LOD/LOQ: Refers to the sensitivity of the test. In this case, the lab could test down to 0.02 micrograms per 0.05 gram.

Findings refer to our results and Limit refers to the California Standard for heavy metals in vape cartridges which are also the strictest limits in the nation. Status simply means if we pass the California Standard or not.
