ABSTRACT OF THE DISCLOSURE A disposable assay device for assaying a sample comprises a body including a reaction chamber which contains or is adapted to receive an assay reagent sensitive to a component (e.g. a nicotine metabolite) being assayed for in the sample. A sample collector/dispenser has a sample collecting chamber closed by an elastic membrane and a downwardly projecting sampling and piercing tube, to enable a predetermined quantity of sample to be dispensed into the reaction chamber. The body and the collector/dispenser are non-detachably engageable together by engagement of rib on collector/dispenser with lip on the body. A seal seals the assembly to prevent leakage of the contents after use.
