Reduction of false positives in oral-fluid based immunoassays
First Claim
1. A method of reducing false positives in assays for the detection of an analyte in an oral fluid sample, said method comprising the step of providing an oral fluid sample combined with a bile acid bile or salt;
- wherein said bile acid bile or salt is present in a concentration sufficient to reduce the rate of occurrence of false positives in said assays; and
wherein said assays are characterized by the use of a particulate moiety as a detectable label.

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.
