Abstract: Devices and methods for non-invasively measuring at least one parameter of a sample, such as the presence of a disease condition, progression of a disease state, presence of an analyte, or concentration of an analyte, in a biological sample, such as, for example, a body part. In these devices and methods, temperature is controlled and is varied between preset boundaries. The methods and devices measure light that is reflected, scattered, absorbed, or emitted by the sample from an average sampling depth, dav, that is confined within a region in the sample wherein temperature is controlled. According to the method of this invention, the sampling depth dav, in human tissue is modified by changing the temperature of the tissue. The sampling depth increases as the temperature is lowered below the body core temperature and decreases when the temperature is raised within or above the body core temperature. Changing the temperature at the measurement site changes the light penetration depth in tissue and hence dav. Change in light penetration in tissue as a function of temperature can be used to estimate the presence of a disease condition, progression of a disease state, presence of an analyte, or concentration of an analyte in a biological sample. According to the method of this invention, an optical measurement is performed on a biological sample at a first temperature. Then, when the optical measurement is repeated at a second temperature, light will penetrate into the biological sample to a depth that is different from the depth to which light penetrates at the first temperature by from about 5% to about 20%.

Abstract: A device and method for permitting the separation of plasma or serum from whole blood. The device comprises a matrix of hydrophilic sintered porous material to which at least one red blood cell agglutinating agent has been applied. According to a first method of using the device, a sample of whole blood is applied to a first end of the matrix and the red blood cells within the sample come in contact with the agglutinating agents present in the matrix. The blood cells agglutinate, and are entrapped in the interstices of the matrix, while substantially blood-cell-free serum or plasma accumulates near the outlet of the device. A filter means in liquid receiving relationship with the matrix functions to wick the serum of plasma from the matrix.According to an alternative aspect of the invention, a filter means in liquid receiving relationship with the outlet of the matrix functions to retain any blood cells which pass through the matrix as the filter means wicks the plasma or serum from the matrix. Additional agglutinating agents may be incorporated within the filter means to facilitate retention of blood cells which pass through the matrix.Another aspect of the present invention involves a device for the measurement of a serum or plasma sample, utilizing a matrix of sintered porous material, such as sintered glass, sintered steel, sintered ceramics, sintered plastics, and equivalents thereof. The matrix is characterized by a reproducible fluid uptake capacity proportional to the fixed dimensions of said matrix, a minimal reactivity with plasma or serum components, and a hydrophilic internal surface which enables the matrix to collect and retain a predetermined volume of sample for analysis.

Abstract: A method for determining the concentration of an analyte in a biological sample comprising the steps of: (1) providing an optical measuring instrument that comprises at least one thermally controllable optical measuring element that comes into contact with the surface of the biological sample; (2) applying an inert, thermally conductive, optically transparent coupling agent to the at least one optical measuring element or to the surface of the biological sample or both so that the coupling agent will be disposed at the interface of the surface of the biological sample and the at least one optical measuring element; (3) measuring optical properties of the biological sample by means of the optical measuring instrument; and (4) correlating the optical properties of the biological sample with the concentration of the analyte in the biological sample. A coupling agent suitable for this invention must have several properties to enable it to help decrease measurement variation, especially drift. One of the most important properties is sufficiently high optical stability that the optical properties of the coupling agent do not change even during prolonged experiments, such as oral glucose tolerance tests. Secondly, the coupling agent should have sufficiently high thermal conductivity to allow fast, efficient heat transfer between the optical probe and the biological sample. Third, the coupling agent should have sufficiently high viscosity to prevent it from migrating from the measurement area. Yet, it should also have sufficiently low viscosity to allow sufficient contact between the optical probe and the biological sample and to permeate into any small pockets between the probe and the biological sample that would otherwise be filled with the air. Fourth, the coupling agent should be inert. Material from the coupling agent should not diffuse into the biological sample and material from the biological sample should not diffuse into the coupling agent.
