Description:Advanced Search Abstract The initial screening for drugs of abuse invariably poses the risk for false positives due to cross-reactivity. It is believed that DXM can also cause a false positive for opiates, presumably due to structural similarities. This could have serious implications, as DXM abuse is reported to be increasing. However, many of these claims are anecdotal, as no fully comprehensive studies exist. Furthermore, what studies have been completed reveal that DXM does not cause a false positive for opiates, despite their similarity in structure. Laboratories have established cut-off limits for opiates for the initial screen, and like all presumptive positives, confirmation with more sensitive methods are strongly recommended to rule out false positives.
