  • Publication number: 20240061001
    Abstract: An external calibration curve relies on external calibrators containing known concentrations of a target analyte that can deteriorate over time, leading to inaccurate results. Generating new calibration curves often requires preparing several calibrators to obtain calibration points needed for generating the calibration curves. Preparing the calibrators necessary for multi-point calibration curves requires operator preparation time and can introduce handling errors. The presently claimed and described technology provides a clinical laboratory automation system, including a fluid handling system, an analyzer component, and a mass spectrometer. The clinical laboratory automation system can provide automated calibration using one calibrator to prepare one or more calibrator dilutions used to generate a calibration curve for the quantitative measurement of a target analyte in a sample.

  • Patent number: 11879851
    Abstract: A luminometer (400) includes a light detector (630) configured to sense photons (135). The luminometer (400) includes an analog circuit (915a) configured to provide an analog signal (965) based on the photons (135) emitted from assay reactions over a time period and a counter circuit (915b) configured to provide a photon count (970) based on the photons (135) emitted from the assay reactions over the time period. The luminometer (400) includes a luminometer controller (905) configured to, in response to an analog signal value of the analog signal (965) being greater than a predetermined value, determine and report a measurement value of the photons (135) emitted from the assay reactions over the time period based on the analog signal value of the analog signal (965) and a linear function (1010). Optionally, the linear function (1010) is derived from a relationship between the analog signal (965) and the photon count (970).

  • Publication number: 20240003923
    Abstract: The presently claimed and described technology provides improved calibration and validation procedures for sample containers (e.g., cuvettes) in automated chemical analyzers. The claimed and described technology further provides methods of operating an automated analyzer that allows for the automation of calibrating and tracking the integrity of individual sample containers (e.g., cuvettes) in parallel with measuring constituent samples. These methods eliminate the need to alternate between a diagnostic mode and measurement mode when performing system maintenance, such as validating cuvette integrity, calibrating absorbance baseline, and replacing cuvettes. As such, the presently claimed and described technology can reduce downtime and improve the clinical lab productivity significantly by allowing for this system maintenance to occur simultaneously with sample analysis.

  • Publication number: 20220050121
    Abstract: Quality control tests for a diagnostic instrument can be run in an efficient manner by using a subset of the potential quality control materials to perform tests for identifying failures in the diagnostic instrument's components. Such subsets could be defined in a variety of manners, and could allow component failures to be tested relatively more frequently in a more efficient manner. Additionally, issues for particular components of diagnostic instruments may be identified based on analysis of quality control results. This identification may be part of a method that comprises receiving a plurality of quality control results wherein each quality control result from the plurality of quality control results is obtained based on performing a measurement of a corresponding quality control sample using the diagnostic instrument.
