Full-Panel Third-Party Lab Testing

Crescent Canna tests all cannabis products for potency, purity, and quality.

Why is full-panel lab testing vital in helping you find a high-quality CBD or THC product?

The U.S. Food and Drug Administration is still developing hemp regulations. Currently, to be legal, hemp products must contain hemp-derived cannabinoids and less than 0.3% Delta-9 THC, the cannabinoid responsible for the psychoactive effects of cannabis.

What is not required, however, is that hemp products undergo full-panel testing for contaminants. Many companies are opaque about the content of their products and publish a bare-minimum potency test without the full-panel testing that can alone ensure quality and purity.

What We Test For

Crescent Canna is a trusted source of high-quality, small-batch-crafted cannabinoid products. All of our cannabis extracts and finished products are submitted to full-panel testing at an independent testing facility.

Cannabinoid Potency and Legality

Our full-panel testing analyzes the concentration of cannabinoids in every product so you can verify that a bottle of our 9,000 mg Max Strength CBD Drops does indeed contain 9,000+ mg CBD or that our Meteor Bites THC Cereal Bars contain 25 mg Delta-9 THC.

All of Crescent Canna’s THC gummies contain the specified amount of cannabinoids.

When a cannabinoid is not present, this fact is typically displayed on the label as “<LOQ,” which means “less than the limit of quantitation.” The limit of quantitation is the minimum level, concentration, or quantity of a compound that can be effectively measured.

Make sure that you’re getting what you pay for. Verify whether the cannabinoid potency matches or exceeds (by up to 10%) what is stated on the label.

Residual Solvents

Solvents are widely used in manufacturing to dissolve or extract other substances. Residual solvents are solvents that are not completely removed after processing and can therefore compromise the quality or safety of a product. Beyond certain levels, they can be harmful.

Solvents are often used to extract compounds like cannabinoids from plants. A full-panel screening will show whether any residual solvents — including acetone, benzene, ethylene, methanol, propane, butane, and many others – remain in the finished product.


Pesticides are poisonous to humans and can cause health problems, including damage to the nervous, reproductive, and immune systems. Pesticides can even disrupt ecosystems if they contaminate the soil or water sources.

All of our CBD and THC products are made from organic, US-grown hemp, and the full-panel testing confirms that they are free of pesticides.

Heavy Metals

Our full-panel screenings also show that our products are free of any heavy metals, including arsenic, cadmium, lead, and mercury.

Heavy metals are often present in the ground either naturally or as the result of industrial and agricultural pollution. If a crop of hemp is contaminated with heavy metals, the metals are likely to show up in products made from the hemp. Like pesticides, heavy metals can be bad for us. Some — mercury, arsenic, and lead — are regarded as especially dangerous.

Microbiological Contaminants

This part of the test detects levels of mold, yeast, and various bacteria. Mycotoxins, Listeria monocytogenes, and pathogenic bacteria each get their own section. Two pathogenic bacteria are listed separately: E. Coli and salmonella.

Mycotoxins. These toxic compounds are naturally produced by certain fungi and can seriously harm your gut health if ingested, even in very low concentrations.

Listeria monocytogenes. Responsible for listeriosis, a rare but deadly disease, Listeria monocytogenes are bacteria that live in soil, water, and dust. An infection may not pose much danger to some people, but it can be life-threatening for others.

Pathogenic bacteria. Although some E. coli bacteria are harmless, others are pathogenic, i.e., disease-causing.

In the sections for residual solvents, pesticides, heavy metals, and contaminants, our certificates of analysis display a clear “pass” designation that is based on EPA or FDA standards. You won’t be seeing any “fails” in certificates for any of our products. Another important abbreviation is ND (“not detected”), which you will see in the Result field for residual solvents and pesticides.

The Crescent Canna Difference

All Crescent Canna products are full-panel tested by an independent ISO17025-accredited laboratory to ensure quality and potency. Visit our testing page to see our most recent certificates of analysis or contact us to ask any questions about our products.
