Abstract: Instances of the present technology may include a method for operating a hematology analyzer. The method may include passing a control material through a hematology analyzer. The control material may include a first cell population and a second cell population. The method may also include determining a first cell population volume measurement and a second cell population volume measurement. A first value of a first cell population distribution width and a second value of a second cell population distribution width may be calculated. The method may include comparing the first value to a first reference range. The method may also include comparing the second value to a second reference range. Furthermore, the method may include classifying an operational status of the hematology analyzer based on the comparison of the first value to the first reference range and based on the comparison of the second value to the second reference range.

Abstract: 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.

Abstract: A server stores a set of laboratory applications to process batches of samples. The server receives, from a first lab administrator, a selection of a subset of the laboratory applications to process the batches of samples and an admin configuration for a laboratory application in the subset. The server receives configuration(s) of batch(es) to be used for running at least a portion of the subset of laboratory applications configured according to the admin configuration. The server receives, from a first scientific device, a request to run a laboratory application form the first subset to process a batch. The server provides the laboratory application(s) that are capable of being executed using the first scientific device. The server receives, from the first scientific device, a selected laboratory application. The server transmits, to the first scientific device, a signal for executing a first part of the selected laboratory application.

Abstract: Systems and methods for characterizing immune response to infection using cellular analysis, such as a hematological cellular analyzer. In some instances, the immune response may be characterized as normal or abnormal based on one or more blood cell population parameters. In some instances, abnormal characterization may be used to identify patients with sepsis or at elevated risk of developing sepsis.

Abstract: A middleware device or software may be placed in communication with one or more testing instruments and a lab information system. As samples are collected from patients and tested with the testing instruments, test results pass through the middleware and are analyzed in context with other data, such as patient history, testing instrument history, and test results from other tests of the sample, in order to determine whether a particular result is acceptable, whether retesting is needed, whether additional sample collection or testing is needed, and whether currently ordered testing is still necessary. When the middleware determines a need for additional testing or retesting it may automatically create orders for such testing in order to reduce delays in manual review of testing results.

Abstract: The method involves drying down dye-conjugated reagents in separate locations in a reaction vessel so that the dyes don't non-specifically interact with each other during drying. This invention thus improves multiplex binding assays by eliminating erroneous results caused by dyes' being non-specifically attached to each other when dried down together.

Abstract: Assays (100) may be performed with a luminometer (400) having a chassis (405) that may include a reaction vessel chamber (610). The luminometer (400) may also include a light passage (640) that intersects the reaction vessel chamber (610). The luminometer (400) may also include a cap (415) that, when in a closed configuration, prevents light emitted by external sources from entering the reaction vessel chamber (610) and from entering the light passage (640). The cap (415) may provide access to the reaction vessel chamber (610) when in an open configuration. The luminometer (400) may also include a calibration light source (460) optically coupled to one end of the light passage (640) and a light detector (630) optically coupled to another end of the light passage (640). The light detector (630) may include a sensing element for receiving light from the light passage (640).

Abstract: An optimized testing method is used to determine minimum inhibitory concentration (MIC) of a particular antimicrobic for use with a particular microbe. The testing method includes iteratively imaging the microbes mixed with various concentrations of the antimicrobic. The images are thereafter processed to determine one or more of the amount/count of the microbes in each image, the total area occupied by the microbes in each image, and the ratio between the area occupied by the microbes and the count of the microbes. Once a sufficient amount of data is collected, the MIC is determined based on one or more of the count, area, and ratio datasets.

Abstract: This invention provides methods to evaluate therapeutic efficacy of therapeutic monoclonal antibodies.

Abstract: Monitoring devices, such as air particle counters, having mesh network capabilities are described for implementation in environmental monitoring within a facility. The air particle counters run samples at various facility locations based on a standard operating procedure (SOP). Each air particle counter can opportunistically connect with one or more other air particle counters using mesh networking. Data from samples run by and any new or updated SOP received at the air particle counters can be distributed via database replication across the other air particle counters using the mesh networking such that each air particle counter has a copy of the sample data and a current SOP within its database. A dashboard user interface displaying a hierarchical representation of the SOP and an associated compliance status with the SOP can be generated and updated based on data received from the air particle counters to facilitate SOP management.

Abstract: Embodiments of lab automation workstations are disclosed in which the pod that performs pipetting operations is integrated with pipette tip-loading functionality. To generate the necessary tip-loading force, a dual drive system is used that is symmetric about the Y-axis to allow for offset or partial tip box loads by dynamically centering the drive force (e.g., the tip-loading force) over the reaction load. This minimizes the need for oversized linear motion components while still allowing for the generation of high tip-loading forces needed to properly load a large number of pipette tips simultaneously.

Abstract: Embodiments may include an automated method for evaluating a sepsis status associated with a blood sample obtained from an individual. Methods may include determining a standard deviation of monocyte volume associated with the blood sample. Methods may include determining a white blood cell count (WBC) associated with the blood sample. Methods may include evaluating, using a data processing module, the sepsis status associated with the blood sample. The data processing module may include a processor and a computer application. This computer application may cause the processor to compare the standard deviation of monocyte volume with a first cutoff value to provide a comparison. The computer application may cause the processor to compare the WBC to a second cutoff to provide a second comparison. The computer application may also cause the processor to evaluate the sepsis status associated with the blood sample based on the first comparison and the second comparison.
