Diagnostic testing apparatus for evaluating entrainable substances (e.g. for determining allergen activity in house dust), comprising a housing for collection and testing of entrainable substances, the housing having: an inlet; an outlet; a filter disposed between the inlet and the outlet which is configured to capture substances entrained in air flowing from the inlet to the outlet; a reservoir for storing fluid for use in evaluating substances captured on the filter; and means for releasing stored fluid from the reservoir onto the filter.

Assay device for evaluating entrainable substances

An assay device comprises a tube, a removable top part and a bottom part, wherein an elongate member with a swab at its distal end is mounted on the top part, the top part includes a compartment containing liquid and partly defined by a first frangible membrane that can be ruptured to release the liquid into the tube, and the bottom part contains a reagent and is partly defined by a second frangible membrane that can be ruptured on movement of the bottom part relative to the tube. Reaction occurring in the bottom part can be observed through a window. This reaction may be of the type involving amplification of say, ATP, e.g. by providing AMP, glucose-6-phosphate (G6P), adenylate kinase, glucokinase and reagents that convert glucose (G) to give a color, whereby the following reactions occur
