Cansford Laboratories conforms to the highest standards of laboratory accreditation across our test portfolio, while investing in and advocating for better standards in the drug and alcohol testing sector globally.

What laboratory accreditation should you look for?

Laboratories can claim to be accredited by a range of bodies, but some certifications are more relevant than others.

The ISO 17025 standard that Cansford Laboratories’ test processes meet is the most appropriate for UK drug and alcohol testing laboratories, and is awarded by the Government certification body, UKAS (United Kingdom Accreditation Service).

It’s important to note, however, that ISO 17025 is awarded on a substance-by-substance basis. As such, a laboratory can claim ISO 17025 accreditation for their test processes, even for only one substance that it tests for.

When choosing your laboratory, use the UKAS schedule search tool to check that the company is accredited to test for a wide range of substances, including your target substance and the relevant metabolite.

Cansford Laboratories is accredited to ISO 17025 standard for testing for the following drug groups and metabolites:

Our accreditation and performance

ISO 17025

ISO 17025 addresses an laboratory’s ability to produce precise, accurate and reliable results. Laboratories are re-examined annually to assess:

  • The technical competency of staff;
  • The validity of their methods;
  • Traceability of measurements and calibrations to national standards;
  • Appropriate application of measurement uncertainty at cut-off levels;
  • Suitability, calibration and maintenance of test equipment;
  • Quality assurance of test, inspection or calibration data;
  • Customer service;
  • Adherence to continuous internal auditing, and;
  • Successful participation in Proficiency Testing

ISO 9001

Testing and calibration laboratories whose test processes comply with the ISO 17025 standard automatically meet the principles of ISO 9001.
