Why Batch Matching Matters
Use the Lab Results page to locate available third-party reports. Match the product and batch or lot identifier before relying on a report, then review the analytes, methods, dates, and reported results within that document.
What to Review in a Report
Review which analytes were included, the reported methods and dates, product and batch or lot identifiers, and the values shown in the report. A report should not be treated as covering products or batches it does not identify.
