The only lab on this list whose accreditation we confirmed in the accreditor's own directory: A2LA certificate 6377.01, ISO/IEC 17025:2017, current to 30 September 2027. The accredited field is Biological Testing, so whether a given peptide HPLC method sits inside the accredited scope is a question for the scope document, which the lab itself says to ask about.

Confirmed in the A2LA directory on 9 October 2026: certificate 6377.01, Olympic Analytical, LLC DBA Vanguard Laboratory, Olympia WA, ISO/IEC 17025:2017, 'Biological Field of Testing', commercially available, expiration 30 September 2027. The certificate image on the lab's own site is an older print (presented October 2021, 'valid to September 30, 2023'); the directory shows the accreditation has been renewed. Note the field: Biological, not Chemical. The lab's homepage says 'accreditation applies to the methods in our accredited scope — ask which methods apply to your sample', which is the right question to ask before treating a peptide purity result as an accredited one.source
Why it matters: ISO/IEC 17025 is the standard that accredits a laboratory's competence to run a specific test method, assessed by a third party (A2LA, ANAB, UKAS and the like) with a published scope. "ISO 9001", "GLP principles" and "certified" on a website are not the same thing. An unaccredited lab can do accurate work; it just cannot prove it to you the same way.

Yes. Olympic Analytical, LLC dba Vanguard Laboratory is listed in the A2LA directory with an active ISO/IEC 17025:2017 accreditation (certificate 6377.01, Biological field, expiring 30 September 2027) at a street address in Olympia, Washington, and runs a public COA search.
It holds ISO/IEC 17025:2017 accreditation in the Biological Field of Testing. Whether a peptide HPLC purity method is inside the accredited scope depends on the scope document; the lab's own site says to ask which methods apply to your sample. An accredited lab can still issue non-accredited results for methods outside its scope.
