9 results about "Rapid diagnostic test" patented technology

Disclosed is a test system (100) comprising a test apparatus (100, 400). The test apparatus includes a pool (102) having a volume and an inlet (106, 408) for filling the volume with a test fluid (108, 414). An inner surface (114) of the pool comprises an amount of a viscosity modifying reagent (110, 410) in a dried format. The system also includes an immunochromatography assay strip (104, 502). The viscosity modifying reagent comprises a viscosity-removing salt. The salt is configured to precipitate a viscosity-causing substance present in the test fluid. The immunochromatography assay strip is to be entered through the inlet to be in contact with the test fluid, when in use. The system facilitates processing of viscous fluids such as saliva for rapid diagnostic testing using lateral flow-based assays.

A visualizer for use with an immunoassay rapid diagnostic test (RDT) with fluorescent probes includes a housing sized to enclose the RDT, an opening in the housing for insertion of the RDT, a viewing window in the housing positioned to align with a result window in the RDT when inserted in the housing, a UV / visible / infrared light source inside the housing for illuminating fluorescent probes in the result window so they may be viewed through the viewing window, and a switch for activating the light source. An RDT incorporating a UV / visible / infrared light source within its housing is also disclosed.

Computer systems and computer-implemented methods for a rapid diagnostic test result interpretation platform employing computer vision are disclosed herein. The system may visually analyze the test device in real time by receiving an image stream of the test device from the camera system. A detection system may be used to identify test results in the test area. In some embodiments, the test results are binary (e.g., positive / negative). In some embodiments, the test results are in a semi-quantitative format (e.g., 1-10). The test results may be sent back to the user, operator, HMO, or physician for further confirmation, recording, and medical processing decisions / follow-up. The detection system may close a loop between a user of the test device and the HMO / physician for recording test results and providing medical processing / follow-up.

A reagent carrier includes: a cap configured to fit on an opening of a reaction vessel; and a reagent confined by the cap. The cap may be configured to release the reagent when a user manipulates the cap while the cap is fitted on the opening of the reaction vessel. For example, the reagent may be released when the user twists the cap from a first position to a second position or when the user pushes on a surface of the cap. The cap may be configured to seal the opening of the reaction vessel when the cap is fitted on the opening of the reaction vessel. In some implementations, the cap may be a blister cap containing the reagent. In some implementations, the cap may include a cage containing the reagent. In some implementations, the cap may include a deformable structure containing the reagent.

Urinary tract infections (UTis) remain one of the most common bacterial infections worldwide, and they are becoming increasingly resistant to many first-line antibiotics typically prescribed to treat these infections. Multidrug resistant bacteria were once limited to the walls of hospitals and now are rampant in the communities. Provided herein are reagent tests that can be used to identify specific types of antibiotic resistant microorganisms in a sample, and methods of use thereof.

A framework for a few-shot learning method is disclosed. In a first part, self-supervision and classification supervision are used to train a feature extractor. An example self-supervision method comprises running grayscale images through an edge filter, normalizing the filtered images, setting the normalized images to ground truth, generating feature-extracted images, using a decoder to reconstruct images from the feature-extracted images, determining a loss between the reconstructed images and the ground truth images, and using the loss to update parameters of the feature extractor. In a second part, a few-shot adaptation process is performed to adapt the model to a novel rapid test kit.
