How to read Kratom lab test results

The Kratom plant (Mitragyna Speciosa) grows naturally and on developed farms all through its native land in places like Malaysia, Indonesia, and other southeast Asian countries. To make the plant material accessible for you as the customer, a long handling and supply chain is required to take the leaf from its original, natural form to the pure, fine powder format you expect from Kratom Virtue.

Despite the fact that our premium Kratom powder might appear as a basic, simple substance, a ton of difficult work goes into guaranteeing that it’s the cleanest and most flawless Kratom powder on the market.

Lab testing is one of the key steps in that supply chain to guarantee safety and quality. Every time our Kratom is lab-tested for purity and potency, the lab we work with returns a Certificate of Analysis that includes the lab test results for the Kratom lot we sent them. These analysis reports are stored online and made available to all customers.

What we’re testing for

In the botanicals business, testing labs are employed to evaluate tests for a wide assortment of substances that are for the most part viewed as risky for human utilization at explicit amounts or potencies. A considerable amount of these substances are totally innocuous when used in small amounts.
As a matter of fact, each time you inhale, you’re consuming immaterial amounts of spores and microbes. It’s undeniable except if you live in a disinfected, controlled clean room. The small, infinitesimal particles and microorganisms we live around aren’t in a sufficiently high amounts to represent any critical danger to our wellbeing. Also, the modest quantities that we really do consume are effectively managed by our immune system.
The labs we, as a rule, work with test for material grouping of two primary classifications of substances: weighty metals and microbes. Our labs additionally test for the presence of specific plant alkaloids.


All batch lab tests performed on Kratom Virtue Kratom powder tests for the presence of, at the very least, the following heavy metals:
– Mercury (Hg)

– Lead (Pb)

– Arsenic (As)
– Cadmium (Cd)
The equipment and methods used to test for these substances are amazingly complex. We will not carefully describe them here beside saying that they include the utilization of a high level natural material testing method called Inductively Coupled Plasma Mass Spectrometry — or ICP-MS.
Keep in mind, it’s difficult to dispose of every molecule of all destructive substances. The whole point behind lab testing is to acquire scientifically based visibility into the levels of these substances that are present in the batch being tested and afterward to give that knowledge to you as the Kratom customer.
While the risk posed by heavy metals build up over time, the risk with exposure to microorganisms is immediate sickness or bacterial disease. This goes for any unsafe microbe your immune system could experience, from microscopic organisms to infections to mold spores.Basically, a microorganism is an organism that can cause harm in a host. What’s more, a microorganism is essentially a living cell, or tiny organism.The microorganisms that are evaluated for in the labs we work with include:

  • E. Coli
  • Staphylococcus Aureus
  • Salmonella
  • Coliforms (a group of microorganisms generally found in soil and water)
  • Yeast
  • Mold

The last two — yeast and mold — are evaluated for not on the grounds that they are essentially hazardous to all individuals (despite the fact that they can be in sufficiently high fixations). Rather, yeast and mold can have antagonistic responses for certain individuals with specific sensitivities. Accordingly, our labs guarantee that their distinguishable existences are lower than established boundaries.


As well as testing for heavy metals and microbes, our labs additionally check for the presence of explicit plant alkaloids that normally appear in the Kratom leaf. Kratom alkaloids are basically molecules that are naturally occurring in the kratom plant, like its leaves, roots, and stems. For instance, caffeine is an alkaloid that happens normally in the coffee plant.

Not all Kratom alkaloids produce effects. The alkaloids that unquestionably do are: Mitragynine and 7-Hydroxymitragynine.

Whenever these two alkaloids are present with the expansive range of the other 20+ Kratom alkaloids, an synergistic impact can happen. This effect can differ generally as indicated by various factors like Kratom plant climate, soil type,  and reaping/drying strategies.

On account of the significance of Mitragynine and 7-Hydroxymitragynine concentrations, our labs utilize a testing methodology called High Performance Liquid Chromatography to identify the specific grouping of every alkaloid in the batch being tested. Higher densities of these two alkaloids, taking everything into account, are frequently connected with improved Kratom powder efficacy.


Kratom lab testing results should include information on the following pathogens:

  • Coliforms – a group of bacteria present in plant material,
  • Mold – mold spores can be toxic to humans and can cause allergies, poisoning, or other negative reactions,
  • Salmonella – exposure to it can result in a salmonella infection,
  • E.coli – not washing your hands after handling contaminated kratom can transfer the bacteria to your mouth and cause a gastrointestinal infection,
  • Yeast – yeast is a form of fungus and may contain mold toxins,
  • Staphylococcus aureus – bacteria that can cause staph infections.

Pathogens may be present in minimal amounts that a healthy human immune system is more than capable to handle without causing any issues. Nevertheless, if the pathogens exceed the permitted limits, the product is unfit for sale.

Below are the specifics on the limits required for the product to pass the test:

  • Coliforms – under 10,000 CFUs (colony forming units) per gram,
  • Mold – under 100,000 CFUs per gram,
  • Salmonella – not detected in 25 grams
  • E. coli – not detected in 10 grams
  • Yeast – under 100,000 CFUs per gram,
  • Staphylococcus aureus – not detected in 10 grams

Heavy metals are another class of dangerous substances that can be present in kratom. They are widely present in the environment around us and can get into kratom from soil and water as well as during the manufacturing process.

Heavy metals in kratom have been a topic that reached the news. In spring 2019, the FDA tested 30 different kratom products from various vendors,  and discovered dangerous levels of nickel and lead in them.

Kratom lab testing looks at the presence of lead, cadmium, arsenic, and mercury. Below are thresholds of heavy metals that are acceptable in kratom products:

  • Lead (Pb) – below 1.2 PPM (parts per million),
  • Arsenic (As) – below 2 PPM,
  • Cadmium (Cd) – below 0.85 PPM,
  • Mercury (Hg) – 0.41 PPM

While it may seem alarming that there are heavy metals in kratom even if in small amounts, traces of them may be present and impossible to avoid or eliminate. However, when their levels are high, they can become dangerous to human health.

Kratom lab test results might appear to be complex. In any case, understanding what you are reviewing can assist you with determining the quality and safety level of the any Kratom powder product.
