  • Patent number: 9239326
    Abstract: Methods, devices, kits and compositions for detecting the presence or absence of hookworm in a fecal sample are disclosed herein. The methods, devices, kits and compositions of the present invention may be used to confirm the presence or absence of hookworm in a fecal sample from a mammal that may also be infected with one or more of roundworm, whipworm, and heartworm. Confirmation of the presence or absence of hookworm in the mammal may be made, for example, for the purpose of selecting an optimal course of treating the mammal and/or for the purpose of determining whether the mammal has been rid of the infection after treatment has been initiated.

  • Publication number: 20150362352
    Abstract: A chemical analyzer includes a slide transport mechanism having a slide track adapted to hold a plurality of reagent test slides, a sample metering device, an incubator formed as a part of the slide transport mechanism to precisely maintain the temperature of the reagent test slides, a slide ejector mechanism to remove the slides from the slide transport mechanism, a sample preparation station, which includes a centrifuge, and associated electronics and software. The slide transport mechanism holds a plurality of trapezoidally-shaped reagent test slides about its circumference, which slides are loaded onto the transport mechanism by the slide inserter mechanism. The slide transport mechanism positions the reagent test slides under the sample metering device, which device deposits a predetermined volume of sample onto each slide. The slide transport mechanism also carries the slides above a reflectometer.

  • Patent number: 9151731
    Abstract: A fluid pressure control device, including a pressurized fluid inlet, a first valve in fluid communication with the pressurized fluid inlet and controlling the flow of fluid from the pressurized fluid inlet, a first pressure measurement device detecting a fluid pressure downstream of the first valve, and a controller electrically coupled to the first valve. The first pressure measurement device causes the controller to operate the first valve such that a fluid downstream of the first valve is maintained at a substantially constant pressure.

  • Patent number: 9151769
    Abstract: An automated method for calibrating in real time a diagnostic analyzer includes the steps of receiving diagnostic results of patient samples calculated by the analyzer using pre-set parameters of the analyzer, and calculating the centroid of the analyzer's diagnostic results. The centroid of the analyzer's diagnostic results is subtracted from a centroid of diagnostic results of a field population of comparable analyzers to obtain a bias in the centroid of the analyzer's diagnostic results. The bias is compared to predetermined limits. Should the bias fall outside the predetermined limits, an optimization factor is derived and applied to the analyzer's diagnostic results to obtain optimized results from the analyzer without changing the pre-set parameters of the analyzer.

  • Patent number: 9091684
    Abstract: Method of detecting Symmetrical dimethyl arginine (SDMA) in biological samples. SDMA analogs for generating anti-SDMA antibodies having little or no cross-reactivity with asymmetrical dimethyl arginine, arginine, and monomethylarginine. The analogs have a protected or free thiol (—SH) group or hydroxyl (—OH) group that allow them to be linked to a suitable conjugation target which can be, for example, a protein containing molecule of a label. The anti-SDMA antibodies can be used in diagnostic immunoassay for the diagnosis of SDMA associated disorders and/or diseases.
