Our Testing Methods

In addition to providing a cannabinoid profile detailing potency information, Steadfast Labs also conducts conclusive testing for a wide range of contaminants to protect consumers and provide you with the assurance of product purity and consistency.


Steadfast is a leader in the development and validation of microbial safety testing in cannabis.


Steadfast employs its proprietary method using UPLC and Tandem Mass Spectrometry to assure your cannabis is free of state-banned pesticides.


Terpenes in cannabis do more than provide the aromas and flavors. They are important contributors to the entourage effect.

Residual Solvents

Concentrates that pass Steadfast’s GC-MS residual solvent screen do not contain harmful levels of extraction solvents, such as butane.

Cannabinoid Potency

Steadfast uses HPLC and LC-MS/MS, for the identification and quantification of cannabinoids. Our extraction methodologies are customized to assure the most robust data for your most difficult matrices.

Heavy Metals

We use state-of-the-art, high-throughput ICP-MS to screen for lead, arsenic, mercury, cadmium, nickel, chromium, and copper.
