  • Publication number: 20210382044
    Abstract: A method for measuring the presence of calprotectin (S100A8/A) heterodimer in a biological sample using a particle-enhanced turbidimetric immunoassay (PETIA) based on monoclonal antibodies. The method can be adapted on automated standard analyzers and provides a reliable clinical measurement of calprotectin in faecal samples and extracts. The method is comparable to commerical two-site sandwich ELISA. The disclosed method counters spontaneous agglutination caused by calcium ions and low-molecular weight calcium-binding S100 proteins as observed with conventional PETIAs. The method can be used for measuring the presence of human calprotectin in stool, urine, serum, plasma, synovial liquid and other body liquids. Metrological traceability and high commutability with conventional immunoassays (ELISA) has been shown despite of different measurement principles used.

  • Publication number: 20210172945
    Abstract: An analyte testing system for quantifying the presence of an analyte in a speciment by lateral flow chromatography. The system comprises a test cassette (10) with a lateral flow chromatography and a mobile hand-held processor device (16) comprising a digital camera (16a), a source of light (16b) and a processor (16c), which software and hardware (16c) are configured to determine automatically the distance between camera and object and the measures of light in the region of interest of the lateral flow chromatography prior any retrieval of image data for further analysis and quantification of the visual signals.
