The diagnostic devices may include a sample chamber; a fluid chamber connected to the sample chamber by a conduit; and a test chamber separated from the sample chamber by a breakable seal. A movable liner may form a portion of an inner surface of the sample chamber. The sample chamber may be configured to receive a sample swab, which may move in a first direction when being inserted in the sample chamber to an inserted position, and which may to move in a second direction to cause the breakable seal to break. Movement of the sample swab in the second direction may cause the liner to move in the second direction to break the breakable seal.

Abstract: Diagnostic devices for performing diagnostic tests are provided, as well as methods that utilize the diagnostic devices, methods for manufacturing the diagnostic devices, and test kits for performing the diagnostic tests. The diagnostic devices include a vial, a rupturable container disposed in an internal cavity of the vial and containing a fluid, and a test and readout device in fluid communication with the internal cavity of the vial. The rupturable container is configured to rupture during a test procedure of the diagnostic test to enable the fluid to flow into the internal cavity of the vial. The rupturable container may include a rupturable ampoule or a frangible seal. The rupturable container may be ruptured by deformation of the vial or by piercing caused by a sharp object in the vial or a sample swab inserted in the vial.

Abstract: Described herein in an embodiment is a lateral flow assay strip for detecting the presence of one or more target nucleic acid sequences (e.g., one or more nucleic acid sequences of a pathogen, such as a coronavirus or an influenza virus). The lateral flow assay strip may comprise a first test line configured to detect a first target nucleic acid sequence and a flow control line configured to detect a liquid. In some cases, the first test line comprises a biological capture reagent (e.g., an immobilized antibody). In some cases, the flow control line comprises a non-biological fluid indicator (i.e., a non-antibody reagent). The non-biological fluid indicator may, for example, comprise a pH-sensitive material, a moisture-sensitive material, and/or a chemically-sensitive material. The flow control line may provide a visual indication of whether a fluidic sample was successfully transported from a first end of the lateral flow assay strip to the first test line.

Abstract: 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.
