information

The Proficiency Testing schemes we offer help provide testing laboratories with the evidence necessary to prove that their tests meet third party accreditation quality standards. Participation in a PT scheme shows a commitment to improving performance, which is of commercial value in maintaining a good reputation for delivering reliable and accurate results. It is an independent and confidential verification of the testing process.

Inter-laboratory comparability, amongst national and international participants, within many schemes is an important factor which can be assessed to highlight consistencies between laboratories.

VETQAS® is the international market leader in Proficiency Testing (PT) for veterinary laboratories. It is a UKAS accredited proficiency testing provider No. 0004. Please view schedule of accreditation.
