Abstract
A device for collecting oral liquids includes a lateral flow chromatography strip having a collection member. The collection member is separated from the remainder of the chromatography strip by a liquid impermeable removable barrier which prevents liquid in the collection member from entering the chromatography strip. Once adequate oral liquid has been collected (as indicated by a sample sufficiency indicator), the barrier is removed to allow oral liquids to flow through the strip. The liquids interact with binding partners in the strip to provide test results, such as an indication that an analyte of interest is present in the liquid. The strip may be contained in a housing with an access opening through which the removable barrier may be manipulated, and windows through which test results may be viewed. This device avoids reflux of reagents from the strip into the mouth of a test subject during use.
