SALIVA ASSAY METHOD AND DEVICE

摘要

An improved method for determining the presence of an analyte in an oral flu id sample. In the method, a reaction mixture is produced containing at least a portion of the collected sample and a chromogenic subs trate effective to produce a colored product upon reaction with amylase present in the sample. After a selected reaction time, the reaction medium is inspected to determine the level of colored product produced in the medium within the selected reaction time. Production of colo red product above a preselected threshold level within the selected reaction time indicates that an effective volume of undiluted saliv a sample has been collected sufficient to allow detection of the analyte. The invention also includes a device for use in the method.
