A mixed bag: Plain Advil would not be an issue at all - but the PM part has benadryl that might cause a false positive in certain tests. Even that should be okay after a full day or two since the last pill (half life short) but bring the bottle w/ you to reflect the cause if there's a problem. They should be familiar w/ this common issue. Try to feel innocent if you really are! Best wishes.
