    Abstract: Methods and devices are provided involving an inlet port, at least one chamber, a channel providing access for fluids to flow through via capillary action or differential pressure, reagents, detection means and self-venting materials. The devices allow for the appropriate mixing, reacting, incubating needed to give a detectable signal which can be read. The self-venting materials allow for the 1) displacement of gases inside a track to the outside of the device and 2) oxygen movement into the track from the outside.

    Abstract: A method and apparatus for measuring the concentration of an analyte of interest, e.g. glucose, in blood non-invasively. The method and apparatus of this invention can also be adapted to allow a portion of a body part to be engorged with blood to bring about greater accuracy in optical measurements. In the method of this invention, at least two similar, but not identical, measurements are made concurrently. For example, two similar, but not identical, wavelengths of electromagnetic radiation can be used. The two wavelengths should not be overlapping to allow maximum non-identity. By making measurements concurrently, each measurement channel in the system experiences variations as they occur substantially simultaneously in all channels. By selecting one of the channels as a reference channel and by normalizing the optical measurements of the other channels to this reference channel, the variations common to all channels are eliminated. Removing these common variations from the optical measurements by normalization, such as by calculating ratios of the measurement of each of the measuring channels to that of the reference channel, will allow the actual changes of the signal for a specific analyte of interest to be measured.

    Abstract: Apparatus and method for determining at least one parameter, e.g., concentration, of at least one analyte, e.g., urea, of a biological sample, e.g., urine. A biological sample particularly suitable for the apparatus and method of this invention is urine. In general, spectroscopic measurements can be used to quantify the concentrations of one or more analytes in a biological sample. In order to obtain concentration values of certain analytes, such as hemoglobin and bilirubin, visible light absorption spectroscopy can be used. In order to obtain concentration values of other analytes, such as urea, creatinine, glucose, ketones, and protein, infrared light absorption spectroscopy can be used. The apparatus and method of this invention utilize one or more mathematical techniques to improve the accuracy of measurement of parameters of analytes in a biological sample. The invention also provides an apparatus and method for measuring the refractive index of a sample of biological fluid while making spectroscopic measurements substantially simultaneously.

    Abstract: A multiplex sensor and a method of use that provides enhanced selectivity and sensitivity. In this method, one or more parameters of the sample are measured by means of multiple spectroscopic techniques, and the interferences from physiological and spectral variables are reduced or eliminated. One embodiment of the present invention comprises a multiplex sensor and a method of use that provides enhanced selectivity and sensitivity. One or more parameters of the sample are measured by means of at least two different spectroscopic techniques, wherein the at least two different spectroscopic techniques are selected from the group consisting of: (a) infrared absorbance, (b) scattering, (c) emission, (d) polarization, and (e) photoacoutics.
