Abstract: The precision of a lateral flow assay for determining the concentration of an analyte in the plasma fraction of a sample of whole blood can be significantly improved by applying an integrated step for determining the hematocrit of the optionally diluted sample, and taking both hematocrit and dilution factor into account when calculating the concentration of the analyte. This is made possible inter alia by using a predetermined wavelength when taking an image of the sample after application to a substrate in the lateral flow assay device, and wherein said wavelength is selected based on the dilution factor used. This hematocrit measurement is advantageously integrated in lateral flow assay methods and devices for the measurement of an analyte in plasma and contributes significantly to an improved precision of such assays.

Abstract: NT-proBNP can be determined in a biological sample using at least one antibody which recognizes an epitope of NT-proBNP in both a glycosylated and non-glycosylated form of NT-proBNP. Said antibody is preferably an isolated polyclonal antibody or a mixture of monoclonal antibodies coated onto a particle, preferably coated onto said particle in a coating ratio of 6-60%, forming a layer or multiple layers of antibodies on said particle. The assay, realized in the form of a nephelometric or turbidimetric assay, can be applied to a wide range of automated clinical analyzers.

Abstract: The disclosure describes immunoassay methods for measurements of concentrations of related analytes in samples of body fluids from different mammalian species. More particularly, the disclosure describes reagents and methods that may be used for assays of a mammalian antigen across a range of different mammalian species, using immunological reagents based on non-mammalian antibodies the mammalian antigen. In addition, a calibrator or a set of calibrators are described that are assigned with concentration values for the antigen for each of the different mammalian species.

Abstract: The present invention relates to immunoassay methods for measurements of concentrations of related analytes in samples of body fluids from different mammalian species. More particularly, it provides reagents and methods that may be used for assays of a mammalian antigen across a range of different mammalian species, using immunological reagents based on non-mammalian antibodies towards said mammalian antigen. Moreover, a calibrator or a set of calibrators is provided, assigned with concentration values for the said antigen for each of the different mammalian species. The advantage of this invention is that the analytical laboratories or veterinarians may use the same reagents and method to test a plurality of different mammalian species without having to use different immunoassay reagents for different mammalian species.

Abstract: There is a demand for improved turbidimetric immunoassays for human Cystatin C in biological samples, especially in human clinical samples of body fluids. The present invention provides a turbidimetric immunoassay method and reagent set enabling measurement of human Cystatin C by turbidimetric methods, resulting in a surprisingly stronger and faster turbidimetric signal than in the present state of the art. The increased and faster signal is accomplished by the use of new reagents and compositions, and enables shorter assay times and kinetic reading with a stronger signal, improving overall assay speed and quality. Improved robustness to lipid interference and improved linearity is achieved.
