Abstract
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.
