Patent number: 11867708Abstract: Systems and methods for calibrating laboratory instruments. In an example, a laboratory instrument for testing patient specimens includes a testing apparatus configured to receive a cassette that includes a patient specimen or a quality control specimen. In response to determining that a quality control specimen is present, the instrument obtains a first measurement of a parameter. If the first parameter is outside an expected tolerance, the instrument ceases performing tests on all specimens, the instrument re-tests the quality control specimen to obtain a second measurement of the parameter. If the second measurement is within the expected tolerance, instrument resumes processing of the cassette. If the second measurement is outside the expected tolerance, the instrument indicates that recalibration or service is required.Type: GrantFiled: August 7, 2019Date of Patent: January 9, 2024Assignee: Beckman Coulter, Inc.Inventors: Madhuri La Barrie, Scott Lendzian, Joanna Selinsky

Patent number: 11846616Abstract: Improved systems and methods for laboratory instrument calibration. A laboratory instrument retrieves a number of sets of past quality control parameters from a data structure. Each set includes a recovered value and a timestamp. The recovered value is equal to an output value adjusted by an initial calibration factor. The laboratory instrument determines that the number of sets is greater than a threshold and that each of the past quality control parameters has a timestamp that is within a time threshold. The laboratory instrument computes an updated calibration factor such that when the updated calibration factor is applied to a representative value of the recovered values, the representative value equals the expected recovered value. The instrument updates the data structure with the calibration factor such that the calibration factor is used in subsequent testing of patient specimens.Type: GrantFiled: August 7, 2019Date of Patent: December 19, 2023Assignee: Beckman Coulter, Inc.Inventor: Carlos A.
