Abstract: Embodiments of the present invention relate to multiple coagulation test cartridges and methods of using such cartridges. In one embodiment the cartridge is a disposable single-use cartridge for use in evaluating blood clotting. The cartridge includes multiple containers, such as tubes, each of which includes one or more coagulation affecting substances. The containers can be pre-filled with substances in amounts suitable for use with a single patient's blood sample. The cartridge may include one or more containers, each of which has multiple sections, or volumes, each section storing a different coagulation affecting substance. In another embodiment the cartridge is used in a method for determining at least one appropriate coagulation affecting substance for modifying a patient's coagulation status using a multiple coagulation test system.
Abstract: The present invention relates to a reliable method of prediction of sepsis in humans after a trauma, wherein the level of pancreatic stone protein/regenerating protein (PSP/reg) is determined in serum, and a high level is indicative of the development of sepsis at early stages of the disease. Furthermore a method of determination of PSP/reg levels in serum is described.

Abstract: Disclosed is a test device and a method for qualitatively and/or quantitatively measuring the concentration of an analyte in a biological fluid sample. The test device includes a housing defining a sample port, a test well containing a stirrer and a conjugate, and a test strip disposed within the housing. The test well is also defined by being located between the sample port and the test strip. Fluid flows from the test well onto the test strip, which has a trapping zone which binds the analyte and allows for its detection. A control zone may also be included. The test device is generally adapted to use a sandwich assay. Also disclosed is a system comprising the test device and a signal sensing device; and a method for using the test device.

Abstract: The present invention provides a method for determining whether a subject is suffering from celiac disease by contacting a sample of bodily fluid from the subject, with an antigen formed from a hexamer of a gliadin fusion protein immobilized on a solid support. The gliadin fusion protein of the antigen includes a recombinant deamidated gliadin linked to a tag such as Glutathione-S transferase (GST) protein. The antigen is prepared by immobilizing the gliadin fusion protein on the solid support. The antigen can further include tissue Transglutaminase (tTG) cross-linked to the gliadin fusion protein. When tTG is present, the tTG and recombinant deamidated gliadin are mixed together prior to immobilization to the solid phase.

Abstract: The present disclosure relates to a process for detecting and optionally quantifying an analyte in a sample in the presence of a soluble target of the analyte. The soluble target forms a complex with the analyte and thus may interfere in determining the total analyte concentration. The process of the present invention utilizes a unique modified citrate buffer for diluting the sample containing the analyte and the soluble target which in turn helps in dissociating the analyte-soluble target complex, thereby enabling the process of the disclosure to detect and optionally quantify measure the analyte accurately.

Abstract: Disclosed herein are systems and methods for using the controlled movement of magnetic particles using controlled magnetic fields in a fluidic device containing separated fluidic regions to detect analytes in solution by immunoassay, such as an enzyme-linked immunosorbant assay (ELISA) for various medical and scientific applications. In order to achieve sequential exposure to the different chemical environments required in an immunoassay, magnetic particles are driven through fluid-containing chambers separated by air-gaps that may take the form of air bubbles or small open-air separations, for example. Externally controlled magnets coupled to actuators draw the flow of magnetic particles through air-liquid interfaces produced by microfluidic surface tension at the air-gap, washing the particles.
