ABSTRACT OF THE DISCLOSURE Disclosed is a luminescence detection device for quantitatively detecting an analyte in a liquid sample, which device comprises (1) a reaction com- partment 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 transmissive aper- ture 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 com- partment; (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, pre- ferably substantially perpendicular to the primary axis of the reaction compartment, at a predetermined distance from the end portion forming the aperture so as to be exposed to light emanating therefrom; and (5) means for preventing exposure of the photorespon- sive imaging layer to ambient light.
