What Should Be on a COA

A checklist for evaluating whether a supplier's documentation is complete — or quietly incomplete.

The Checklist

  1. Lot number matching the physical vial — not a generic document ID.
  2. Donor/source information — tissue type and origin, with applicable screening standards referenced.
  3. Manufacturing facility identification — including an FDA facility registration number (FEI), not just a brand name.
  4. Identity / characterization panel — confirming cell type via marker analysis, specific to the lot.
  5. Viable cell count — an actual number, with the counting method listed (see How Stem Cell Counting Works).
  6. Post-thaw viability percentage — measured after the freeze/thaw cycle, not before (see Why Post-Thaw Viability Matters).
  7. Sterility results — with the test method and incubation period noted.
  8. Cryopreservation medium — named specifically, matching what's actually in the vial.
  9. Signed, dated release approval — a named individual with a stated title, not an unsigned template.

The Gap to Watch For

The single most common gap isn't a missing document — it's a missing number. A supplier can provide a professionally formatted packet that includes a sterility panel, an infectious disease screen, and a generic spec sheet, and still never state an actual post-thaw viable cell count for the lot being shipped. All three of those documents can be genuine and still not answer the question that determines clinical relevance.

If a cell count or viability figure is present but not tied to a specific lot number, treat it as a marketing claim rather than a test result — it may describe a different batch, an average across batches, or a target specification rather than what's in the vial.

Checked Against Every Line

ATOM Certificates of Analysis are built to include every item on this list for the specific lot shipped — lot-matched viable cell count, post-thaw viability, identity panel, sterility, and a signed, dated approval from a named QC signatory.
