:
A diagnostic system for analyzing a concentration of an analyte in a fluid sample, the diagnostic system comprising: a test element including at least one reagent configured to cause a reaction upon contact with the analyte in the fluid sample; and a meter including: an elongated housing; an optical read-head at a first location, the optical read-head being configured to produce a signal indicative of the reaction between the analyte and the at least one reagent; and a repositioning device configured to move the test element, the repositioning device rotating about an axis to move the test element between a first position, whereat the at least one reagent is located at a second location distal from the first location of the optical read-head, and a second position, whereat the at least one reagent is located at a third location adjacent the first location of the optical read-head, the rotational axis of the repositioning device being aligned on a common plane with the first location of the optical read-head and the third location of the at least one reagent when the test element is in the second position, wherein the rotational axis of the repositioning device and the second location of the at least one reagent are aligned along a common longitudinal plane of the housing.
