Abstract
A saliva sampling device includes an expresser cup, an absorbent foam swab capable of absorbing a fluid specimen, and a flexible tether affixed to the foam swab. The foam swab is used to collect a sample of a fluid specimen such as saliva, and the tether is adapted to enable a user to sanitarily draw the saturated foam swab into the expresser cup in which the foam swab becomes compressed: and the absorbed fluid is expressed therefrom in a drop by drop fashion. The device also may include a platform having a reagent strip for absorbing the expressed fluid to reveal test results. The device may also include a divider for separating the expressed fluid into two or more aliquots prior to the testing thereof such that one of the aliquots may be used for confirmation or later testing of the fluid. In one embodiment, the expresser cup includes a conical cross section to effect gradual compression of the foam swab.
