Abstract: The present disclosure provides a device for testing an analyte in a fluid sample and a receiving device for treating the fluid sample, wherein the receiving device is used for receiving an absorbing element; the receiving device comprises a accommodating chamber and the chamber comprises a piercing element that is movable in the chamber, wherein the piercing element has a first position and a second position in the accommodating chamber, and configured to pierce the first sealed chamber; the accommodating chamber comprises a treatment solution for treating a fluid sample. The assay device and receiving device of the present disclosure treats a sample and quickly obtain the assay result, which is especially suitable for quick assay of a roadside drug.

Abstract: A screening device for testing saliva for the presence of certain constituents. The device has a D-shaped profile when viewed from above and includes a first wall with planar front face through which all of the test strips are viewed and a curved rear second wall. The device also includes a floor surface with an uppermost portion extending from the rear wall to a lowermost portion at the first wall such that saliva squeezed from a sampler at a location between the upper most portion and the lowermost portion flows downwardly to the test strips.

Abstract: In an embodiment, the claimed invention includes an oral-fluid collection and testing device that. is simple to operate. The device includes a body assembly and a cap assembly that are easy to handle by a user. A collection sponge projects from an end of the body assembly for absorbing the oral fluid of a donor, A cap assembly is easily aligned with the body assembly by way of visual alignment indicators on both the body and the cap. Once the cap is aligned with the body, a user simply pushes the cap onto the ‘body, which causes a first stage fluid, flow. More specifically, a buffer fluid is released from the cap and mixes with the oral fluid collected on the sponge—After waiting a short time* the cap is rotated, then pushed again, causing a second-stage fluid flow in which the sponge is compressed such that the buffer fluid/oral fluid exits the sponge and flows toward a. pair of test strips.
