Start with labeled identity
Begin with the exact tissue type, presentation, and storage class on the current insert. Catalog names help you find a SKU; they do not replace lot-linked identity.
Independent evaluations of commercial cord-tissue allografts have reported low cell counts and only rare viable stem cells. Precision Biologics does not represent these products as containing functional living stem cells or as stem cell therapies.
Unanchored marketing numbers
Treat particle counts or factor panels that appear only in brochures—not on the COA—as marketing, not lot evidence.
Reject or hold when product name, size, or lot on the COA disagrees with the vial or purchase order.
Missing methods
If critical tests lack method or lab identity, ask for completion before release.
Templates may look similar across SKUs; values must be lot-specific.
Outcome language does not belong on a COA
A COA should report analytical or sterility results. Language that implies patient outcomes does not belong on a COA.
Escalate outcome-flavored COA language to quality and counsel.
Frequently asked questions
Should price be the first filter?+
No. Filter first on documentation completeness and claim discipline, then compare price.
How many vendors belong on a shortlist?+
Two to three with complete packs is usually enough for a pilot.
What disqualifies a vendor quickly?+
Disease claims, undocumented live-cell promises, or refusal to provide lot-linked documents.
Does this page determine how we may use products discussed under certificate of analysis red flags?+
No. Intended use remains with the ordering physician and clinic counsel.
