# How do I Update Information on a Report or Certificate of Analysis that was Issued?

## Need to correct a sample name, details, or other information on your report?

Sometimes the information on a report needs to change. A product name was entered differently, a batch number has a typo, or your company address changed after the sample was submitted.

All report changes go through your laboratory and they are the only ones who can make a change and reissue a corrected report. We recommend getting in touch with your lab directly to request any updates to reports or Certificates of Analysis.

#### **How to Contact your Laboratory**

- **Email or phone.** Your lab's contact details typically appear on your report and in your Client Portal.
- **Your lab's account or sales representative,** if you work with one directly.
- **Your lab's own support channel,** such as a ticket form or help desk, if they have one available.
