Ensuring Quality Standards with Compliance to UKAS Lab 51

At Lextox we are excited to announce that the United Kingdom Accreditation Service (UKAS) have confirmed our compliance to the Lab 51 quality standard. We are proud to be one of the first hair testing laboratories to have confirmation of Lab 51 compliance.

Lab 51 is a UKAS extension of ISO 17025 (the quality standard used to assess testing laboratories competence) that provides a technical framework to which laboratories performing analysis of toxicology samples should conform to.

Lextox has maintained its ISO 17025 accreditation, awarded by UKAS, for 10 consecutive years. The Lab 51 technical assessment involved an in-depth evaluation of the procedures within our Laboratory and Reporting Scientists teams. Compliance to Lab 51 further demonstrates our laboratory’s technical competence to undertake the analysis and provide accurate and reliable results.

“This is a fantastic achievement for Lextox and another chapter in our success. Quality underpins everything that we do, and this recognition is testament to the commitment to quality by everyone here at Lextox.”

Liam Feasey, Quality and Business Services Manager
