Certificates of Analysis

A Certificate of Analysis, or COA, is a document issued by an accredited laboratory that includes a full composition of a product. For CBD, a Certificate of Analysis should include a total list of cannabinoids, microbiological levels, terpenes, and possible contaminants such as pesticides, solvent residue or heavy metals.

pHAZE Naturals assures all of our products to be exactly what we claim them to be and will always provide our Certificates of Analysis as proof.

All pHAZE Naturals’ products will list the batch number at the bottom of each of its’ products.  Please use the either the Search form below to enter in your “Batch Number” to view the corresponding Certificate of Analysis.  The table is also sortable by column.

Frequently Asked Questions regarding Certificates of Analysis

Once you open a COA it is easy to get overwhelmed by the terminology and the amount of information. Not to worry, we will explain what each part means.

When there is a measurement of the CBD amount per gram, you need to know the total weight of a product in grams. The weight doesn’t include the packaging. Most products don’t include weight information on their packaging so you may need to check if it is written in COA.

These are terms that are used to describe the smallest concentration of a measurand that can be reliably measured and calculated by an analytical procedure.

LoD is the lowest analyte concentration likely to be reliably distinguished from the LoB and at which detection is achievable. LoD is determined by utilizing both the measured LoB and test replicates of a sample known to accommodate a low concentration of an analyte.

LoB is the highest apparent analyte concentration expected to be located when replicates of a blank sample containing no analyte are tested.

LoQ is the lowest concentration that may be equivalent to the LoD, or it could be at a much higher level. The analyte can not only be reliably identified but it is also possible to define at which level some predefined goals for bias and imprecision are reached.


ND refers to “none detected” while less than 10 cfu/g refers to the bacterial colony count for the sample with cfu standing for “colony forming units”. If the level is not safe, it has to be indicated as such. But the customer wouldn’t see it because it wouldn’t be allowed on the market.
