A new entrant — the website's pages were published in June 2026 — with a public batch-verify portal that works, an Austin street address, and an 'unannounced independent testing' project that buys products on the open market. What it does not yet print is a legal entity, an accreditation, or a track record longer than a few months.
'Laboratory: 807 Brazos St, Austin, Texas 78701' on the contact page; phone +1 201-357-0230 (a New Jersey area code). No registered company name (LLC/Inc) printed on the pages we read; the site signs its about page 'The N.A. Diagnostics Team'.source
None claimed. The site describes 'literature-based methodology on professional-grade instruments' and 'trained analytical chemists'; it does not mention ISO/IEC 17025, GLP or any accreditor, and we found no A2LA listing.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.
Batch lookup on the lab's site (JavaScript required); certificate PDFs are vendor-hosted.
Open the lab's verification pageThe test that matters: does the lab's own system return the same report the vendor showed you, for the same lot that is on your vial? A PDF on a vendor's site is a claim. The lab's record is the evidence.

"Served by the lab" means the certificate we opened was returned by the lab's own verification system, not only hosted on the vendor's site. Every certificate is in the COA library.
It is a real, reachable operation with a working public batch-lookup and an Austin street address, launched in mid-2026. It has no accreditation and prints no legal entity, so our reading is legitimate with caveats: trust the batch record you can pull from the lab's portal, and weigh the short track record.
Enter the batch number (e.g. NAD-0037963) on nadiagnostics.com/verify. The lab's page shows purity, identity and measured mass for that batch; compare it with the vendor's PDF and with the lot on your vial.
No accreditation is claimed on the site and we found none in the A2LA directory.
