Abstract

Assay devices, systems, methods, and kits useful for detection of analytes in a bodily fluid sample, such as saliva, are disclosed herein. Assay devices may include a fluid sample collector and an assessment unit to which the fluid sample collector couples. The fluid sample collector may include a cap with a plunger and absorbent member that collects a bodily fluid sample. Insertion of the plunger into the assessment unit during coupling provides pressure-driven fluid flow through a filter rapidly delivering bodily fluid filtrate to one or more test panels which provide the assay result. In embodiments, an on-board light source enables a user to readily detect changes in a test panel indicative of the presence of an analyte thus providing an opportunity for obtaining rapid results with improved confidence.
