Abstract: A method of producing a binding assay device provides a porous membrane comprising a material enabling capillary movement of a liquid sample from a first area on the membrane on a second area on the membrane. A detection site is disposed on the membrane between the first and second areas in a non-absorbent medium disposed on the membrane between the detection site and the membrane first area is attached by an adhesion with a dry reagent disposed between the medium and the membrane in order to enable mobilization of the reagent by passage of a liquid sample therepast.

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.

A captive reagent is immobilized on the strip on a path of sample migration and the captive reagent is formulated to bind to the labeled reagent to form a visible colored site on the strip. An element is provided for changing the strip to a color which enhances visual perception of the colored site.

Abstract: A drug testing urine collection cup includes a cup body having a top bottom flat sidewall with the flat sidewall being transparent. At least one test strip is provided for assaying a fluid sample and visually displaying an assay result. A disk sized for insertion into the cup top for suspending a test strip into the cup body proximate the flat sidewall at a distance enabling visual perception of the assay through the transparent flat sidewall.

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.

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: An assaying device and a method of manufacturing same are provided. The assaying device includes a unitary, absorbent membrane having multiple reagent stripes incorporated therein. The reagent stripes display an observable reaction if a sample component is present in a fluid sample being tested. The reagent stripes are deposited simultaneously on a continuous membrane ribbon and individual membranes are die cut therefrom. Each individual membrane includes commonly connected channels having die cut slots therebetween. The channels are preferably disposed perpendicularly with respect to the reagent stripes and provide means for causing contact between the fluid and reagent stripes.
