Laboratory Information

Many factors influence the selection of an analytical laboratory.

Air Sampling Machine and Computer in Stanford LabA laboratory should be selected that participates in Laboratory Accreditation Programs such as the International Laboratory Accreditation Cooperation (ILAC), American Industrial Hygiene Association Laboratory Accreditation Programs (AIHA-LAP), American Association for Laboratory Accreditation (A2LA) and/or the National Voluntary Laboratory Accreditation Program (NVLAP). You may ask laboratories to provide documentation of accreditation by these and other organizations.

Other factors to consider when selecting a laboratory include:

  • Does the laboratory perform the required analysis?
  • What are my requirements for quality assurance and does the laboratory quality assurance meet these requirements?
  • Does the laboratory analyze samples and report results within my required turnaround time?
  • Does the analytical report contain the information I need?
  • Are detection limits reported and are they sufficiently low?
  • Are analytical costs acceptable?
  • Does the laboratory provide the client services I desire?
  • Am I confident in the results provided?
