Inside the checklist
Use the same questions across suppliers and lots so polished presentation does not substitute for traceable evidence.
Connect the offered material, supplier lot, sample identifier, and laboratory report.
Record the laboratory, report number, dates, and available independent verification path.
Separate the analytical methods and results instead of treating one percentage as a complete finding.
Check whether the labeled amount is supported by a defined measurement and reporting basis.
Look for attribute-specific evidence when sterility, endotoxin, residual solvent, or stability claims are made.
Label missing evidence and contradictions without converting uncertainty into an automatic pass or fail.
What it helps establish
The worksheet helps you record what was reported, what can be connected, which claims have attribute-specific evidence, and what remains unresolved.
What it does not establish
A completed checklist is not independent product testing, a safety determination, a medical recommendation, or proof that a submitted sample represents every item in inventory.
