Key takeaways
- Compare the material or sample name, lot number, laboratory, COA number, and report date. [2]
- CellSyntax report pages include a Verify at Lab link when a public laboratory record is available. [1]
- A matching lab-hosted record establishes that the laboratory publishes a record with the compared identifiers and results. [1]
Where should COA verification begin?
Begin on the specific COA report page rather than a product image, marketing card, or general library index. The report should identify the material and show the posted document connected to it.
If multiple strengths, formats, or lots exist, confirm that you selected the record tied to the one you mean to review. Similar names are not enough.
Which identifiers should match?
Compare the material or sample name, lot number, laboratory, COA number, and report date. These fields should describe one consistent record across the CellSyntax report and the posted document image.
A missing or conflicting identifier should be treated as an unresolved document question. Do not use a purity percentage or other result to bridge an identifier mismatch.
- Material or sample name
- Lot or batch number
- Issuing laboratory
- COA or web-verification number
- Report and sample-received dates
Where can you find the laboratory record?
CellSyntax report pages include a Verify at Lab link when a public laboratory record is available. Open that record directly or search the laboratory archive using the COA number shown on the report.
Confirm that the lab-hosted record names the same material, lot, date, and reported results. The point is not that a verification button makes a document trustworthy. The point is that the second record can be compared with the first.
Which methods, values, and units should you compare?
Review the identity method, purity method, reported values, and units on both copies. If endotoxin, heavy metals, content, or another field is shown, compare that field separately rather than treating it as part of the purity percentage.
A reformatted summary can help navigation, but the laboratory record remains the source for the values it reports. Any discrepancy should be resolved against the source record instead of silently normalized.
What does a matching record establish?
A matching lab-hosted record establishes that the laboratory publishes a record with the compared identifiers and results. It does not by itself establish the chain of custody between the tested sample and every packaged unit.
It also does not establish sterility, suitability, instructions for use, or results that are absent from the document. Verification should make the record more checkable, not make the claim broader.
What should you do when records do not match?
Stop at the mismatch. Record which field differs and contact the document issuer or CellSyntax for clarification. Do not substitute another lot's document or infer that two records are equivalent.
A clear unresolved status is better documentation than a confident conclusion unsupported by the record.
