Toxicology (TOX)

daps UKAS Logo
  • UKAS accredited proficiency testing scheme
  • The LGC Toxicology (TOX) proficiency testing scheme is designed to provide an independent performance assessment of laboratories undertaking clinical and/or forensic toxicological analytical services.
  • Toxicological analyses may be undertaken on biological specimens, predominantly blood, serum and urine. In general, analyses are undertaken for a range of substances including prescription and non- prescription drugs, illicit drugs and alcohol.
  • For laboratories performing these analyses, participation in TOX can provide confidence that results are meaningful and accurate.
  • The operation of our TOX scheme is supported by an Advisory Group consisting of members of the 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
