DEVICES AND TECHNIQUES FOR ORAL FLUID COLLECTION AND SEROPROTECTION TESTING

Abstract:

Seroprotection analysis systems, kits, and techniques are described for testing oral fluid for the presence of protective levels of antibodies of interest. In one aspect, the presence of protective levels of target antibodies indicates a test subject has achieved a target seroprotection level, such as but not limited to a target seroprotection level following vaccination. A collection kit can include a swab that enables collection of oral fluid containing antibodies from both dentulous and edentulous individuals, a container that can be pre-filled with an extraction solution, and a nozzle that can be coupled to the container to form a fluid-tight device. A user can use the nozzle to seal the swab in the container and to compress the swab within the container. After or during compression, the solution can be dispensed from the fluid-tight device, such as by inverting the fluid-tight device to flush the swab with the buffer solution and to transfer the fluid to a detection device through a channel in the nozzle. The detection system can be an assay reader device.
