Publication number: 20220003788Abstract: A method of determining a level of interference with a photometric in-vitro diagnostic assay and an in-vitro diagnostic analyzer for carrying out the method are described. The method comprises treating an aliquot of a sample with at least one reagent to obtain a sample/reagent mixture and subjecting the sample/reagent mixture to a photometric measurement in order to obtain a result of the in-vitro diagnostic assay, and during the same photometric measurement determining a preliminary level of interference by semi-quantitatively determining one or more interfering substances in the same sample/reaction mixture. The method further comprises triggering a separate photometric measurement of another aliquot of the same sample either undiluted or diluted with a liquid other than a reagent in order to determine an effective level of interference by quantitatively determining the one or more interfering substances, only upon determining a preliminary level of interference above a predetermined threshold.Type: ApplicationFiled: June 22, 2021Publication date: January 6, 2022Applicant: Roche Diagnostics Operations, Inc.Inventors: Jean-Pierre Bolliger, Rik Harbers, Rolf Knobel

Patent number: 11150256Abstract: A reagent management system is disclosed comprising a reagent container section for receiving reagent containers and a reagent reconstitution device for reconstituting dry, or lyophilized, reagents or concentrated reagents in reagent containers in order to carry out in-vitro diagnostic tests with the reconstituted reagents. A controller is programmed to instruct the reagent reconstitution device to automatically reconstitute an initial volume of a selected reagent type in reagent containers. The initial volume is calculated based on an open container stability time (OCS) of the reconstituted reagent type for each reagent container and on a number of tests to be carried out within the OCS of the reconstituted reagent type. A reagent container for use by the reagent management system and methods of automatically reconstituting a dry, or lyophilized reagent, or a concentrated liquid reagent in a reagent container to carry out an in-vitro diagnostic test with the reagent are disclosed.Type: GrantFiled: August 20, 2018Date of Patent: October 19, 2021Assignee: Roche Diagnostics Operations, Inc.Inventors: Friedrich Ackermann, Andreas Calatzis, Rik Harbers, Roland Hutter, Jean-Pierre Bolliger, Theresa Kitcoff, Patrick Sascha Labud
