Revalidated 8 Sep 2026: Vanguard printed the lot as 7/27/1904 (a spreadsheet date for 1670); lot set to 1670 per submission #66572. 'Bacteriostatic Water' is the lab's name for this reconstitution solution.
Content audit 9 Sep 2026: size all sizes → #42219 10ml. Certificate prints: prints compound "Bacteriostatic Water", lot "7/27/1904", lab id "V260217-21 001", content
Content audit 9 Sep 2026, second pass: size 42219 → all sizes. Back to every size, for the same reason as the other lot 1670 certificate (sterility re-test of the same lot).

ConformityNot assessable
every reported unit passed on all 1 test rows · QA approval corroborates: Vanguard Laboratory, Tori Johnson, Operations Manager, 2026-03-10 · house check · agreement across all tests, unit to unit; QA approval corroborates

A chapter number names the method or limit a result follows; it does not describe the product. Chapters below 1000 are procedures or limits; 1000-series chapters are informational. USP <905> is the compendial test for between-unit uniformity: it assays 10 units, so a 3-unit certificate cannot yield its acceptance value — the content row is a house check with <905> named as the reference only.
