    摘要: This invention relates to the use and composition of materials which, when added to oral fluid samples, make such samples suitable for use with microparticle-based immunoassays. In one embodiment, this invention provides a method of reducing false positives in assays for the detection of an analyte in an oral fluid sample. The method involves providing an oral fluid sample combined with a bile acid or salt where the bile acid or salt is present in a concentration sufficient to reduce the rate of occurrence of false positives in said oral fluid based immunoassays.

    摘要: A method of assaying a preselected volume of sample on an chromatographic strip includes providing a sample receiving reservoir. This reservoir can receive a preselected volume of sample or a preselected volume of sample and reagent. The sample receiving reservoir has an overflow outlet. A moat is communicated to the overflow outlet of the sample receiving reservoir for receiving the sample or sample and reagent when the sample receiving reservoir is full. The mixed sample or sample and reagent fill the sample receiving reservoir, and discharge the excess sample through the overflow outlet to the moat. The sample receiving reservoir having the preselected volume of sample or sample and reagent is discharged on the chromatographic strip for assay. Provision is made for adding a density adding solute which is neutral to the chromatographic strip, the density adding solute occupying the sample receiving reservoir. As a consequence, dense sample first occupies the sample receiving reservoir with less dense excess sample being rejected.
