To measure CBD’s quality and the compounds within them, lab tests are performed to distinguish and quantify each CBD hemp extract batch. This is where amounts of THC are measured.
Reputable CBD companies should readily provide third-party lab results, called a Certificate of Analysis (CoA), for their online CBD products or in-store CBD products they carry. When you are looking for the amount of THC on a lab report for a specific product, it is essential to look at the following on the lab report:
1) Limit of Detection (LOD): The LOD shows the other components like additional cannabinoids, minerals, terpenes, pesticides, etc. in the sample being testing. It shows the lowest concentration of each element that can be detected from the selection being measured. In this case, THC.
2) Limit of Quantitation (LOQ): This is the lowest level that can be accurately quantitated (or counted) for each compound that's reported.
With any CBD product you purchase, it is important to dig into the Certificate of Analysis to look at the THC LoQ. If it says "N/D" or "Non-Detect" rather than a number, there are no quantifiable amounts of THC in the product.
