Lab Results

Browsing our range of products, you can encounter two different types of CBD hemp oils:

-FULL-SPECTRUM, obtained by the cold-pressing method, also known as “raw”.

-BROAD-SPECTRUM, obtained with supercritical CO2 extraction.

We are proud to have a range of natural oils suitable for everybody needs.

Reading a COA


All sections in a COA are essential, and all CBD products need to have it done to ensure labelling accuracy regarding THC and CBD content.


 The first thing to look at here is the lab name. This a crucial check to be sure the company you are buying from has the test done by an independent laboratory.

In this section, you’ll also find company and product details. Usually, you can see, the customer (i.e. Voice of Nature), product description, condition and batch number. 

The last item you should see is the test method, in most cases, it’s the HPLC-DAD, which stands for high-performance liquid chromatography with a diode-array detector. It’s the most accurate method a laboratory can use to separate, identify, and quantify each product component.



Cannabinoids profile


This is the juiciest point and what most people are interested in, the cannabinoids concentration of the products, particularly CBD. 

First, let’s explain a couple of concepts and terms that you may find across, and we want you to be familiar with:

Analyte: is the tested substance, the cannabinoids.

LOQ (limit of Quantification): the lowest concentration at which the cannabinoid (analyte) can be detected. If you see “<” or “N/A” on the analyte result, it means that there isn’t enough to be detected.

Mg/ml: it shows how much of the cannabinoid you will find per millilitre of the product. If the oil is in a 10 ml container, multiply the amount of mg/ml shown in the COA times 10 to determine how much cannabinoid is in the bottle. 



99.5mg/ml x 10ml container = 995 mg of substance in the container.


 % w/w- Stands for “weight per weigh percentage”. It is the percentage of cannabinoid per product. For example, a 5 %w/w of CBD means that product is of a 5% CBD concentration.

The measurement of uncertainty: it’s a fundamental concept to understand when you read a COA alone, or you compare two different COA results of the same oil.

The measurement of uncertainty is the expected and accepted level of error for the cannabinoids measurement taken; this always happens in any measure and depends on factors such as calibration. 

Why are we telling you about this? 

Because all CBD oils cannabinoids levels found on the COA aren’t exact but very close to what it says on their label. 

Please also note that certain COAs are only for the hemp extract raw material. Test results for the whole product are often not listed because doing so would reveal proprietary information about the product’s formulation.




We hope you enjoyed the reading, and it helped you to have a better understanding of the laboratory certificates.
