QUALITY YOU CAN VERIFY
Testing documents can help you understand what was examined, what the results mean, and which product lot the information belongs to.
A Certificate of Analysis is a document that reports testing information for a specific product or lot.
Identity testing helps verify that the material matches the compound named on the label.
Purity testing reports how much of the tested sample matches the identified compound.
Quantity testing helps show whether the amount in the vial is supported by the test results.
A lot number connects a product with the batch information and documentation that belong to it.
Clear information gives you a better foundation for asking questions and making an informed decision.
HOW TO READ A TESTING DOCUMENT
Start by checking that the product name and lot number match what you are reviewing. Look for the testing date, the laboratory, the methods used, and the results reported.
Identity asks, “Is this the named material?” Purity asks, “How much of the tested sample matches it?” Quantity asks, “How much was measured?” These are related questions, but they are not interchangeable.
A testing document does not prove that a product is safe, effective, sterile, or appropriate for personal use unless those specific questions were examined with suitable methods. If something is unclear, ask.
