If you see 7-OH on a lab report, start with the analyte name, the exact batch number, and the unit beside the result. A number is useful only when the report identifies what was tested and what that number is measured against; it does not, by itself, tell you what a different product or a different batch contains.
7-hydroxymitragynine, usually shortened to 7-OH, is an alkaloid associated with kratom. The FDA’s kratom overview says 7-OH occurs naturally in kratom leaf but is a minor constituent, accounting for less than 2% of total alkaloid content in natural leaves. That description is not a per-gram result and should not be used as one.
Is 7-OH actually tested on this report?
It is tested only when the report’s analyte list names 7-hydroxymitragynine, 7-OH, or an equivalent laboratory analyte. A report may include other alkaloids, contaminants, or microbiology without including a 7-OH result.
Check the report in this order:
- Match the lot or batch number on the package to the report.
- Find the alkaloid panel and look for 7-hydroxymitragynine by name.
- Read the result, unit, method, date, and any reporting limit on the same row.
- Keep the product label and matching report together rather than assuming a report applies to a whole product line.
Urban Ice Botanicals describes alkaloid content on a COA as a section that may quantify mitragynine and 7-hydroxymitragynine, while also noting that reports can cover different panels. An omitted 7-OH row means this document cannot answer the 7-OH question for you. Ask the seller or laboratory for the matching report that names the analyte.
Is the result per gram or per product?
Read the denominator before reading the number. Urban Ice Botanicals says a result shown as w/w% is a weight-by-weight percentage: it describes the compound’s share of the tested sample by weight. A percentage on a COA is therefore tied to that sample, not automatically to an entire container, tablet, serving, or another batch.
| What you see | What it tells you | What to check next |
|---|---|---|
| 7-OH listed with w/w% | A weight-by-weight result for the tested sample | Match the sample and batch to your label |
| 7-OH listed with another unit | The laboratory used that unit for the tested sample | Read the report’s unit and method notes |
| Product weight on the label | The amount of material in the package or format | Do not treat it as a lab result unless the documents explicitly connect them |
| No 7-OH row | This report does not provide a 7-OH measurement | Request an analyte-specific, batch-matched report |
Do not turn a percentage into a use amount or compare formats by potency from this page. The National Center for Complementary and Integrative Health says kratom products vary in their combination and concentration of compounds, making effects difficult to predict. A leaf product, extract, tablet, drink, or other format also should not be treated as interchangeable just because each uses the word “kratom.”
What does the reporting limit mean?
A reporting limit tells you where the laboratory can reliably make the type of statement shown on that report. Urban Ice Botanicals defines the limit of quantitation, or LOQ, as the lowest amount the equipment can reliably quantify. If a 7-OH result says “below LOQ,” keep that wording intact; it is not a measured numerical result you can substitute into another calculation.
“Not detected,” “below LOQ,” and a reported number are different report entries. Read the lab’s own definitions and the method notes before treating any of them as the same thing. If those definitions are not on the document, ask the laboratory to explain the reported limit and whether 7-OH was included in the method.
What does a 7-OH result leave unanswered?
A single COA cannot establish the composition of another batch, another product, or a person’s response. It also cannot tell you whether a substance will appear on a particular workplace, military, probation, or other drug-testing panel. ANR Clinic states that standard panels do not routinely screen for kratom alkaloids, while specialized tests can be ordered; the practical next step is to ask the testing program which analytes and confirmation methods its panel uses.
It also cannot settle every health question. The National Center for Complementary and Integrative Health says research on kratom remains early and that short- and long-term effects are still being studied. The FDA warns about serious adverse events, including liver toxicity, seizures, and substance use disorder. If a clinician is making decisions about your care, bring the label and the full COA rather than relying on a product name or a single lab number.
For context on how product names can differ from a document’s actual contents, see White Thai Kratom and White Bali Kratom. A strain name is not a substitute for a batch-matched analyte panel.
Annotated label and COA checklist
Use this checklist with the package and report side by side:
- Identity: Is the product name, format, lot or batch number, and report date present on both documents?
- Analyte: Does the report explicitly name 7-hydroxymitragynine or 7-OH?
- Denominator: Is the result a w/w percentage or another stated unit, and is it clearly tied to the tested sample?
- Limit: Does the row show a number, “not detected,” or “below LOQ,” with the laboratory’s definition?
- Scope: Which panels are present: alkaloids, microbiology, heavy metals, or something else?
- Unresolved identity: If the label and report cannot be matched, do not rely on that report to identify the product.
What to do next
Keep the question narrow: first confirm whether 7-OH was tested, then confirm the sample basis, then read the reporting limit. If the product identity or batch match remains unresolved, no recommendation follows from the document. For a medical concern or a medication decision, share the complete label and report with a clinician.
