You may ask laboratories to provide you 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 requirments 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?  What extra charges to I accept to obtain sample results faster?
  • 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?

These questions represent basic questions that should be considered when selecting a laboratory.
