What is ISO 17025 Accreditation and why is it important?

ISO 17025 is the key standard for an analytical laboratory. It provides absolute confidence that if contamination exists above the defined limit of detection, then it will be identified and called “positive”.

Laboratories that do not meet this standard may call a “negative” simply because they are unable to find the contamination, NOT because it is absent. Their techniques may be wholly inadequate.

Analysis is of no value unless it meets the exacting requirements of the various regulating bodies.

Lifespan International (the parent company of Xendurance) uses HFL Sport Science to test products because HFL understands the importance of integrity, and analytical methods for supplement analysis to meet the requirements of:

  • ISO 17025 (international standard for analytical laboratories)
  • GLP (Good Laboratory Practice)
  • GMP (Good Manufacturing Practice)

Results are therefore dependable, and will withstand scrutiny in High Court, in any jurisdiction around the world.
