摘要： The invention relates to a method for detecting a dengue infection in a patient blood sample, comprising the steps: a) Performing an analysis of prespecified parameters of blood platelets and prespecified types of blood cells in the sample and determining parameter values for the prespecified parameters of the platelets and the prespecified types of cells; b) Obtaining sample parameters from the values determined in step a); and c) Evaluating the sample parameters in relation to a prespecified criterion, wherein, if the criterion is fulfilled, a dengue infection is present.

摘要： A sample holder for PCR processing. The sample holder includes a body with an inlet and outlet grooves formed alongside each other, a detection recess that is connected to the inlet and outlet grooves, and a fill port interconnected to both the inlet and outlet grooves, and a cover interfacing with the body to form an inlet channel interconnected to the fill port, a detection region interconnected to the inlet channel, and an outlet channel interconnected to the detection region and the fill port. The detection region is configured to receive a PCR solution from the fill port and replication occurs within the detection region via heating and cooling cycles. Thereafter, fluorescent emissions from tagged replicated DNA/RNA in the detection region are detected and measured. PCR stations, PCR station assemblies, PCR testing systems, and methods of operating a PCR testing systems are provided, as are other aspects.

摘要： Methods of autonomous diagnostic verification and detection of defects in the optical components of a vision-based inspection system are provided. The method includes illuminating a light panel with a first light intensity pattern, capturing a first image of the first light intensity pattern with a sensor, illuminating the light panel with a second light intensity pattern different than the first light intensity pattern, capturing a second image of the second light intensity pattern with the sensor, comparing the first image and the second image to generate a comparison of images, and identifying defects in the light panel or the sensor based upon the comparison of images. Systems adapted to carry out the methods are provided as are other aspects.

摘要： A method of calibrating an imaging device adapted to characterize a feature of a sample container, such as a cap color or cap type. The method includes providing a calibration tube including an imaging surface at an imaging location of a first imaging apparatus; illuminating the imaging surface with light emitted from multiple front light sources; adjusting a drive current to each of the multiple front light sources to establish a substantially uniform intensity of the imaging surface; recording drive current values for the multiple front light sources; replacing the calibration tube with a calibration tool having a calibration surface of a known reflectance; and measuring target intensity values of the calibration tool at the respective drive current values. Calibration tools, imaging apparatus, quality check modules, and health check methods are provided, as are other aspects.
