However, how it appears on the outside has no relation to how the product tested. This is where the laboratory test report, also known as a Certificate of Analysis (COA), can provide you with some insight into the quality of the product. While the COA provides some valuable information, most users will find themselves confused by the numerous abbreviations used, unit conversions, and chemical names. So here is an example of what to check first. ## **1. Make Sure the Report Matches the Product** Review what information was provided with the Certificate of Analysis (COA) before checking THC content levels. Check to see if the COA corresponds to the product that is in front of you. The COA should have: - product name - brand name - batch/lot # - sample ID# - date tested - description of product Of all items listed above, it would be best to check the batch number as this will tell you if the COA is from a production batch other than the one you are testing. ## **2. Check Who Did the Testing** A proper report should clearly identify the laboratory. Look for: - laboratory name - address or contact details - certificate or report number - test dates - signature or approval details - QR code or verification link A screenshot saying **“Lab Tested”** is not the same as a full COA. You should be able to identify who tested the sample and when. ## **3. Understand the Cannabinoid Panel** This is usually the section people check first. You may see: - Δ9-THC - THCA - CBD - CBG - CBN - CBC - Total THC Results may be shown as: - % - mg/g - mg/mL - mg per unit Always check the unit. For example, **850 mg/g** is not the same as **850 mg per cartridge**. A big number means very little if you do not know what it measures. ## **4. Do Not Judge Quality by THC Alone** Simply because a cartridge shows 92% THC does NOT mean that it is superior to a cartridge with 78% THC. That fact alone will not provide information on: - contaminants in the product; - the flavor; - hardware performance; - terpene balance; - your actual batch. There are many aspects of cannabis products that include but do not stop at THC levels. ## **5. Check the Terpene Profile** Some COAs also include terpene testing. Common names include: - myrcene - limonene - beta-caryophyllene - linalool - pinene - terpinolene You do not need to memorise them all. Simply check which terpenes are present, which are dominant, and whether the profile makes sense for the product description. ## **6. Look for Residual Solvent Testing** Extracted products may be tested for residual solvents such as: - butane - propane - ethanol - methanol - acetone - benzene - hexane Do not panic just because a chemical name appears on the report. Labs often list every substance included in the test panel. What matters is the result beside it. You may see: - **ND** - **Not Detected** - **
