Utilidad de las técnicas de cribado de tóxicos en orina solicitadas desde el servicio de urgencias de un hospital pediátrico

Most of the drug screening tests are not justified, and it is very infrequent that they change patient management. It is very rare that the results are confirmed using more specific methods. Urine drug screening tests should be restricted to particular cases and if the result has legal implications, or if the patient denies using the drug, it should be followed by a specific toxicological study to provide a conclusive result.
