What are the differences between testing for regulatory compliance vs. research and development (R&D) or quality assurance/quality control (QA/QC)?
Cannabis compliance tests:
- Designed to meet the regulatory requirements for cannabis products as required by various governing bodies.
- Must be reported to individual states’ track-and-trace systems, like Metrc, where they may be used to validate or disqualify batches as eligible for market.
- In some states, cannabis sampling is required to be performed by laboratory personnel or designated test batch collectors (requirements vary by state).
Hemp compliance tests:
- Intended to meet the regulatory requirements for industrial hemp and hemp products as required by various governing bodies.
- Pre-harvest tests must be reported to the Department of Agriculture, where they may be used to validate or disqualify batches as eligible for market.
R&D or QA/QC tests:
- Limited to internal use by producers, manufacturers, distributors, patients, etc.* to verify or improve the quality of their products/processes.
- Are not reported to the state, and are not associated with batches.
- Require a smaller sample size.
- Allow clients to choose any combination of tests à la carte—including tests under the compliance panel and additional specialty tests.
- Do not require SC Labs to perform the sampling.
- R&D samples can come from non-licensees, while QA/QC samples must come from a licensee.
Both regulatory compliance and R&D testing rules vary by state, so please speak with your account manager for more information.
Yes! SC Labs’ professional field technicians can make sampling an efficient and enjoyable part of your process. Contact your account representative to schedule sampling or pickup service.
We offer sampling and/or courier services for hemp samples in the following states: Arizona, California, Colorado, Michigan, and Oregon. Those in other states or countries are welcome to ship samples. Please contact your account representative for more information about which laboratory to send samples to.
Samples may be dropped off at our Scottsdale lab Monday through Friday from 8 a.m. to 5 p.m. Walk-ins are welcome. We accept samples from all Arizona dispensaries and product manufacturers, as well as medical and adult-use consumers.
While our AZ lab does not perform the sampling itself, we do offer free sample pickup for Chronic Customers and customers within 25 miles of our Scottsdale location, with a minimum order of $500. Pickup service is also available outside of that radius for an additional fee.
Under California’s cannabis regulations, all regulatory compliance test samples in California must be taken by an employee of the testing laboratory using validated methods to ensure that the sample is representative of the larger batch. The collection of compliance samples must occur at a distributor’s or microbusiness’ licensed facility under camera surveillance.
All QA/QC or R&D test samples for cannabis (not hemp) submitted by licensees must either be collected from the licensee’s premises by the lab sampler/courier, or be delivered to the licensed lab facility by an employee of the licensee.
We also have couriers throughout California available to pick up non-regulated samples. We are able to accept samples via certain third-party couriers as well. Your account representative will help you find the most efficient method of getting your samples to the lab.
In Colorado, cannabis samples must be collected from the licensee’s premises by a Designated Test Batch Collector or a licensed lab sampler.
We offer fast sample pick-up all across Colorado, with regular service along the Front Range (Fort Collins, Boulder, Denver, Colorado Springs, and Pueblo). Please contact us to arrange collections outside this area.
Under current Michigan regulations, all samples must be collected from the licensee’s premises by a licensed lab sampler.
We offer a vast network of trained samplers spanning across Michigan, and we’ll work with you to find a convenient day and time to perform the sampling event.
In Oregon, an agent of the testing laboratory must perform the sampling for regulatory compliance tests, although the producer may bring the batch to the laboratory for sampling.
Contact us for information on submitting R&D samples. Your account representative will help you find the most efficient method of getting your samples to the lab.
We have changed how we schedule our sample intake to provide our customers with a more reliable turnaround time. For all standard tests, with the exception of a few microbial tests that require a longer incubation period, SC Labs averages a three-day turnaround time. We will send you a notification when your results are ready with a link to our Client Services Portal, your one-stop shop for ordering* and reporting.
*Ordering through the CSP is only currently available in California.
Customers who want to use the SC Labs “Tested” logo on their products must perform and pass full regulatory compliance testing for each batch of product that is bearing the logo. There are no exceptions. Please contact your account representative for more information.
The use of either the SC Labs “Tested” logo or the SC Labs logo without express written permission from SC Labs is strictly prohibited. SC Labs makes every effort to ensure that clients whose products bear an SC Labs logo adhere to our rules and protocols, but hold no warranties or guarantees on any product bearing our logo nor any representations by the manufacturer thereof.
We always recommend that cannabis consumers request a Certificate of Analysis from the manufacturer, distributor or retailer to ensure that the product has been tested for safety.
We test cannabis and hemp flowers, concentrates/extracts, leaves, e-liquids/vape oils, crystallized isolates, as well as liquid and solid infused products such as lotions, tinctures, and edibles. Don’t forget about your inputs! We test beeswax, rolling papers, chocolate, terpenes, and much more. If you need a product tested that does not fall within this list, contact us, it is likely that we can test that too!
SC Labs offers safety and potency testing that satisfies cannabis regulatory requirements in Arizona, California, Colorado, Michigan, and Oregon as well as hemp regulatory requirements nationwide.
As just an example, our menu of testing services includes profile testing for cannabinoids and terpenes; contaminant testing for heavy metals and microbials; and speciality testing for shelf life and Vitamin E.
See the full list of testing options below:
It depends. While we can only test homegrown or unlicensed cannabis in Arizona, California, Michigan, and Oregon, we can test homegrown/unlicensed hemp from anywhere inside and outside the USA.
We can accept hemp samples from outside the United States, but all foreign samples must include the proper import paperwork. Please contact us for more information.
It depends on what you need and where you’re located. Within our network, we test Δ8, Δ9, Δ10, and exo-THC.
The number of terpenes on our tests varies by state. We currently test for the 39 most common terpenoids in California, 22 in Colorado, 20 in Michigan, 35 in Oregon, and 21 in Arizona.
In 2021, we introduced a revolutionary chemometric report, Phytofacts®, that utilizes the sample’s cannabinoid and terpenoid data to offer insight into its chemometric profile, flavors, aromas, anticipated effects, and more.

At this point, your samples will appear in the TagLeaf portal; a notification email will be sent to you when the samples have been published.
To schedule a pick up, you can reach out to your Oregon Account Manager by phone or email. Orders are submitted in Metrc after sampling. Once placed, you will be able to track your order within the CSP.
Existing Arizona clients can request a pickup through the Confident Cannabis portal.
Samples dropped off between 8 a.m. – 5 p.m. will be entered into the system that same day, which is Day Zero. If you place an order for pickup before 8 a.m. on a business day, we will pick it up same day. If you place the order after 8 a.m., we will pick it up next business day. For pickups outside of metro Phoenix, please call the lab to arrange a day for pickup.
We are unable to receive cannabis samples via mail. All cannabis samples for regulatory compliance and R&D testing must be transferred into our custody following your state-specific requirements. In California, for instance, cannabis compliance samples must be sampled at your facility by an SC Labs field technician, while R&D cannabis is allowed to be delivered to the lab by an employee of the distributor or microbusiness. In Colorado, compliance sampling can be handled by a Designated Test Batch Collector, and clients can drop off R&D samples to the lab so long as it’s logged and transferred to us in Metrc.
We do accept Hemp (below 0.3 % Δ9-THC post-decarboxylation as defined by the 2018 Farm Bill) samples via the mail.
Both regulatory compliance and R&D testing rules vary by state and by hemp vs. cannabis, so please speak with your customer service representative for more information.
In accordance with SC Labs’ Testing Agreements and to ensure transparency within the cannabis marketplace, all passing compliance and R&D (QA/QC) test results are initially set to “Public.” This aids consumers and supply-chain business partners when verifying results.

For additional assistance, any one of our SC Labs account managers are happy to help you understand your results.
Cannabis regulations vary greatly depending on where you are, and they change often. For the latest regulations, please check the websites of your regulatory bodies.
Arizona regulates cannabis and cannabis products through the Arizona Department of Health Services (ADHS), which requires third-party laboratory testing.
Arizona compliance testing regulations require different tests depending on the type of product. These tests include potency, pesticides, residual solvents, heavy metals, mycotoxins, E. coli, Salmonella, and Aspergillus.
Sampling does not have to be performed by lab staff or a state-certified sampler.
Since passage of the first regulations with the Bureau of Cannabis Control (now the Department of Cannabis Control) in 2018, the State of California has required safety and dosage testing of both recreational and medical cannabis and cannabis products.
To be compliant with the California Department of Cannabis Control (DCC) testing requirements, a producer needs to test each batch for cannabinoid levels, residual solvents and processing chemicals (cannabis products and pre-rolls only), residual pesticides, microbial impurities, moisture content (flower and pre-rolls only), foreign material, mycotoxins, heavy metals, and water activity (flower, pre-rolls, and solid edibles only). Terpenoids are a required test when producers make label claims involving terpene content.
Current regulations require laboratory personnel to perform representative sampling for all regulatory compliance testing. SC Labs has an experienced team of samplers and we offer an extensive sampling program. We can meet your sampling needs where you need us, when you need us!
Colorado regulates cannabis and cannabis products through the Marijuana Enforcement Division (MED), which requires third-party laboratory testing. Sampling procedures are regulated by the Colorado Department of Public Health and Environment (CDPHE).
Colorado compliance testing regulations require different tests depending on the type of product. These tests include potency, homogeneity, elemental impurities (heavy metals), microbiological contaminants, mycotoxins, pesticides, residual solvents, and water activity.
Sampling must be conducted at a licensee’s premises by a Designated Test Batch Collector.
In Michigan, the Cannabis Regulatory Agency (CRA) establishes the regulatory testing requirements for cannabis and cannabis products, including the laboratory-performed collection of a cannabis batch. Compliance tests might include potency, pesticides, residual solvents, heavy metals, microbiological impurities, homogeneity, water activity, foreign matter, and vitamin E, depending on the product type. Batch sizes also depend on the product type.
If you need any assistance parsing the regulations listed below, please contact your local SC Labs account manager. They are available to support both your scientific and regulatory needs.
Oregon requires defined sets of compliance tests that vary depending upon the type and intent of the product. Product ‘types’ include usable marijuana (cannabis buds, shake, or trim), extracts/concentrates, kief, cannabinoid products, and finished inhalables. The ‘intentions’ include retail sale, further processing into a product, and further processing into a concentrate, extract, or finished inhalable.
The Oregon Health Authority has provided a Cannabis Testing Guide (pdf) to detail the tests required for any combination of product type and intention.
Oregon regulations require independent representative sampling. SC Labs can arrange for sampling anywhere in Oregon to meet your testing needs. Please contact your customer service representative to schedule sampling.
More information on Oregon’s marijuana testing regulations can be found at the Oregon Health Authority website.
The Limit of Detection (LOD) is the lowest concentration of an analyte (the compound you are testing for) that the laboratory can confidently say results in a positive detection. In other words, it is the lowest concentration of an analyte where the response on the instrument can be confidently distinguished from baseline noise.
The Limit of Quantitation (LOQ) is the lowest concentration of an analyte that can be reliably measured by a laboratory. In other words, it represents the lowest point in the laboratory’s range of quantitation for that analyte. In order for a laboratory to accurately quantify results, the LOQ must be within the range of an instrument’s calibration.
A laboratory with lower LOD and LOQ is typically capable of a more sensitive analysis. The LOD* and LOQ for each analyte tested is recorded on all of our COAs. When the concentration of an analyte is determined to be between the established LOD and LOQ, the result will be reported as “< LOQ”.
* LOD is not included on COAs in our AZ laboratory.
The Sum of Cannabinoids is the concentration of each individual cannabinoid tested added together as they are. It does not account for decarboxylation and is representative of the chemical profile of the sample before being heated/smoked. Since certain cannabis products are not intended to be smoked, this uncorrected data is of particular importance to both producers and consumers of those types of products. As an example, our Santa Cruz, CA laboratory calculates Sum of Cannabinoids with the following formula:*
The Total Cannabinoids is the concentration of each acidic cannabinoid, multiplied by 0.877 to account for the loss of the carboxyl group, then added to the concentration of the neutral cannabinoid for a total. Accounting for the decarboxylation of THCa and CBDa in this manner is required by DCC regulations, however, SC Lab has chosen to apply this logic to all acidic cannabinoids. This corrected data is of particular importance to both producers and consumers of products intended to be smoked. It is calculated according to the following formula:
* The above calculations may vary based upon the lab location, as some state requirements and lab offerings will include varying sets of cannabinoids.
Measurement Uncertainty is the range of possible values surrounding the measurement value. The size of this range determines the confidence of measurement, or how accurately the measured value compares to the true value.
We determine Measurement Uncertainty for all of our analytes in accordance with Joint Committee for Guides in Metrology (JCGM) Guide to the Expression of Uncertainty in Measurement (JCGM 100:2008 – GUM 1995 with minor corrections), as required by ISO 17025:2017. This internationally recognized standard requires us to conduct numerous experiments in order to determine the uncertainty of our test methods and equipment utilized when analyzing a given analyte in a particular matrix.
Moisture Content is a measure of the quantity of water and other volatile compounds in a material.
Water Activity is a little more complex in concept and is more a measure of the ‘availability’ of that water to support microbial growth. For example, foods with a lot of sugar or salt, like honey or bacon, will often have a comparatively lower water activity despite a higher overall moisture content, and they will resist spoiling compared to other foods with similar moisture contents.
The way SC Labs measures Moisture Content is by weighing a material before and after drying to a constant mass. This ‘loss on drying‘ can be expressed in multiple formats, typically either as a ratio or a percentage representing the portion of the solid sample’s weight that was moisture. SC Labs, like other cannabis laboratories, uses ‘loss on drying’ to measure cannabis samples and records results as a percentage.
Water Activity is defined as the partial vapor pressure of water in a material (cannabis, food, etc.), divided by the partial vapor pressure of water at the same temperature. Increased Water Activity values are indicators of increased likelihood of microbiological growth. Water Activity is expressed in units of aw and values of over 0.7aw are generally considered to support fungal growth while bacteria tend to proliferate at above 0.9aw. Besides an indication of likeliness to support microbiological growth, water activity gives an indication of the long-term stability—or shelf life—of cannabis and its products.
Why is Moisture Content automatically conducted for QA/QC cannabinoid testing submissions in California?
The California Department of Cannabis Control (DCC) strictly requires that all cannabinoid data for compliance flower and un-infused pre-roll samples be reported on a dry-weight basis; therefore, all cannabinoid concentrations must be adjusted to account for a flower’s moisture content. In an effort to better reflect the cannabinoid results of compliance testing during R&D testing, our California labs automatically conduct moisture testing on all flower and un-infused pre-roll sample submissions. It is calculated according to the following formula:
SC Labs uses quantitative polymerase chain reaction (qPCR) for Microbiological Contaminant testing. qPCR is a highly sensitive and discriminatory technique for identifying and quantifying microorganisms. It directly detects and measures DNA of only the specific species of organisms we are looking for. When properly developed, the high selectivity of qPCR greatly reduces the possibility of false positives compared to other techniques. We have painstakingly selected, developed, and validated, what we believe to be the most reliable selection of microbiological contaminant assays available to the cannabis market.
View our test menus to find out more:
We also offer testing for microbiological contaminants using 3M™ Petrifilm™. Current tests include yeast and mold, aerobic bacteria, E. coli, Coliforms, Salmonella, and more.
“Mycotoxin” is an umbrella term used to define toxic compounds produced as secondary metabolites by fungus. There are several types of mycotoxins produced by a wide variety of fungi. Some of the most prolific producers of mycotoxins are some Aspergillus species of fungi, but other common cannabis contaminants like certain species of Fusarium and Penicillium are known producers of mycotoxins. Some mycotoxins that could be of concern to cannabis consumers include aflatoxins (B1, B2, G1, G2), ochratoxin, citrinin, and fumonisins.
SC Labs is proud to have achieved ISO 17025:2017 accreditation for its labs in Arizona, California, Colorado, and Michigan. The International Organization for Standardization (ISO) is the recognized leader in developing international standards for testing labs, manufactured products, agricultural and food safety, consumer products, and healthcare. The ISO 17025 accreditation standard applies directly to testing laboratories including environmental, food, and, now, cannabis laboratories. It prescribes documentation and transparency requirements into most functions of a laboratory, especially quality management systems, test method validation, and customer transparency.
SC Labs considered ISO 17025 accreditation vital to ensuring customer confidence in our test results and quality management systems. That’s why we attained our accreditation before it was a requirement. Our customers enjoy peace of mind that their test results from SC Labs will stand up to scrutiny from any regulatory or other third-party entity.
- When referring to cultivated medical marijuana, a specific lot of medical marijuana grown from one or more seeds or cuttings that are planted and harvested at the same time.
- When referring to marijuana products, a specific amount of a marijuana product infused, manufactured, or prepared for sale from the same set of ingredients at the same time.
- When referring to testing of medical marijuana or a marijuana product, a specific set of samples prepared and tested during the same run using the same equipment.
Current Department of Cannabis Control regulations specify the maximum weight of a harvest batch of cannabis flower is 50 lbs. A batch of cannabis products can contain no more than 150,000 units. As such the DCC requires one regulatory compliant test panel per 50 lbs. of cannabis flower or 150,000 units of a cannabis product at a minimum. Learn more.
Current MED regulations do not stipulate a maximum batch weight. In order to run full compliance tests in Colorado, we require the following minimum sample sizes: Flower 17 g; Concentrate 6 g; Viscous Extracts 10 g; Infused Product 16 g; and Vape Carts 18 g. Learn more.
Current Cannabis Reulatory Agency (CRA) regulations specify that a maximum batch size of flower is 50 lbs. We always require at least 14 g of material to run full compliance tests in Michigan, even if your calculated minimum sample size is lower. Learn more.
A batch of Usable Marijuana cannot exceed 50 lbs, in containers no larger than 15 lbs. Manufactured products including: concentrates, extracts and other cannabis products batch sizes are limited to the size of the manufacturer’s production run. Learn more.
Sample size requirements may vary depending on state requirements, laboratory requirements and your product type. Be sure to speak with your SC Labs account manager to ensure successful sample submission. To ensure your data is as accurate, compliant, and defensible, please refer to the following guidance.
