Patent number: 10422797Abstract: An electrochemiluminescence method of detecting an analyte in a liquid sample and a corresponding analysis system. An analyte in a liquid sample is detected by first providing a receptacle containing a fluid comprising protein coated magnetic microparticles to a stirring unit. Stirring of the fluid is necessary since the density of the microparticles is usually higher than the density of the buffer fluid. Thus the microparticles tend to deposit on the bottom of the receptacle leading to an aggregation of the microparticles because of weak interactions. To obtain representative measurements a homogeneous distribution of the microparticles in the buffer fluid is necessary to ensure a constant concentration of microparticles for each analysis cycle. It is further necessary to provide disaggregation of the microparticles, which is also realized by stirring the fluid. Stirring is conducted with a rotational frequency that is adapted to the amount of fluid to be stirred.Type: GrantFiled: December 14, 2015Date of Patent: September 24, 2019Assignees: ROCHE DIAGNOSTICS OPERATIONS, INC., HITACHI HIGH-TECHNOLOGIES CORPORATIONInventors: Ralf Kraus, Oliver Larbolette, Friedrich Staebler, Yoshihiro Yamashita, Yukinori Sakashita, Shinya Matsuoka, Michihiro Saito, Taku Sakazume, Katsuaki Takahashi

The overall diagnostic method, including the important communicative properties accorded both the particular surgeon and pathologist, is encompassed within this invention, as well as the specific collection specimen kit that permits the surgeon proper distinction of specific removal lymph nodes in relation to their location within the patient's body.Type: GrantFiled: April 2, 2018Date of Patent: September 24, 2019Inventor: Raymond U Osarogiagbon

Patent number: 10422804Abstract: Provided are methods for determining the amount of estrone in a sample using mass spectrometry. The methods generally involve ionizing estrone in a sample and detecting and quantifying the amount of the ion to determine the amount of estrone in the sample.Type: GrantFiled: June 7, 2017Date of Patent: September 24, 2019Assignee: Quest Diagnostics Investments IncorporatedInventors: Mildred M. Goldman, Richard E. Reitz

Patent number: 10422805Abstract: Disclosed is an invention in the field of conducting an immunoassay of 25(OH) vitamin D in blood or blood components, notably serum or plasma. The invention employs a perfluoro alkyl acid, or a salt thereof, to release 25(OH) vitamin D from vitamin D binding protein. Thereafter the binding protein comprising the 25-OH vitamin D is subjected to a competitive binding assay with a labeled vitamin D compound.Type: GrantFiled: December 27, 2011Date of Patent: September 24, 2019Assignee: FUTURE DIAGNOSTICS B.V.Inventors: Leon Maria Jacobus Wilhelmus Swinkels, Antonius Franciscus Maas, Michael Franciscus Wilhelmus Cornelis Martens

Patent number: 10422806Abstract: Methods for improving assays of biological samples are provided, including assays of small volume biological samples, such as blood samples obtained from a fingerstick. The methods include steps of selecting a baseline assay; providing a first revised assay by altering an aspect, a reagent, or a step of the baseline assay; comparing the results of the baseline assay and first revised assay; and identifying the first revised assay as an improved assay if the results of the first revised assay are similar to, are substantially the same as, or are better than, the results of the baseline assay. The methods may be iterated. Alterations include reducing sample volume; setting temperature; reducing step number and duration; altering reagent composition and number; and altering detection. Improved assays may reduce the duration, cost, or complexity of the assay, may improve assay sensitivity, accuracy, or reliability, and may provide synergistic improvements.Type: GrantFiled: July 25, 2014Date of Patent: September 24, 2019Assignee: Theranos IP Company, LLCInventors: Paul Patel, Ian Gibbons, Elizabeth A.

Patent number: 10422807Abstract: The present invention provides a sensitive and specific indirect homogeneous mobility shift assay using size exclusion chromatography to measure biologics such as vedolizumab and ustekinumab in a patient sample. The assays of the present invention are particularly advantageous for detecting the presence or level of biologics that target complex or large antigens including cell surface proteins, transmembrane proteins, heavily glycosylated proteins, and multimeric proteins, as well as antigens that cannot be purified, impure antigens, and partially or substantially purified antigens. The present invention also provides isolated soluble ?4?7 integrin heterodimers and isolated soluble IL-12p40 monomers that are suitable for use in the indirect assays described herein.Type: GrantFiled: May 23, 2017Date of Patent: September 24, 2019Assignee: PRECISION IBD, INC.Inventors: Jared Salbato, Stefan Westin, Nicholas Chi-Kwan Ling, Anjali Jain, Sharat Singh

Patent number: 10422808Abstract: A rinse mechanism rinses reaction cuvettes with first and second detergents. An R1 reagent pipetting mechanism 8 rinses the reaction cuvettes that have been rinsed by the rinse mechanism with a special detergent. A counting unit counts and stores in a storage unit a use frequency of each reaction cuvette for a specific reagent item. A determining unit determines whether the counted use frequency exceeds a predetermined threshold N1. A control unit controls the R1 reagent pipetting mechanism such that, in a case where the counted use frequency exceeds the predetermined threshold N1, the reaction cuvettes, which have exceeded the predetermined threshold N1, are soaked with the special detergent only for a period equal to or less than a value derived by multiplying a pipetting cycle time, which indicates a period when a sample is pipetted, by the total number of reaction cuvettes and a predetermined integer.Type: GrantFiled: February 27, 2018Date of Patent: September 24, 2019Assignee: Hitachi High-Technologies CorporationInventors: Hiroyuki Takayama, Kazuhiro Nakamura

Patent number: 10422809Abstract: A wristwatch includes a storing unit that stores relational data for predetermined user classifications, such as gender and body height, indicating a relationship between a traveling pitch, which is the number of steps taken by a user per predetermined amount of time, and a traveling speed which is a running speed or a walking speed. A correcting unit corrects the stored relational data based on a set of a measured traveling pitch and a measured traveling speed. A speed calculating unit calculates a traveling speed of the user from a measured traveling pitch of the user based on the stored relational data that correspond to a user classification input by the user and that has been corrected.Type: GrantFiled: August 8, 2013Date of Patent: September 24, 2019Assignees: SEIKO INSTRUMENTS INC., ASICS CORPORATIONInventors: Akira Takakura, Hiroshi Shimizu, Tomohiro Ihashi, Keisuke Tsubata, Takehiro Tagawa, Ryota Shinayama
