What a certificate of analysis actually documents
A certificate of analysis is a lot-specific record, not a product brochure. It reports what a testing program found for one manufacturing lot of tissue or biologic material, tied to a unique lot number. Two vials from the same product line, pulled from different lots, can carry different certificates with different dates, test values, and reference ranges.
For licensed clinics and medspas, the certificate of analysis is the document that turns a purchasing decision into a documented one. It is the record a buyer keeps on file to show which lot was received, what was tested, and what criteria were used to release it before it shipped.
Reading the identifiers and chain-of-custody fields
Ask which identifiers and dates appear on the certificate and confirm it matches the lot ordered. Matching the paperwork in hand to the vial on the shelf is the foundation of lot traceability on the clinic side.
Request the donor eligibility summary alongside the certificate. That summary should reflect that donor medical and social history review and infectious disease testing were completed and met the supplier's release criteria.
- Lot or batch number matching the vial label
- Recovery and processing dates
- Expiration or retest date
- Confirmation that a donor eligibility summary is available
- Supplier or distributor name and contact for the document
Test values worth checking line by line
Ask whether samples from the lot were sent to a third-party laboratory for sterility testing, and whether any additional tests, such as endotoxin or bioburden, were performed. Look for a clear pass or fail determination against a stated acceptance criterion rather than a raw value without context.
A certificate should also indicate that the lot was held in quarantine until testing was complete and that it was released only after internal criteria were met. If a certificate is silent on quarantine and release status, that is a reasonable question to put back to the supplier before the next order.
Storage, handling, and format specifications
Format matters for how a certificate should read. If a product is cryopreserved, ask whether it was processed using slow-rate freezing and stored at around -80 degrees Celsius, then shipped overnight on dry ice in a validated container, and confirm the certificate or accompanying shipping documentation reflects that handling chain. Lyophilized, freeze-dried formats are described by some suppliers as shelf-stable without cryogenic storage, in which case the relevant documentation shifts toward reconstitution instructions in the product insert rather than cold-chain data.
Buyers should file the certificate alongside any temperature log from receiving so the two records corroborate each other. A certificate that looks complete on paper is only useful if it matches what actually arrived.
What a certificate of analysis does not tell you
A certificate of analysis is a quality and testing record. It does not state whether a product's intended use at a given clinic qualifies under the HCT/P framework described in 21 CFR 1271.10, and it is not a substitute for a clinic's own regulatory counsel reviewing intended use, minimal manipulation, and homologous use for a specific application.
It also will not and should not contain clinical claims. A certificate that reports cell biology or particle characterization data is reporting analytical findings, not statements about what a product does for a patient. A document that includes claims about what a product treats or accomplishes clinically is one worth questioning rather than filing.
These products are not FDA approved or licensed for any disease or condition. Information is for licensed healthcare professionals and is not medical or legal advice.
Questions to ask when a certificate is incomplete
Not every document labeled a certificate of analysis contains the same fields. Before placing a recurring order, a buyer should confirm the supplier can produce lot-specific certificates on demand, not a single generic document reused across lots.
Building this check into a standing vendor relationship, rather than a one-time review, keeps documentation current as lots turn over.
- Does the certificate carry a unique lot number matching the shipment
- Is donor eligibility screening referenced or available separately
- Is a named third-party laboratory identified for testing
- Does the document show quarantine and release rather than just a test value
- Can the supplier produce the certificate for a specific lot before the order ships, not only after a question is raised
Frequently asked questions
Does a certificate of analysis mean a product is FDA approved?+
No. A certificate of analysis documents lot-specific testing and release criteria. It does not indicate FDA approval, clearance, or licensure. PB's products are not FDA approved or licensed for any disease or condition; request regulatory documentation for any other supplier's product you are evaluating.
Who at a clinic should review the certificate before an order is accepted?+
If applicable to your practice, have the staff member responsible for inventory and compliance review the document against a standard checklist. Questions about intended use and regulatory classification should go to the clinic's own counsel.
How often should a clinic request an updated certificate?+
A new certificate should accompany every lot. Reordering the same product does not guarantee the same lot, so each shipment should have its own matching document on file.
What should a clinic do if a supplier cannot provide lot-specific documentation?+
Treat it as a vendor qualification gap. A supplier that cannot produce a certificate tied to the lot in hand is a reasonable basis to pause ordering until documentation is available.
