An all-in-one self test kit includes: a test tool having a reagent container adapted to store a diagnosis reagent therein and a diagnosis kit with a casing constituted of a first body and a second body and a diagnosis strip disposed inside the casing and having a sucking part for sucking the diagnosis reagent and a diagnosis part reacting to the diagnosis reagent sucked to the sucking part; a sub-body having a container insertion portion for inserting the reagent container thereinto and a kit insertion portion for inserting the diagnosis kit thereinto; a main body for inserting the sub-body thereinto; and a cap fastened and unfastened with an entrance of the main body to open and close the main body.

The invention provides devices that improve tests for detecting specific cellular, viral, and molecular targets in clinical, industrial, or environmental samples. The invention permits efficient detection of individual microscopic targets at low magnification for highly sensitive testing. The invention does not require washing steps and thus allows sensitive and specific detection while simplifying manual operation and lowering costs and complexity in automated operation. In short, the invention provides devices that can deliver rapid, accurate, and quantitative, easy-to-use, and cost-effective tests.

There is provided a sample processing cartridge comprising a. a sample entry location; b. a closed sample processing chamber; c. a sample analysis location comprising a sample analysis well; d. a first channel fluidly connecting the sample entry location and the sample processing chamber; e. a second channel connecting the sample analysis location and the sample processing chamber, the second channel comprising a closed or closable second channel valve;
wherein the sample processing chamber comprises a second channel port providing fluid connection between the second channel and the sample processing chamber, the second channel port being positioned in a sample accumulating region of the sample processing chamber.

There is also provided a sample processing system comprising the cartridge, and methods of use of the cartridge and processing system in a sample processing assay.

The present disclosure provides systems, methods, devices, and kits for analysis of vaginal biological samples. A device for the analysis of vaginal biological samples can include a sample collector, an extractor, and an assay cartridge. A method for the analysis of vaginal biological samples can include detecting the presence or absence of a pathology, a disease, an immune disorder, a reproductive disorder of a subject. The method may further comprise preserving, storing, or transporting the vaginal biological samples. A kit for the analysis of vaginal biological samples can include probe, reagents and instructions for detecting a nucleic acid in the vaginal biological samples.

Disclosed is a sample collection and detection card. A lower cover of the card is provided with a sample loading chamber capable of accommodating a sampling part of a sampling end, an outlet is arranged at a bottom of the sample loading chamber, and a sample loading area of a test strip is located at the outlet; a fixing structure for fixing a sampling rod to a box is further arranged between the box and the sampling rod, and the sampling part is deformable when the sampling rod is fixed to the box. In embodiments of the present disclosure, the sample loading chamber is arranged on the lower cover, and the sample loading area of the test strip is arranged at the outlet of the sample loading chamber.

A sample collection and detection device includes a collection cavity. The device further includes a sample collector. The sample collector comprises a collection rod and an absorption element, and the absorption element has a hollow cavity. A part of the collection rod is received in the hollow cavity of the absorption element. A first lug for blocking and locating the absorption element is arranged on the collection rod. Also provided is a method for collecting and detecting sample using the sample collection and detection device.

A sample extraction cassette and method are provided to test for a target in a sample. The sample is obtained on a swab. The swab is inserted into a chamber in a case and into contact with a contact portion of a membrane. The contact portion of the membrane is axially moved into sequential communication with a wash fluid and a reaction fluid. The reaction fluid reacts with the target to provide a visual display corresponding to the presence of the target.

The invention relates to a system is provided that comprises a first container, a second container and a fluorescence detection device. The first container comprises a first set of chemicals and/or agents and is closed prior to use. The second container comprises a second set of chemicals and/or agents that are at least in part distinct from the chemicals and/or agents of the first set. The first container comprises a lid, that can be opened when the first container and the second container are combined to form a single, fluid tight assembly, in order to allow the contents of the first container to enter the second container.
