Use the checklist with the original report
Review the original supplied file rather than a cropped image or summary. Record what is present, mark what is missing, and keep the exact lot identifier with your receiving and study records.
What this review can establish
The worksheet helps document whether the report identifies a sample, lot, issuer, methods and results. It does not independently authenticate the document or establish an attribute the report did not test.
A COA covers only the tests, sample and lot listed. An omitted test is not evidence that the unreported attribute passed.
Review worksheet
- Material name or identifier is present and unambiguous.
- Lot or batch identifier exactly matches the container and receiving record.
- Issuing laboratory or organization and a usable contact channel are identified.
- Report or document number is present and retained with the original file.
- Report date, sample date and test date are recorded when supplied.
- Each analytical method is named; relevant method conditions are retained when supplied.
- Numerical results are recorded rather than relying only on ‘conforms’ or ‘passes’.
- Acceptance limits or specifications are recorded when the report provides them.
- Chromatogram, spectrum or other underlying plot is present when referenced.
- Observed and theoretical mass values, charge states and tolerance are reviewed when applicable.
- Purity is not treated as net content or total container amount.
- Every missing or unreported test is listed as not reported, not assumed acceptable.
- Reviewer, review date and follow-up questions are recorded in laboratory notes.
