Frequently Asked Questions
Quick references for what each test means.
Why are endotoxin tests run in duplicate?
USP <85> requires duplicate analysis to rule out measurement error. Both replicates must be below the sensitivity threshold (typically ≤0.05 EU/mL) for the batch to pass. Disagreement between replicates triggers a re-test.
Does "Cleared" mean safe for human use?
No. "Cleared" here means the batch meets the USP <85> endotoxin reporting threshold — a standard relevant to laboratory research materials. All products from Oath Research are strictly for research use only and are not approved for human, veterinary, diagnostic, or therapeutic applications.
Are all my orders from this exact batch?
Not necessarily — batches are rotated as inventory moves. Check the batch code on your vial against the test history above to find the matching certificate. Every batch we sell has been independently tested.
