Abstract
The utility of oral fluid as a sample matrix for the analysis of drugs has been increasing in popularity over the last few years. This is largely because of collection advantages over other matrices, but also due to the rapid improvements in analytical assays including highly sensitive liquid reagent format enzyme immunoassays and LC–MS/MS. This review will highlight improvements in assay formats, sensitivity, laboratory equipment and sample processing using low sample volumes to expand drug test profiles.
