What Is a Certificate of Analysis?
A lab report, commonly called a Certificate of Analysis (COA), is a document showing the laboratory results for a specific product or batch.
For cannabinoid products, a COA can show measured levels of compounds such as THCA, delta 9 THC, CBD, CBG, CBN and CBC. This gives customers a clearer understanding of what the tested sample contains.
What Does a Cannabis Lab Report Show?
The exact information depends on the laboratory and tests performed, but a cannabinoid lab report commonly includes:
THCA and THC levels
CBD and other cannabinoids
Product or sample identification
Batch or lot number
Testing date
Laboratory information
Some products may also have separate testing for contaminants such as pesticides, heavy metals, residual solvents or microorganisms.
Why Do Lab-Tested Products Have a COA?
A COA provides documented laboratory results instead of relying only on the information printed on a product page or packaging.
For products such as THCA Flowers, THCA Hash, THCA Extracts and CBD products, laboratory analysis can verify the measured cannabinoid profile of the tested sample.
It also makes it easier to compare the stated cannabinoid content with independent test results.
Is a COA the Same for Every Batch?
Not necessarily. Natural cannabinoid products can vary between production batches.
For this reason, the most relevant COA is one connected to the specific product batch being sold. The batch number or sample ID can help identify which product was actually tested.
Does Lab Tested Mean Everything Was Tested?
No. A product described as lab tested may have been tested only for cannabinoid potency.
Testing for pesticides, heavy metals, solvents and other contaminants may require separate analyses. Always check the COA to see exactly which tests were performed.
Conclusion
A Certificate of Analysis provides laboratory data about a specific product or batch and helps customers understand its cannabinoid content.
When checking a lab-tested THCA or CBD product, look for cannabinoid percentages, batch information, testing date and the laboratory that performed the analysis.
