Patent number: 5300779Abstract: Novel methods and devices are provided involving at least one chamber, at least one capillary, and at least one reagent involved in a system providing for a detectable signal. As appropriate, the devices provide for measuring a sample, mixing the sample with reagents, defining a flow path, and reading the result. Of particular interest is the use of combinations of specific binding pair members which result in agglutination information, where the resulting agglutination particles may provide for changes in flow rate, light patterns of a flowing medium, or light absorption or scattering. A fabrication technique particularly suited for forming internal chambers in plastic devices is also described along with various control devices for use with the basic device.Type: GrantFiled: August 18, 1992Date of Patent: April 5, 1994Assignee: Biotrack, Inc.Inventors: Robert S. Hillman, Michael E. Cobb, Jimmy D. Allen, Ian Gibbons, Vladimir E. Ostoich, Laura J. Winfrey

Patent number: 5039617Abstract: Methods and devices are provided for carrying out activated partial thromboplastin time (APTT) analysis on a whole blood sample to which no anticoagulant has been added by applying the sample to a capillary track contained in a housing, wherein the capillary track comprises sample entry and venting ports, at least one capillary track connecting the entry and venting ports, and reagents capable of initiating an APTT analysis, wherein clotting time is measured by the cessation of blood flow in the capillary track.Type: GrantFiled: April 20, 1989Date of Patent: August 13, 1991Assignee: Biotrack, Inc.Inventors: Katheryne M. McDonald, Laura J. Winfrey, Michael M. Gorin, James L. Hill, Po C. Hsu

Patent number: 4731330Abstract: A whole blood control sample and a method of preparing the sample are disclosed. The method comprises collecting a whole blood sample from one or more donor, separating each sample into red blood cells and plasma, fixing the red blood cells, mixing the fixed red blood cells with plasma from the same or a different donor to produce a suspension, quick-freezing the suspension before the red blood cells can settle, and lyophilizing the frozen suspension. The control sample therefore comprises a lyophilized mixture of fixed red blood cells and plasma solids.Type: GrantFiled: July 1, 1986Date of Patent: March 15, 1988Assignee: Biotrack, Inc.Inventors: James L. Hill, Laura J. Winfrey
