What a Eurofins COA Means for Your Exosome Material
Independent third-party testing from a CLIA-certified lab — the documentation standard every clinic should demand.
Eurofins is one of the world's largest independent laboratory networks, with CLIA certification and ISO 17025 accreditation. When a Eurofins COA ships with your exosome material, it means an unbiased, accredited third party has tested that specific batch — not the manufacturer's own quality control department.
What Eurofins Tests
For B&H Bio exosome material, every Eurofins COA covers three critical parameters:
- Sterility (USP <71>): 14-day incubation confirming absence of microbial contamination
- Endotoxin (USP <85>): Quantitative result in EU/mL — B&H Bio material tests at <5 EU/mL
- Identity: Confirmation the material matches its specification
Why Independent Testing Matters
In-house COAs are standard across the exosome industry, but they create a structural conflict: the same organization that benefits from passing a batch is also the one testing it. An independent Eurofins COA removes that conflict. If a batch fails sterility or exceeds endotoxin limits, Eurofins reports that result — and the supplier can't talk them into changing it.
The B&H Bio Standard
B&H Bio is the only US wholesale exosome supplier shipping every batch with an independent Eurofins Certificate of Analysis as standard documentation — available for review before purchase. One of our competitors uses dual-lab in-house testing. Others use manufacturer-issued COAs. None provide a CLIA-certified, independent third-party COA on every batch.
