1. A luminescence detection device for quantiatively detecting an analyte in a liquid sample, which device comprises(1) an opaque reaction compartment having, along a primary axis, opposite end portions, a first of which is for introduction of fluid reagents and sample into the compartment and the other of which forms a light transmission aperture of predetermined size, the compartment being suitable to hold a composition which luminesces in response to contact with analyte-containing sample;

  • (2) closure means in said first end portion for admitting a cannula, whereby fluid is introduced into said compartment, and for closing the reaction compartment;

    (3) a photoresponsive imaging layer;

    (4) means for associating the photoresponsive imaging layer and the reaction compartment such that the photoresponsive imaging layer is positioned at a predetermined distance from the end portion forming the aperture so as to be exposed to light emanating therefrom; and

    (5) means for blocking the photoresponsive imaging layer from exposure to ambient light.
