  • Patent number: 7993610
    Abstract: A spinnable rotor for a high speed centrifuge includes a housing which defines a chamber interiorly thereof for receiving a whole blood sample and for containing a predetermined amount of red blood cell absorbent gel. The housing includes an upper portion and a bottom portion, the upper portion having a port formed through the thickness thereof. The upper portion has at least a portion thereof formed from a light transmissible material. A light pipe is joined to the upper portion and light transmissively communicates with the light transmissive portion of the upper portion. The light pipe extends at least partially into the chamber and has an open, lower free end. When whole blood filling the rotor chamber contacts the lower free end of the light pipe, the red color of the blood is transmissively communicated to the upper portion of the rotor housing where it is viewable by the user of the centrifuge.

  • Publication number: 20110189651
    Abstract: A method and device for determining a feline immunodeficiency virus infection or vaccination in an animal. The method includes contacting a biological sample from a felid with various FIV polypeptides and determining the binding of antibodies in the sample to the polypeptides. The determination of whether an animal is infected with FIV or has been vaccinated against FIV can be determined by measuring the animal's immune response to an FIV env polypeptide. A device for detecting FIV antibodies is provided.

  • Publication number: 20110129864
    Abstract: Disclosed is a method for identifying lymphatic disease and disease states in mammals. The method uses a multi-angle light scatter flow cytometer to diagnose and treat mammals. The method includes collecting lymph node aspirate from a mammal; scanning the lymph node aspirate in a flow cytometer to generate a diagnostic scan; comparing the diagnostic scan to a known normal scan; identifying differences between the diagnostic scan and the known normal scan; and identifying similarities between the diagnostic scan and known disease scans to identify a cause of lymphadenopathy. Graphical representations of leukocyte identification are generated as a result of the scanning process. By using the graphs, a veterinarian or technician is able to diagnose the effectiveness or ineffectiveness of the treatment.

  • Patent number: RE42143
    Abstract: The present invention is a flow cytometry-based hematology system useful in the analysis of biological samples, particularly whole blood or blood-derived samples. The system is capable of determining at least a complete blood count (CBC), a five-part white blood cell differential, and a reticulocyte count from a whole blood sample. The system preferably uses a laser diode that emits a thin beam to illuminate cells in a flow cell and a lensless optical detection system to measure one or more of axial light loss, low-angle forward scattered light, high-angle forward scattered light, right angle scattered light, and time-of-flight measurements produced by the cells. The lensless optical detection system contains no optical components, other than photoreactive elements, and does not include any moving parts. Finally, the system uses a unique system of consumable reagent tubes that act as reaction chambers, mixing chambers, and waste chambers for the blood sample analyses.
