How to Read CBD Lab Reports & Certificates (COAs)

Why lab reports matter

Certificates of Analysis (COAs) confirm your CBD product’s contents match what’s advertised. They prove purity, potency and safety.

Sections of a COA explained

Cannabinoid profile

Shows levels of CBD, minor cannabinoids, and THC (must be under UK limits).

Contaminant testing

Includes heavy metals, pesticides, residual solvents, and microbial results.

Batch & product verification

The batch number on the COA should match your bottle or packaging code.

FAQs

What if a product doesn’t show its COA?

Avoid it. Every trustworthy brand provides public COAs per batch.

Can COAs be faked?

Sadly yes. Always check the lab name and verify the report’s authenticity.

Does a longer list of cannabinoids mean better quality?

Not necessarily — quality depends on consistency, purity and verified content, not quantity.
