Rooting for Accreditation: who’s accredited for what?

Accreditation has been in the press recently.

Our Child Protection specialists, Concateno TrichoTech, first achieved the international quality benchmark for drug testing, ISO/IEC 17025, back in 2004, and every year has to submit to an independent audit from United Kingdom Accreditation Service (UKAS) in order to retain it. UKAS also reserve the right to visit accredited sites unannounced.

UKAS’s own statement on accreditation is clear:

“A laboratory accredited by UKAS to this standard has the competence, impartiality and performance capability that ensures you will receive the service that meets your needs. Accreditation to this standard also means a laboratory’s management systems meet the principles of ISO 9001:2008. A laboratory certified to ISO 9001:2008 but without ISO/IEC 17025 should not be considered a suitable alternative.”

We have long been requesting that the Ministry of Justice (MoJ) specifies that only UKAS accredited laboratories be used for child protection cases. In the same way the MoJ have published a list of approved DNA specialists, as part of their revision to the criteria for accreditation to ensure the soundness and reliability of DNA scientific evidence.

The Society of Hair Testing (SoHT) issues guidelines, not ‘standards’. The SoHT doesn’t currently regulate, inspect, or license hair testing laboratories; it is UKAS that inspects, audits and accredits laboratories for drug testing. Their website tells you who have achieved their accreditation, passed continued audits and the full specification of what it actually covers, such as a range of drugs –
