<p>A testing device for use in examining a fluid specimen for a preselected substance in the specimen including a housing having a section for receiving and examining a sample of the specimen to produce a quantitative measurement of the preselected substance therein. The housing includes a second section formed with a cell for receiving a second sample of the specimen. The device also includes a sensor for sensing and measuring a particular electrical or physical property of the second sample in the cell useful in interpreting the results of the quantitative measurement of the substance in the first-mentioned section of the housing. In the described preferred embodiment, the housing is of a plastic material for use as a disposable point-of-care unit, the fluid specimen is urine or other body fluid, the preselected substance is a biomarker, such as a thromboxane, and the sensor senses electrical conductivity to produce a concentration-normalized measurement of the biomarker.</p> |
