Overview
Cannabinoid potency testing measures the strength and composition of finished products. ACT is able to identify and quantify potency content for 16 cannabinoids.

Value
Proper dosing is vital to any patient treatment plan. Therefore, test reliability, ensuring accuracy in product labeling and formulation, is a critical component of patient care.

Overview
Act Laboratories can identify and quantitate 38 terpenes in the cannabis flower and concentrate products.

Value
The combination of cannabinoid and terpene profiles can contribute to the entourage effect. A terpene breakdown can serve as useful to patients looking to identify additional products with similar profiles and psychological responses.

Method
Headspace Gas Chromatography with Flame Ionization Detection (HS-GC-FID)

Overview
Our method confirms the presence of microbial organisms is below the allowable limit of colony-forming units per gram (cfu/g). The scope of testing available varies depending on the regulatory requirements of the state.

Value
Microbial screening ensures organisms’ presence is below a threshold considered safe for consumption.

Overview
Our method confirms the presence of toxins is below the allowable limits of micrograms per kilogram of material. The scope of testing available varies depending on the regulatory requirements of the state.

Value
Mycotoxins are toxic secondary metabolites produced by fungi. Mycotoxin screening ensures toxins presence is below a threshold considered safe for consumption.

High-Performance Liquid Chromatography-Mass Spectrometry (HPLC-MS-MS) ELISA

Overview
Our method determines the presence and contamination of heavy metals are below the allowable limits of micrograms. We can detect metals as low as 0.0375 parts per million (ppm) in the sample. The scope of testing available varies depending on the regulatory requirements of the state.

Value
Heavy metals can be found in soil and water supply. Cannabis is prone to absorbing heavy metals, a.k.a. Phytoremediation, and can cause metals to bioaccumulate in the plant structure. Heavy metals screening helps to ensure metal presence is below limits considered for safe consumption.

Method
High-Performance Liquid Chromatography-Mass Spectrometry (HPLC-MS-MS) ELISA

Overview
Our method determines the presence and amount of residual solvent remaining in concentrates is below the allowable limit in milligrams. The scope of testing available varies depending on the regulatory requirements of the state.

Value
Trace amounts of solvents can be present in concentrates from the extraction process. High concentrations of certain solvents can be harmful if consumed. Screening formulated products for residual solvents help ensure solvent presence is below a threshold considered safe for consumption.

Overview
Act Laboratories performs pesticide residue testing in accordance with the regulatory requirements of each state within which it is licensed. Platforms and methods were developed and tailored to the requirements of each state program in order to exceed specific minimum detection limits established for recognized hazards.

Value
Screening products for these substances help to ensure products are safe for consumption.

Overview
Vitamin E acetate is an additive that can be found in some vape products. The availability of this test varies per state.

Value
Recent investigations by the CDC and FDA have linked vitamin E acetate to thousands of lung injury cases across the United States. Screening vape products for Vitamin E Acetate helps to ensure products are safe for consumption.

Overview
The moisture content is a measurement of all water present within a sample, whether it is bioavailable or not.

Value
Recommended moisture content is between 9-12% (target percentage may vary based on state regulations).

Overview
Water activity is a measurement of bioavailable water, which is water that is available outside of the cells of the sample.

Value
Samples should have a water activity (Aw) of less than 0.65, as recommended by the American Herbal Pharmacopoeia. Water activity above 0.65 can support microbial growth.
