How to Read a
Kratom COA
A complete guide for Canadian buyers on understanding Certificate of Analysis lab results - alkaloid profiles, heavy metals, microbiological testing, and what to watch out for.
Certificate of Analysis
A COA (Certificate of Analysis) is a laboratory report that provides batch-specific information, including a product's botanical profile and quality screening results. By understanding how to read a COA, buyers can move beyond marketing claims and evaluate objective testing data for themselves.
The most crucial document to request from any Canadian kratom vendor is a COA. Batch-level COAs are the gold standard - they correspond to the specific production lot you are purchasing, not a generic product-line report.
Independent testing by an accredited third-party laboratory is much more credible than vendor in-house testing. The lab has no financial stake in the sale, making their documentation independently verifiable.
How to Read a COA
Most kratom COAs are structured the same way. Here is what each section means and what to look for.
Alkaloid Panel
The first section buyers look at. This table contains major compounds of the botanical material, such as Mitragynine and in some instances 7-Hydroxymitragynine. Pay attention to consistency and documentation rather than assuming higher percentages always mean better quality.
Heavy Metals Screening
This panel screens for Lead, Arsenic, Mercury, and Cadmium. Measured levels and methodology of testing should be clearly indicated in the report. The outcomes must match the batch number mentioned in the document.
Microbiological Testing
Measures the occurrence of particular microorganisms regularly checked in botanical materials. Common screening types include Salmonella, E. coli, Yeast, and Mold. Findings and methods of laboratory analysis should be clearly presented.
Pesticide Screening
Determines the presence of agricultural residues in the sample. Not all laboratories use the same screening panels. Credible reports explicitly reveal the materials tested and the respective outcomes.
Moisture Content
Less focus is usually given to moisture testing, but it is a valuable quality-control indicator. This section quantifies the quantity of moisture in the batch during testing and can provide additional insight into quality-control practices.
Warning Signs on a Kratom Lab Report
Not all lab reports are equally transparent. Knowing what to look for - and what to be cautious about - helps you make informed purchasing decisions.
What to Ask For
If a COA is not publicly available, request it directly from the vendor. Their response can be a valuable indicator of their commitment to transparency.

COA Questions Answered
A Certificate of Analysis (COA) is a document from a third-party laboratory confirming the alkaloid profile, heavy metal screening results, microbiological testing outcomes, pesticide analysis, and other quality-control information for a specific batch. It serves as a primary verification tool for buyers, allowing you to move beyond marketing claims and evaluate objective testing data for yourself.
- Alkaloid panel (Mitragynine % and 7-Hydroxymitragynine where applicable)
- Heavy metals screening (Lead, Arsenic, Mercury, Cadmium)
- Microbiological testing (Salmonella, E. coli, Yeast, Mold)
- Pesticide residue analysis
- Moisture content
- Batch identification number and testing dates
The alkaloid section displays the percentage of key alkaloids within the tested batch. These figures describe alkaloid composition and consistency rather than overall product quality by themselves. When reviewing a Mitragynine percentage, focus on consistency and documentation rather than assuming higher numbers automatically mean better quality.
Industry best practice favors current batch-level testing. Reports older than six months should be reviewed carefully, especially if they do not correspond to a specific production batch. Older COAs may not reflect the product currently being sold.
Some vendors conduct internal testing using their own equipment. Although this can be useful, it is still produced by the company that sells the product, so consumers cannot independently verify those results.
Third-party testing sends samples to an external accredited laboratory that has no financial stake in the sale. Since the testing organization is independent, the documentation produced is generally more credible and trustworthy.
A common misconception is that a single COA can represent all packages sold under a product name. In reality, botanical materials can vary from batch to batch due to sourcing, harvesting conditions, processing, and storage.
A product-line report may only reflect a single sample tested months or years ago. In comparison, lot-specific documentation allows buyers to confirm the exact batch they are purchasing. Batch-level testing is the gold standard of quality transparency.
Yes. Reputable Canadian vendors should be able to provide a current COA upon request. Delays or an inability to produce documentation may warrant further investigation. When requesting a COA, ask for: the most recent batch-specific COA, the laboratory name and accreditation details, the testing date, and the matching batch number.
