How to Read a Kratom Lab Report Against the Proposed 7-OH LimitsGloved hands using a micropipette to spot a sample onto a thin-layer chromatography plate in a lab

A kratom lab report now has one job before any other: showing whether a product sits above or below the federal line being drawn for 7-hydroxymitragynine. On October 9, 2026, the Department of Justice said the DEA would issue a new notice of intent for 7-OH, rebuilt around thresholds recommended by HHS. Most certificates of analysis already carry the numbers you need. You just have to know which rows to read and what an empty cell means.

What are the proposed 7-OH thresholds?

HHS recommended Schedule I control when 7-OH, alone or combined with a related compound called mitragynine pseudoindoxyl (MGPI), exceeds 1 milligram per gram in a solid product or 1 milligram per milliliter in a liquid. There’s a second test that catches products the first one misses. If the ratio of mitragynine to 7-OH drops below 100 to 1, the product is covered too.

That ratio test is the part most buyers haven’t absorbed yet. HHS designed it to separate products whose alkaloid mix looks like ordinary kratom leaf from products that have been enhanced or concentrated. So a product can stay under the per-gram limit and still fail on proportion.

Timing matters as well. The DOJ release confirmed that the DEA had not yet issued a temporary scheduling order for 7-OH itself. MGPI is a different story. It has been in temporary Schedule I since August 26, 2026, alongside two lab-made derivatives sold as MGM-15 and MGM-16.

Which rows on a certificate of analysis actually matter?

It helps to work through a real report. ProVerde Laboratories in Milford, Massachusetts tested a mitragynine tablet sample on February 25, 2026 under certificate 136612, lot MCP150. The lab lists accreditation to ISO/IEC 17025:2017 through PJLA under accreditation number 80585. Its method was liquid chromatography with PDA detection.

Start with the analyte list

Before you look at a single result, read down the left-hand column. This report covers five alkaloids, from mitragynine through to 7-hydroxymitragynine. Anything missing from that column wasn’t measured. That matters, because MGPI isn’t on it, and under the new proposal MGPI is counted alongside 7-OH.

Then check the units

Labs report the same quantity in several ways, and mixing them up is the most common reading error. The conversion you need is short: 1 percent by weight equals 10 milligrams per gram, which equals 10,000 parts per million. The proposed 1 mg/g line therefore works out to 0.1 percent, or 1,000 ppm.

In the ProVerde report, mitragynine comes in at 19.1 percent by weight. The 7-OH row reads 0.00 percent, or 0 ppm, with a footnote saying anything below 0.005 percent (50 ppm) is recorded as not detected.

Liquids work slightly differently. Reports on shots and syrups usually give results in milligrams per milliliter, and the proposed liquid limit is also 1 mg/mL, so you can compare those directly without converting anything.

Then do the ratio yourself

Labs rarely print the ratio, so you’ll have to work it out. Take the mitragynine figure and divide it by the 7-OH figure. When 7-OH is not detected, use the detection limit as your worst case. For this sample that’s 19.1 divided by 0.005, which gives a ratio of at least 3,820 to 1, more than 38 times the 100-to-1 floor.

That certificate belongs to a batch of full spectrum mitragynine tablets sold on blister cards, and the retailer posts a report beside each flavor on the product page. That’s the format worth looking for: one report per product, with a lot number you can match against the package in your hand.

What does “not detected” really mean?

It doesn’t mean zero. It means the compound, if present, sits below the lab’s limit of detection. ProVerde’s limit for this panel is 50 ppm, which equals 0.05 mg/g. Even at that worst case, the sample would sit 20 times under the proposed 1 mg/g line.

Detection limits vary a lot between labs, and that’s worth knowing before you compare two reports. PharmLabs, a California lab that tests many of the botanical tablets now sold beside kratom, lists a 7-OH detection limit of 0.008 ppm on its kratom panel. A “not detected” from that lab is a far stronger statement than one from a lab working at 50 ppm.

Should non-kratom products be tested the same way?

Yes, and in 2026 it’s arguably more important. In July, the Utah Department of Agriculture and Food warned the public about Buzzers brand tablets sold as cat’s claw after testing found kratom alkaloids in several flavors. State officials said they were investigating a death and several severe cases that may be linked to the products. Poison centers elsewhere have since warned that some “cat’s claw” products contain unlabeled 7-OH.

The fix is the same panel. Here’s a report for a cat’s claw tablet run through the same kratom panel: PharmLabs reported on September 9, 2026 that six kratom alkaloids, including MGM-15 and mitragynine pseudoindoxyl, were not detected. That’s the result you want from a product that claims to contain no kratom at all.

What if the panel doesn’t test for MGPI?

Most kratom panels written before this year don’t include it. That’s a real gap now, because the proposal counts MGPI and 7-OH together against the same 1 mg/g limit. HHS also said MGPI may occur at trace levels in some botanical products, so a missing row can’t be read as a zero.

If the report you’re reading has no MGPI line, ask the seller whether a newer panel exists. Some labs now list it by name, often as mitragynine pseudoindoxyl. A seller who has already retested will usually say so in a single email.

Where do lab reports fall short?

Any certificate has an honest limitation: it describes one sample, taken from one lot, on a single test date. A report from February says nothing certain about a tablet pressed in September. Some reports also carry a note saying the sample contained unidentified peaks the lab doesn’t test for, which means something showed up that the panel can’t name. If a product’s credibility rests entirely on a single old report, treat that as a gap rather than a guarantee.

How do you confirm a report is genuine?

Fake and recycled certificates do turn up in this market, so checking comes before reading. Most accredited labs print a QR code or a verification link. Scan it, and make sure the lab’s own site returns the same certificate number and results you see on the retailer’s page.

Then compare the lot number on the report with the lot printed on your package. If they don’t match, the certificate tells you about a different batch. Finally, look up the accreditation number with the accrediting body. A real ISO/IEC 17025 accreditation can be confirmed in under two minutes.

Where does this leave kratom buyers in late 2026?

Federal scheduling is only one layer. Tennessee’s kratom ban, known as Matthew Davenport’s Law, took effect on July 1, 2026. The California Department of Public Health says kratom and 7-OH products are illegal to sell for consumption in the state. Other states have their own rules, so check where you live first.

The FDA hasn’t approved kratom for any medical use and warns consumers not to use it, citing risks that include liver toxicity and seizures. Nothing on a lab report changes that position. What a report can do is tell you whether a product is what its label says.

My advice for this year is blunt. A kratom product without a batch-matched, verifiable certificate isn’t worth your time. Run the ratio math on every product you’re considering. It takes about thirty seconds, and if the numbers needed to do it aren’t published, you already have your answer.
