Sample collection and testing system

A sample testing device (10) is disclosed which includes a liquid chamber, a reagent chamber (38), a sample measurement chamber for retaining sample to be analyzed, a sample collection member (12) used to collect sample from an environment to be analyzed, and a displacement member (44). The sample testing (10) device is configured such that displacement of the displacement member (44) mixes liquid from the liquid chamber with reagent from the reagent chamber (38), and propels the liquid and reagent into contact with the sample collection member (12) , resulting in the sample leeching from the sample collection member (12). The displacement of the displacement member drives the liquid and reagent into the sample measurement chamber. A photon detector (70) is provided to detect photons from the sample held in the sample measurement chamber, and a communications port (108) for connecting the sample testing device (10) to an additional measurement device (107), capable of measuring a parameter in addition to that supplied by the photon detector (70), is provided.
