ABSTRACT:
A cuvette based testing device for use in testing or otherwise analyzing a fluid sample. A cuvette is provided that defines at least one conduit, wherein the fluid sample is introduced into the various conduits. Reagents are disposed within the conduits that are intended to be mixed with the fluid sample. The fluid sample is drawn into the conduits by the force of a pneumatic pump. As the fluid sample contacts the various reagents, the reagents mix with the sample. Mixing is further conducted by moving the fluid sample back and forth across an obstruction in the conduit. The obstruction causes turbulent flow in the fluid sample, thereby mixing the sample with any reagent also present. The conduit is preferably transparent. The fluid sample is brought to a point in the cuvette where it is disposed below a detector. The detector is used to measure a characteristic of the fluid sample such as optical density, nephelometry, fluorescence, chemical luminescence, photoemittions or the like. By knowing the reagents mixed with the sample and measuring one or more characteristics of the fluid sample, the sample can be accurately analyzed for many differing tests.
