daps UKAS Logo
  • UKAS accredited proficiency testing scheme
  • The LGC Drugs of Abuse in Urine (DAU) scheme is designed to provide an independent performance assessment of laboratories and clinics that provide routine services for detection of drugs of abuse in urine.
  • Human urine has been used for many years to detect the presence of illicit drugs. Urine testing may be requested for a variety of reasons, including health care, occupational monitoring, insurance screening, legal and forensic purposes. Errors in tests could have severe consequences, such as dismissal from work or miscarriage of justice.
  • Laboratories and clinics are encouraged to participatein suitable PT/EQA schemes to ensure the highest standard of drug testing is achieved through independent assessment of measurement quality.
  • The operation of the LGC DAU scheme is supported by an Advisory Group consisting of members of professional bodies, scheme participants, and others experienced in the field. The scheme reports on the performance of U.K. participants (who have clinical responsibilities) to the National Quality Assurance Advisory Panels for Chemical Pathology.
  • Scheme operates from April to March
