The reason for the differing terminologies on the Certificate of Analysis is due to each test conducted being separate from the others. Currently, each test is conducted by a different tech at the lab with each operating under different mandated lab standards.
Each test uses terminology (same as ProVerde, Botanacor, Desert Valley, etc.) to state the test results. "Non-detectable" means that the test concluded that the elements searched for were either not present or in such low quantities that it was not detected. This terminology is generally used when the searched for elements have a very small molecular size. "Conforms" means that the test concluded that no potential contaminants were found, at least not in the ranges established by federal and international standards. "Negative" is equally similar in that no such contaminants were found. "Trace" is standard terminology for the identification of materials that are found in amounts below the minimum reporting threshold. For example, CBDA (cannabidiolic acid) is a precursor to CBD. In its natural state, CBD will likely have trace amounts of CBDA accompanying it in a formula through minimal linking of the molecules, aka a "trace" amount is found. Usually, test results do not even record trace amounts in a potency test; however, we wanted all the cannabinoids found in the formula to have a representation on the COA so we went back to the results to report it accordingly.
