Pharmacy/false positives


Can dextromethorphan cause a false positive for hydromorphone ?

Hi Douglas,
In my experience such false positives will not occur. There is a vast difference in the chemistry of both the molecules, hence corss reaction is just not possible. This is irrespective of what a number of sites will tell you.
