How to use the checklist
Find the lab report for the batch you're buying, not a generic sample report. Work through the four groups and treat each unchecked item as a question for the vendor. For a field-by-field walkthrough, read how to read a kratom lab report.

Frequently asked questions
What should a kratom lab report include?
The product and batch number, the test date, a named lab, alkaloid content, heavy metals (lead, arsenic, cadmium, mercury), and microbial tests for salmonella, E. coli, yeast and mold.
How do I know a kratom COA is real?
Confirm it with the lab that issued it, through its portal, a QR code or by email. A report you can't trace to a named lab can't be verified.
Why check 7-OH on a lab report?
Plain leaf has only trace 7-OH. A result well above natural levels suggests an enhanced product, which we don't list.
