Editor, – The article by Dimitri Gerostamoulos (Aust Prescr 2013;36:62-4) omits to mention the limitations of urinary drug screening.
Urinary drug screening does not identify the use of synthetic narcotics such as pethidine and fentanyl, a class of prescription drugs which are often abused. Most doctors do not know this.
These drugs can be detected and confirmed by hair analysis which is not mentioned in the article.
Sometimes incomplete coverage of the important issues related to an article can, by virtue of their omission, be problematic.
