Third-Party Testing: A Deeper Look at the Main Tests

third party testing

Every other day, new cannabis products are hitting the market, but the quality of some of them is poor. The biggest challenge for traders is how to differentiate between the high and the low quality products to order for their stores.

One of the most effective method of determining high-quality hemp products is subjecting them to third party laboratory testing. In this post, we will tell you the four main types of tests that are done in third party laboratories to determine the quality of cannabis products.

Potency Test

A potency test, also known as a cannabinoid profile test, involves checking the cannabinoids present in a hemp product.

This test is used to determine whether the components indicated in the packaging or ads is correct. For example, if the information on the packaging indicates that the product has a specific amount of CBD and is free of THC, the potency test will be able to confirm that.

Good potency test should be able to establish the presence and quantities of the top 15 cannabinoids, including CBD, THCA, Δ-9 THC, CBC, THCV, Δ-8 THC, CBN, and CBDV.

Organic Solvents

One of the common methods of extracting cannabinoids from a hemp product is using organic solvents, such as acetone and ethanol. However, there is a danger of some solvents being left in the cannabis product.

To address the problem, some manufacturers are now adopting more advanced technologies, such as the supercritical CO2 extraction. Therefore, you will only need to test organic solvents if the process of extraction involved using organic solvents.


Another important test done by third-party laboratories is checking for the presence of pesticides. Notably, most cannabis farms use pesticides to help enhance the growth of the crops and reduce the damage caused by insects.

If residues of these pesticides get their way into the human body, they can have severely damaging effects. Here are some common insecticides that are checked in the laboratories.

  • Cyfluthrin: This is a common ingredient used in most insecticides. But if it is present in any cannabis product and gets into the human body, there is a danger of suffering from problems such as severe migraines, vomiting, and Asthma.
  • Daminozide: This is another common ingredient that is found in pesticides, particularly those used in greenhouses. If it gets into the human body, Daminozide can cause cancer.


Bio-contaminants are natural pathogens such as bacterial, molds, and fungi that mainly get into hemp products when still on the farm. However, some of them can still get into the product during processing. If these contaminants get into the cannabis product user, there is a danger of severe allergic reactions.

The selected third party laboratory tests your samples using technologies such as High-liquid Performance Chromatography (HPLC) and Mass Spectronomy (MS) to determine the presence and quantity of different components.

Note that if the tests find bio-contaminants, organic solvents, and heavy metals in quantities higher than the allowed levels, you should not stock them. Instead, go for high-quality products, which are not harmful to your clients.
