摘要： A test meter for use with a dual-chamber, multi-analyte test strip includes a test strip receiving module and a signal processing module. The test strip receiving module has a first electrical connector configured for contacting a first analyte contact pad of a first working electrode of the test strip; a second electrical connector configured for contacting a second analyte contact pad of a second working electrode of the test strip, a third electrical connector configured for contacting a first counter/reference contact pad of a first counter/reference electrode layer of the test strip, and a fourth electrical connector configured for contacting a second counter/reference contact pad of a second counter/reference electrode layer of the test strip. The signal processing module is configured to receive a first signal via the first electrical connector and the third electrical connector and employ the first signal for the determination of a first analyte (such as glucose) in a bodily fluid sample (for example, whole blood sample) applied to the dual-chamber, multi-analyte test strip. Moreover, the signal processing module is also configured to receive a second signal via the second electrical connector and fourth electrical connector and employ the second signal for the determination of a second analyte (e.g., a ketone analyte) in the bodily fluid sample applied to the dual-chamber, multi-analyte test strip. Furthermore, the third and fourth electrical contacts provide contact in an opposing manner.

摘要： A state, particularly a disease state, associated with the production of volatiles is detected by passing a sample containing the volatiles to a single sensor. This may be a semiconductor gas sensor element or a surface acoustic wave device. This provides an output signal, e.g. in the form of a tailing peak. A plurality of characteristics of the signal (e.g. peak height and maximum positive gradient) are measured to characterise the sample and hence the underlying state. For example we can discriminate between urine samples which are (a) infected with proteus, (b) infected with E. coli or (c) uninfected.

摘要： Liquid, particularly leaked oil or other hydrophobic liquid, is detected by a sensor. This preferably has a hydrophobic membrane (G) that takes up the oil selectively, a radiation source (A) that beams radiation at an interface between the membrane (G) and a window (F), and a radiation detector (H) that receives radiation resulting from interaction (such as reflection, scattering or fluorescence) of the input radiation with the liquid-containing membrane (G). The detector may employ a spectrofluorimeter (H) whose output can be used to characterise the liquid.

摘要： A method for the determination of an analyte in a bodily fluid sample includes transferring a bodily fluid sample (such as a whole blood sample) to a sample chamber of an analytical test strip. The analytical test strip to which the bodily fluid sample is transferred has a substrate layer, an electroluminescent module disposed on the substrate layer and in optical communication with the sample chamber, and a fluorophore-containing photometric enzymatic reagent disposed within the sample chamber. In addition, the electroluminescent module is configured to emit light that facilitates a fluorescent chemical reaction sequence involving the fluorophore-containing photometric enzymatic reagent and the analyte. The method also includes exposing the fluorophore-containing photometric enzymatic reagent to the bodily fluid sample and to light emitted from the electroluminescent module such that photons are emitted from the fluorophore-containing photometric enzymatic reagent via a fluorescent chemical reaction sequence. Moreover, the method includes detecting the photons with a photodetector.
