Abstract: A multiple analyte assaying device includes a casing having a pocket portion adapted to capture or contain a predetermined volume of fluid specimen to be assayed. Disposed within the casing is a sample receiving pad and one or more reagent test strips. The pocket portion of the casing includes a feed element having multiple feed inlets, or alternatively, a single feed slot. The feed element provides pressure against the sample receiving pad. The pressure against the pad and a small size of the inlet or inlets are effective in controlling a rate of fluid release of the specimen to the sample receiving pad. The casing includes observation windows or alternatively a clear plastic view area for enabling observation of reagent zones of the test strips. The device is structured and adapted to enable a technician to capture the appropriate volume of fluid specimen in the pocket portion by submerging or dipping a portion of the device into a fluid-filled collection container for a brief period of time.

Abstract: A lateral flow testing device is provided for testing a biological fluid for the presence of methamphetamines. The device includes a substrate element such as a nitrocellulose strip, including an antibody zone and an immobilized drug conjugate zone for detecting presence of methamphetamines, and an on-board chemical reactant for preventing undesirable cross-reactivity to ephedrine and/or pseudoephedrine that may be present in the biological fluid being tested. Preferably, the on-board chemical reactant is sodium periodate. Methods for preparing test devices are provided including the step of striping a substrate sheet with a solution containing sodium periodate during manufacture of methamphetamine lateral flow test strips.

Abstract: A saliva testing and confirmation device generally includes an expresser cup adapted to receive and compress a foam collection swab pressed into the cup. The swab includes a sponge or foam portion capable of absorbing a fluid specimen such as saliva, and a generally rigid handle for facilitating manipulation thereof. The device also includes a testing and confirmation platform integral with the expresser cup. A channel or groove in the cup is provided for directing a flow of expressed fluid from the expresser into both a test well and a confirmation well. A lateral flow reagent test strip, in fluid communication with the test well may be encased in the platform and partially revealed for analysis of test results. The confirmation well includes a fluid tight cap having a tamper evident seal.

Abstract: A solid phase extraction plate includes a unitary tray having a plurality of spaced-apart discrete upstanding chambers molded therein with each chamber having a top opening and a bottom nozzle with downwardly tapering sidewalls extending between the top opening and the bottom nozzle. A plurality of solid phase extraction disks are provided and one secured in each of the plurality of chambers without the use of frits or retainer rings utilizing instead tapered sidewalls of the chamber for enabling a press fit of the disks therein.
