Abstract: The present invention provides an application of a melamine foam in sample collection or processing. A sampling head, a sampling block or a filter membrane prepared by using the melamine foam is used for collecting or processing a sample, which can significantly reduce adsorption of a target determinand or can significantly improve an elution effect of the target determinand to restore authenticity of the sample, thereby improving detection sensitivity of the target determinand and avoiding occurrence of false detection or missing detection.

Abstract: The present invention provides a detection device comprises a testing element and a transparent area, wherein the testing element comprises a detection area which is configured to detect a presence of an analyte in a liquid sample; the transparent area is configured to read the test result on the detection area through the transparent area; a part of the transparent area contacts a part of the detection area, or the detection area and the transparent area are arranged in one sealed space, thus to make the air in the sealed space not exchange with the air outside the sealed space; the scheme can reduce the mist to ensure the test result is displayed clearly.

Abstract: The present invention provides a detection device, and the device comprises a testing element, wherein the testing element comprises a detection area used for detecting a presence of an analyte in a liquid sample; and a transparent area through which the test result on the detection area is read, and the transparent area includes a hydrophilic area and a hydrophobic area. Thus, the detection device reduces formation of droplets on the transparent area is reduced, that is, it avoids formation of a mist layer on the transparent area; or avoids accumulation of small droplets on the transparent area, thus to make the result on the test area be clearly read.

Abstract: The present invention provides an apparatus for collecting and detecting liquid samples comprising a first chamber and a second chamber. The first chamber is used for collecting liquid samples for initial detection, and the second chamber is used for collecting liquid samples for second confirmatory detection. The first chamber and second chamber of the apparatus are detachable. When a second confirmatory detection is necessary, the second chamber can be separated from the first chamber, and then sent to a detection agency for confirmatory detection. It can avoid the contamination of liquid samples caused by contacting with test strip of a traditional apparatus; thus, it can effectively reduce the space required for storing liquid samples and greatly reduce the risk of leakage of liquid sampled during transportation.

Abstract: The present invention provides devices, methods and kits for detecting the presence of an analyte in a liquid sample. The invention provides devices having a positive control area covered with an opaque, movable material, such as an ink, dye, or other material, that is moved on the device by the flow of liquid sample, thereby exposing the positive control area underneath. Using the interaction of colored signals from the positive control area and the analyte binding area, a recognizable symbol is revealed on the device that correlates with the test results, and appears as the test is conducted.

Abstract: The present invention provides devices, methods and kits for detecting the presence of an analyte in a liquid sample and indicating to the user the presence or absence of the analyte through the formation of a recognizable symbol during the assay. In one embodiment, the present invention provides test strips having a matrix including a sample application zone, a reagent zone, and a detection zone. Within the detection zone are located positive and negative control areas, and an analyte binding area. The positive control area contains one or more components that exhibit a first color when dry and a second color when wetted. When the assay is conducted, the positive control area is wetted by the assay fluids and turns to a second color, thereby functioning as a positive procedural control. When analyte is present in the sample, it binds at the analyte binding area, which interacts with the positive control area to form a second recognizable symbol at the detection zone.
