A diagnostic device adapted to retain a fluid sample to be analyzed until it is desired to initiate the analytical test is described. The device includes a deformable material layer, a well for holding a fluid sample, a porous material and a diagnostic assay element.

Diagnostic assay device

There is described a self-developing film unit which has a photosensitive member and an image-receiving member and wherein one outermost surface of the film unit comprises a support layer carrying a layer of a releasable material and a layer of an adhesive material. After an image is formed in the film unit by photoexposure of the photosensitive element and photographic processing of the exposed photosensitive element, the support and releasable material layer can be removed and the film unit or the image-receiving element, as the case may be, adhered to a surface for viewing of the image.

Self developing-film unit

A diagnostic assay device comprising a housing assembly and an image recording material housed therein that is exposed by a luminescent read-out signal generated by a luminescent activity triggered in response to displacement of a liquid carrier assembly carrying an analyte of interest with a reservoir containing an assay solution.
