  • Patent number: 7591978
    Abstract: A solid-phase test device and a method for the detection of sialidase activity in a fluid sample. The test device includes a solid support provided with a pre-deposited dry form of a sialidase detecting composition. The sialidase detecting composition includes a sialidase substrate and a color-developing reagent. When the sialidase substrate is exposed to sialidase it yields an intermediate compound which reacts with the color-developing reagent to form a detectable color change.

  • Patent number: 7060453
    Abstract: A method is provided for determining the level of an analyte in the blood of an individual based on determination of the level of the same analyte in non-blood sample (e.g. urine, saliva and hair) obtained from the individual. The non-blood sample contains red blood cells and the volume of the blood in the sample together with the amount of the analyte in the sample are the basis for calculating the level of the analyte in the individual's blood. Kits for carrying out the above method are also provided.

  • Publication number: 20060105402
    Abstract: A method for the detection and/or visualization of particle agglutination in a particle suspension is provided, comprising placing a volume of the particle suspension and a volume of a solution or suspension containing an agglutinating agent at substantially the same selected location on a surface of a filter constructed so as to permit passage of individual unagglutinated particles in a direction perpendicular to the surface. A wash solution at optionally placed at substantially the same location as that of said agglutinating agent, and the surface is observed for the presence of particles. There is also provided a method for detection of agglutination reactions, such as used in blood grouping, reverse grouping and cross-matching. A device and a kit based on the invention is also claimed, which facilitates blood grouping, reverse grouping and matching in non-laboratory environment without the need for laboratory instruments.

  • Patent number: 7021122
    Abstract: A sensor device (10) and a method for measuring a viscosity of a sample of a liquid. The sensor features a chamber (12) for receiving the sample of the liquid, two electrodes (18) disposed either on the surfaces of the chamber, but possibly isolated from contacting the sample, or electrodes located externally to the chamber, and a capacitance measuring circuit (25). The sensor is used by connecting to a measurer for determining a capacitance on the electrodes, such that the capacitance directly reflects a volume occupied by the sample of the liquid. Preferably, the liquid is blood and the capacitance is used to determine the clotting time of the blood. Also preferably, a cover for the chamber is provided with at least one aperture, which more preferably is a mesh. Alternatively, an electrical property such as the amplitude of current passed through the sample is used to determine clotting time. Also preferably, the time period required for the maximum capacitance to be reached could be measured.

  • Patent number: 7004901
    Abstract: A method is provided for determining the level of an analyte in the blood of an individual by measuring the level of the analyte in an interstitial fluid or in any other non blood fluid which does not contain red blood cells and adjusting the measurement value by the concentration of at least one reference analyte.

  • Publication number: 20050109951
    Abstract: A device, system and method for portable fluorescence detection. The portable device of the present invention features a low power light, in which a wavelength range is defined as at least one wavelength of light. The light source is preferably highly energy efficient, such that a majority of the electrical power which is consumed is then converted into transmitted light. The emitted light from the excited fluorophore is then preferably detected with any low cost and low power photodetector. Although optionally a highly sensitive optical detector may be used, preferably fluorescence is detected with any light sensing device, such as a regular photodiode or a CCD (charge-coupled device) sensor for example.

  • Publication number: 20050084879
    Abstract: A method for the detection and/or visualization of particle agglutination, comprising: placing a volume of a suspension of the particles on a filter, the filter being constructed so as to permit passage of individual particles; placing a volume of a solution or suspension containing an agglutinating agent at the location of the particle suspension; optionally placing a wash solution at the location of the agglutinating agent; and observing the surface at the location for the presence of particles, such presence indicating that agglutination of the particles occurred. There is also provided a method for detection of agglutination reactions in general and hemagglutination reactions, such as used in blood grouping and cross-matching, in particular. The method is comprised of successive vertical additions of whole blood, blood grouping reagent and wash to a filter. In case of hemagglutination a colored, preferably red or reddish dot becomes visible after washing.

  • Publication number: 20040077933
    Abstract: A method and system for detecting or quantifying biologically effective radiation emitted from an activated wireless communication device such as a cellular phone or the antenna of a cellular phone. The method uses microorganismal cells producing a detectable response when exposed to biologically effective radiation. The device is placed a predetermined distance from microorganismal cells and then activated for a predetermined amount of time. At the end of the predetermined amount of time, it is determined whether the response was produced in the cells. Production of the response indicates that the device emitted biologically effective radiation.
