Medical Monday | CBD: The importance of Lab Tests


We are all entitled to know what we consume and should be able to make an informed decision on what enters our body. However, it is not always so easy to judge when it comes to CBD products. It’s important to understand the potency of the product, its Cannabinoid profile and any possible contaminants if you want to maintain consistent high standards of production.


Accurate testing of the product is essential to ensure products have the highest levels of quality, potency and purity. Measuring CBD levels using state of the art High Performance Liquid Chromatography (HPLC) equipment. In addition to testing CBD levels in every batch of oils produced, one should run a full terpene profile and test for microbiological contamination, heavy metals and pesticides.

Testing method for the six main Cannabinoids using state of the art High Performance Liquid Chromatography (HPLC to separate, identify, and quantify each component, or cannabinoid at low levels (parts/million).


Testing for Potency to ascertain the exact amount of Cannabinoids in the product.  CBD is not the only Cannabinoid in cannabis, there are over 600 known Cannabinoids in the cannabis plant and a lab test is essential to confirm the level of Cannabinoids to determine the potency and confirm the lawfulness of the products

Ideally test for CBD, CBDA CBC, THC, THCA CBG and CBN.

Primarily a high potency CBD product is what one looks for, but it’s also essential to have small amounts of the other Cannabinoids as it is the synergistic quality also known as the entourage effect of these compounds that makes it truly effective.


Testing for terpenes to identify the compounds that produce the colour and distinctive flavours to the final product. Terpenes are considered to have many beneficial effects as well.


Testing for pesticides is important to analyse and assure oneself of the safety and purity of the cannabis. If the plant has been treated with pesticides a final product containing a significant concentration of these could cause unwanted side effects. Buy as organically as possible!


Testing for bacteria or mould on the plant material is also primordial to ensure there are no harmful pathogens which could be consumed and cause unwanted side effects.


A complete lab test should also include analyses of residual solvents. Solvents can be used for extraction of CBD when the plant material is turned into oil. High concentrations of solvents can lead to unpleasant health effects and or result in an unsafe product that could be volatile.
