Toxicology (TOX)
"Our toxicology proficiency testing scheme - giving you confidence in the measurement of your results" 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. It is vital for laboratories that these analyses provide confidence and that results are meaningful and accurate.
At AXIO Proficiency Testing we recognise the importance of getting this right and providing meaningful and accurate results. This is why we designed TOX, our Toxicology proficiency testing programme, to provide an independent performance assessment of laboratories undertaking clinical and/or forensic toxicological analytical services.
The operation of our TOX 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 UK participants (who have clinical responsibilities) to the National Quality Assurance Advisory Panels for Chemical Pathology.
