A test strip handling device, comprising: a housing having an external opening; an interior compartment disposed within the housing, the interior compartment having a space configured to store at least one test strip, the at least one test strip including a reagent adapted to react with an analyte in a fluid sample and to produce a reaction indicative of the concentration of the analyte in the fluid sample; and first and second rollers (218, 220) positioned adjacent one another within the housing, characterized in that the test strip handling device further comprises: an energy storage device including a third roller, a spring, and a locking mechanism, the third roller frictionally engaged with one of the first and second rollers and configured to rotate in a first direction to store potential energy by causing the spring to wind and to bias the first and second rollers to move relative to one another upon release of the stored potential energy, wherein the locking mechanism is transitionable between a locked state in which the spring is prevented from unwinding and an unlocked state in which the spring unwinds to convert the potential energy to kinetic energy; and wherein the first and second rollers are constructed and arranged to receive the at least one test strip there between and to guide the at least one test strip from the opening into the space of the interior compartment. a housing having an external opening; an interior compartment disposed within the housing, the interior compartment having a space configured to store at least one test strip, the at least one test strip including a reagent adapted to react with an analyte in a fluid sample and to produce a reaction indicative of the concentration of the analyte in the fluid sample; and first and second rollers (218, 220) positioned adjacent one another within the housing, characterized in that the test strip handling device further comprises: an energy storage device including a third roller, a spring, and a locking mechanism, the third roller frictionally engaged with one of the first and second rollers and configured to rotate in a first direction to store potential energy by causing the spring to wind and to bias the first and second rollers to move relative to one another upon release of the stored potential energy, wherein the locking mechanism is transitionable between a locked state in which the spring is prevented from unwinding and an unlocked state in which the spring unwinds to convert the potential energy to kinetic energy; and wherein the first and second rollers are constructed and arranged to receive the at least one test strip there between and to guide the at least one test strip from the opening into the space of the interior compartment. an energy storage device including a third roller, a spring, and a locking mechanism, the third roller frictionally engaged with one of the first and second rollers and configured to rotate in a first direction to store potential energy by causing the spring to wind and to bias the first and second rollers to move relative to one another upon release of the stored potential energy, wherein the locking mechanism is transitionable between a locked state in which the spring is prevented from unwinding and an unlocked state in which the spring unwinds to convert the potential energy to kinetic energy; and wherein the first and second rollers are constructed and arranged to receive the at least one test strip there between and to guide the at least one test strip from the opening into the space of the interior compartment.
