A hollow, frustum-shaped disposable device is used in an apparatus for measuring the concentration of an analyte in a sample of a biological fluid. The smaller end of the frustum has a porous membrane, to which a sample of the fluid may be applied. Preferably, a reagent in the membrane reacts with the analyte to cause a color change. The device is mounted on a meter, which measures the color change and computes from the change the analyte concentration in the sample. The apparatus permits remote dosing of the device, which minimizes the likelihood of cross-contamination between the user and the meter. Devices can be mounted on the meter and released from the meter without touching them, to further protect against contamination. <IMAGE> |
