Possibly NSAIDS: Motrin and other meds in that class, nsaids "can" infrequently result in a false positive. Some patients may be taking meds. Which contain barbiturate but they are not aware of it, such as "fioricet". Random urine drug tests usually include an initial screening test, sensitive to detect substances but sometimes false pos., these must always be sent for confirmation.
