1. An apparatus for testing the integrity of closed vials, each closed vial being adapted to contain at least one test sensor for testing for diabetes, the apparatus comprising;

  • at least one sealable test chamber adapted to receive a closed vial, said sealable test chamber consisting of at least two parts moveable relative to one-another;

    a pick-up and placement station for placing a closed vial into a sealable test chamber;

    a pressure decay test station for moving the at least two parts of said sealable test chamber between an open position allowing the introduction and later removal of a closed vial, and a closed position providing an air-tight seal there between;

    the pressure decay test station comprising a mechanism for introducing gas into said test chamber for a first predetermined time period at a pressure sufficient to exceed a first threshold pressure for a closed vial of sound integrity, and a measurement mechanism for measuring the pressure of the gas within said sealable test chamber surrounding said closed vial at a first time point following the end of the first predetermined period of time;

    wherein a signal indicative of an alarm is generated if the pressure of gas measured within said sealable test chamber surrounding said closed vial at said first time point lies below a target pressure thereby indicating that the integrity of the closed vial may be compromised.
