How to Read a CBD Lab Report (COA)

A COA (Certificate of Analysis) is an independent laboratory’s report on one batch. It is the only way to check that the label tells the truth.

1.First: is it your batch

The most important check is the dullest one. The batch number on the report must match the packaging, and the test date should sit close to the production date. A report "for the product in general" proves nothing about the bottle in your hand.

2.The cannabinoid profile

• CBD — the measured amount should match the label within a reasonable tolerance.
• THC and delta-9-THC — below the legal threshold.
• CBDA, CBG, CBN — their presence tells you what kind of extract this is.
• LOQ / ND — "below the limit of quantification" or "not detected".

3.Safety testing

A full analysis does not stop at cannabinoids. Hemp draws from the soil it grows in, so it is also tested for:

• heavy metals — lead, cadmium, mercury, arsenic;
• pesticide residues;
• residual solvents from extraction;
• microbiology and mycotoxins.
