An exhaled breath condensate collection device comprising: a condensation chamber having an inlet and an outlet and arranged such that breath exhaled from the lungs of a user flows through the condensation chamber from the inlet to the outlet; at least one cooling element (16, 16a, 16b); and a frame supporting the condensation chamber, wherein, in a first configuration, the at least one cooling element (16, 16a, 16b) is operable to cool the condensation chamber so as to promote the formation of breath condensate in the condensation chamber, and wherein, in a second configuration, the cooling element (16, 16a, 16b) is displaced from the condensation chamber so as to encourage condensate to flow into a collection region in fluid communication with the condensation chamber, and wherein, in the second configuration, the frame serves as a stand for the condensation chamber, and supports the condensation chamber in an orientation such that gravity assists the flow of condensate from the condensation chamber into the collection region, characterised in that the frame supports the at least one cooling element and that the frame is moveable between the first configuration and the second configuration. a condensation chamber having an inlet and an outlet and arranged such that breath exhaled from the lungs of a user flows through the condensation chamber from the inlet to the outlet; at least one cooling element (16, 16a, 16b); and a frame supporting the condensation chamber, wherein, in a first configuration, the at least one cooling element (16, 16a, 16b) is operable to cool the condensation chamber so as to promote the formation of breath condensate in the condensation chamber, and wherein, in a second configuration, the cooling element (16, 16a, 16b) is displaced from the condensation chamber so as to encourage condensate to flow into a collection region in fluid communication with the condensation chamber, and wherein, in the second configuration, the frame serves as a stand for the condensation chamber, and supports the condensation chamber in an orientation such that gravity assists the flow of condensate from the condensation chamber into the collection region, characterised in that the frame supports the at least one cooling element and that the frame is moveable between the first configuration and the second configuration. wherein, in a first configuration, the at least one cooling element (16, 16a, 16b) is operable to cool the condensation chamber so as to promote the formation of breath condensate in the condensation chamber, and wherein, in a second configuration, the cooling element (16, 16a, 16b) is displaced from the condensation chamber so as to encourage condensate to flow into a collection region in fluid communication with the condensation chamber, and wherein, in the second configuration, the frame serves as a stand for the condensation chamber, and supports the condensation chamber in an orientation such that gravity assists the flow of condensate from the condensation chamber into the collection region, characterised in that the frame supports the at least one cooling element and that the frame is moveable between the first configuration and the second configuration.
