Understanding Third-Party Testing
Third-party testing means a product sample is analyzed by a laboratory that operates independently from the seller or manufacturer. This separation can provide greater transparency and objective documentation about the specific sample and batch tested.
What Independent Testing Can Evaluate
• Identity — Whether the submitted sample matches the stated compound.
• Purity — The percentage of the sample attributed to the primary compound using the stated analytical method.
• Quantity or mass — The amount detected in the submitted sample when quantitative testing is included.
• Specific contaminants — Sterility, endotoxin, heavy-metal, or other contaminant testing only when those analyses were separately requested and reported.
• Batch-specific results — Documentation tied to the particular lot or sample submitted for analysis.
Understanding the Limitations
Laboratory results apply only to the sample received and the tests performed. Third-party testing does not automatically confirm that every unit in a batch is identical, nor does it establish safety, effectiveness, sterility, stability, or suitability for human or veterinary use unless the applicable characteristic was specifically tested and reported.
