How to Read a CBD Certificate of Analysis (Lab Report) for a Hemp Extract CBD Product
What is a Certificate of Analysis or “COA”? It’s a fancy term for a lab report for a hemp extract CBD product. Having trouble reading a CBD lab report? Not sure what you should be looking at? Or, for what?
We’ve created a common list of abbreviations found in a CBD lab report, followed by an interactive guide describing each field to help you navigate and learn what’s in your CBD product.
The interactive guide features a sample certificate of analysis for a sample batch of deepCBDs™ FRESH3500 Tincture (3500mg Hemp Extract Full Spectrum CBD Oil). A number is featured by certain fields/section in the lab report. Hover over, or click the displayed number. A popup will appear with a brief description of the field.
Common Abbreviations in a CBD Lab Report
Below Limit of Detection (“B/LOD”). This means the substance or compound tested was present, but the amount detected is below the cut off value detectable by the testing instrument.
Below the Limit of Quantitation (“B/LOQ”). This means the substance or compound was detected, but the value is below what can be accurately reported. If you review the LOQ for a substance or compound and see “B/LOQ”, it means the detected amount is below that indicated number.
Below Threshold. This means the result for the compound or substance is below the acceptable, legally set number.
Limit of Detection (“LOD”). This is the lowest value that the testing instrument is capable of detecting the presence of a substance or compound.
Limit of Quantitation (“LOQ”). Generally, for the laboratory to report a result value, the number must be greater than or equal to the LOQ number listed in each row of the test column for each compound tested.
Not Detected (“N/D”). This is one of the most common abbreviations on a COA. A result showing N/D means the instrument did not detect the presence of the tested substance or compound. Some products labelled or otherwise indicated to be “THC Free”, “0.00% THC” or “0.00 mg THC” may still contain trace amounts of THC that simply were not detected when tested due to the cut off limit (i.e., the LOD) set on the laboratory’s testing instrument.

Simply click or hover over the displayed number by the field and a pop-up box will appear, providing a brief description for the selected field.
You should always have access to the lab report for a CBD product so you can verify its content and safety for use. Unfortunately, some brands have claimed their products contained a certain amount of CBD when, in reality, less or no CBD was present. The Certificate of Analysis is a resourceful tool available to you in this regard.
If your phone’s camera is unable to scan the QR code, try using a QR code reader app instead. Not all phone cameras function the same and QR code reader apps are generally more successful. If neither of these options work, contact customer support.
On a final note, if you can’t access to the CBD lab report, consider shopping elsewhere, from a brand that provides transparency as to whether their products are tested and for what.
