How to Read Lab Test Results for Our Cannabis Products
A cannabis product’s label tells you what it is meant to contain, while a laboratory report shows what an independent testing process found in a specific batch. Learning to read that report can help you compare potency, understand cannabinoid and terpene content, and identify important safety results before purchasing Persy Diamonds, rosin, infused flower, cartridges, or pre-rolls.
At Persy Diamonds Store, product information should be considered alongside the applicable certificate of analysis, often called a COA. A COA is tied to a batch or lot number, so the most useful report is one that matches the exact package you are considering rather than a general report for the product line.
Lab results are technical documents, but the main sections are easy to recognize once you know what they mean. The key is to read beyond the largest THC number and check the sample identity, testing date, units, contaminants, and whether the report covers the product in its final form.
Start with the product and batch details
The first part of a certificate of analysis usually identifies the product, client, sample type, batch number, and date the laboratory received or tested the sample. Compare those details with the packaging. A mismatch may mean that the report belongs to a different production run, flavor, strain, or product format.
This check is especially important for concentrates. Persy Diamonds, Snowcaps, Snowballs, Slabs, and rosin can have similar naming conventions while differing in cannabinoid concentration, terpene profile, or batch composition. A report for one item should not automatically be used to describe another.
Look for the laboratory’s name, license or accreditation information, report number, and finalization date. A professional COA should clearly identify the testing facility and present results in a way that can be traced back to the sample. If a QR code is printed on the package, scan it and confirm that the linked report shows the same batch information.
Authenticity and lab testing answer related but different questions. A valid-looking report does not replace packaging checks, seller verification, and brand-specific details, so review this authenticity guide when assessing Persy by 710 Labs products.
Understand cannabinoids and potency numbers
The cannabinoid section commonly lists THC, THCA, CBD, CBDA, CBG, CBC, or other compounds detected in the sample. The result may appear as a percentage by weight, milligrams per gram, or total milligrams per package. These formats are related but should not be treated as interchangeable without checking the serving size and product weight.
For example, 1% by weight equals approximately 10 milligrams per gram. A 75% concentrate therefore contains roughly 750 milligrams of total cannabinoid content per gram, before considering the difference between reported THC and THCA. The package size determines how much total cannabinoid is present.
Raw cannabis contains substantial THCA, which can convert to THC when heated. Many COAs therefore display separate THCA and THC values, along with a calculated “total THC” figure. The exact calculation can vary by jurisdiction or laboratory convention, so use the total value shown on the report and follow the label’s serving guidance rather than doing an independent calculation.
Potency is useful for comparing products, but it does not predict the complete experience. A high-potency concentrate may require a much smaller amount than infused flower or a pre-roll. New or infrequent consumers should pay close attention to serving information and local legal guidance.
Read the terpene profile as a quality detail
Terpenes are aromatic compounds that contribute to the scent and flavor of cannabis. Common entries include limonene, myrcene, beta-caryophyllene, pinene, linalool, and humulene. A COA may list each terpene as a percentage, milligrams per gram, or a total terpene percentage.
A terpene report can help explain why two products with similar THC levels smell and taste different. For instance, limonene may be associated with citrus notes, while pinene can contribute a pine-like aroma. These descriptions are sensory reference points, not guarantees of a specific effect or medical outcome.
The total terpene value also needs context. Concentrates and rosin often show a different profile from flower because extraction and processing affect volatile compounds. Storage matters as well: heat, light, oxygen, and repeated opening can reduce freshness over time. Follow these storage instructions to help preserve the product’s aroma and texture after purchase.
Check the safety and contaminant panels
A complete cannabis COA generally includes safety testing for pesticides, heavy metals, microbial contamination, mycotoxins, and residual solvents when relevant. The exact panel depends on local regulations and the product type. These sections may use terms such as “pass,” “fail,” “action limit,” “LOQ,” or “ND.”
“ND” commonly means “not detected,” but it does not mean the substance could never be present. It means the tested amount was below the laboratory’s reporting or detection threshold. “Pass” generally indicates that the result met the applicable limit for that test. If a contaminant is listed above an action limit, the batch should not be treated as compliant.
Residual solvent testing is particularly relevant to some extracted products. A result showing no detected solvents or results below permitted limits is different from a report that does not include solvent testing at all. For solventless products such as many forms of rosin, the risk profile and testing requirements may differ, but the COA should still be reviewed for the panels that apply.
Microbial and mycotoxin results are also important for flower and infused products. A report may distinguish between total yeast and mold, pathogenic organisms, and other microbial categories. Read the actual test names and limits rather than assuming that one “clean” result covers every possible contaminant.
Compare what each result means
The following guide summarizes the most common COA fields and how they can help when comparing products. Laboratory terminology varies, so the report’s notes and local testing standards remain the final reference.
| COA field | What it shows | Why it matters |
|---|---|---|
| Batch or lot number | The production run tested | Confirms the report matches the package |
| Total THC | Calculated THC content, often including converted THCA | Helps compare overall potency |
| THCA and THC | Acidic and neutral cannabinoid forms | Explains how cannabinoid content is reported |
| CBD and minor cannabinoids | Detected non-THC compounds | Shows the broader cannabinoid profile |
| Terpenes | Aromatic compounds and their quantities | Helps compare flavor and aroma characteristics |
| Pesticides | Agricultural chemicals screened in the sample | Indicates whether tested compounds met limits |
| Heavy metals | Metals such as lead, arsenic, mercury, or cadmium | Addresses contamination from soil or processing |
| Microbial testing | Yeast, mold, and specified organisms | Helps assess biological contamination |
| Residual solvents | Solvent compounds remaining after extraction | Relevant to certain concentrates and extracts |
| Result status | Pass, fail, ND, or numerical result | Shows how findings compare with regulatory limits |
When comparing two products, use the same units wherever possible. A percentage result for one sample and milligrams per gram for another can still be compared after conversion, but package size and serving size must remain separate considerations. A larger package does not necessarily have greater potency per gram.
Spot limitations in a lab report
A COA represents the tested sample, not an unlimited guarantee about every unit in a batch. Cannabis products can vary naturally, particularly flower and products made from plant material. Testing is intended to provide a documented snapshot under defined laboratory methods.
A report also cannot confirm every quality characteristic. It may not describe texture, flavor, freshness, hardware performance, or whether a concentrate was stored correctly after testing. These factors can affect the product’s condition even when the original cannabinoid and safety results were acceptable.
Pay attention to the report’s footnotes. They may explain whether results are reported on a wet-weight or dry-weight basis, whether a value is below the limit of quantification, and which regulatory standard was used. A result without units or a clear testing method is harder to interpret responsibly.
If a product page and COA appear inconsistent, pause before purchasing or using the product. The batch number, product name, test date, and package weight should make sense together. Customer support can help clarify product documentation, but consumers should rely on the final, batch-specific report and legally required labeling.
A practical review before purchase
Reading every page of a COA is unnecessary for a quick product check. Focus on identity first, then potency, then the safety panels that apply to the item. This sequence helps prevent a high THC result from distracting you from a missing or failed contaminant test.
Use these checks when reviewing a cannabis lab report:
- Match the product name, batch number, package size, and report date.
- Confirm the laboratory and report identifier are clearly listed.
- Read total THC alongside THCA, THC, CBD, and other reported cannabinoids.
- Review terpene results for aroma and flavor context, without treating them as effect guarantees.
- Check pesticide, heavy metal, microbial, mycotoxin, and residual solvent results for pass or ND status where applicable.
Keep a copy or screenshot of the report for products you purchase, especially when comparing batches over time. Results can change between production runs, and a newer report may provide more relevant information than an older document with a similar product name.
Make lab data part of a broader decision
A lab report is one part of responsible cannabis shopping. Product format, intended use, serving size, personal tolerance, storage conditions, and legal requirements all matter. Concentrates such as Diamonds and rosin are typically much more potent by weight than flower, while carts and infused products may require careful attention to the amount used per draw or serving.
For first-time purchases, begin with the label and the applicable serving guidance, then use the COA to verify the product’s composition and safety results. Avoid assuming that a higher number automatically represents better quality. A balanced terpene profile, clear documentation, suitable format, and reliable storage may be more relevant than a small difference in potency.
