General Information
Is your laboratory certified?
Yes, in addition to a business license and a special permit for handling cannabis, our laboratory’s quality management system is certified according to the international standard ISO 9001:2025. This is reviewed annually. Here is our certificate.
Can a private person also send in tests?
Yes, we also analyze samples from private individuals. Our test kits are specifically designed to enable anonymous testing.
From which countries can samples be submitted?
How long does it take to get the results?
Here are the usual processing times after sample receipt, depending on the type of analysis:
Virus/Fungal Analysis: 1–2 business days
Gender Tests: 1–2 business days
Cannabinoid Analyses: 1–2 business days
Terpene Analyses: 1 week
Heavy Metal Analyses: 2–3 weeks
Microbial Analysis (Determination of Colony Count): 2–3 weeks
Do you also offer special conditions for business customers?
Am I allowed to publish the test certificates?
Yes, you are allowed to publish all certificates issued by us, including for advertising purposes. The condition is that you do not alter the certificate in any way, which also means you cannot publish only parts of it. Do not modify certificates without consulting the laboratory, as this could potentially be considered document forgery. If you are the owner of a certificate and wish to request a name change or correction, please contact us by email at
Are the test kits intended for testing at home?
Samples must be brought to our laboratory, where they are analyzed by experienced molecular biologists and chemists to ensure accurate results. Home testing is not possible.
Can samples also be submitted directly without a test kit?
Yes, we also accept samples without a test kit. Simply follow the instructions in our sampling guide and send the sample to us (shipping address is in the sampling guide). Please notify us of your sample in advance by email and label the samples so that we can identify them. If you send the sample directly to us instead of ordering through the online shop, payment can only be made in advance. Tiered pricing is also available in this case.
Hop latent viroid-/ Pathogen-tests
Why should one test for HLVd?
Diseases like Hop Latent Viroid often remain undetected for a long time but can lead to reduced vitality and crop losses. Laboratory testing helps detect infections early and prevent their spread. More information about hop latent viroid here.
What type of sample material can be submitted for HLVd testing?
Tests can generally be performed using any part of the plant (leaf, root, stem, flower). The best material is from the upper roots. Collect about 2–3 cm of roots and roughly remove any soil.
If the roots are not easily accessible, leaf petioles from lower leaves are also suitable. An ideal sample includes both leaf petioles and root parts, covering different parts of the plant. About a thimble-sized amount of tissue is sufficient for testing. More information can be found in our Sampling Guide.
Is it also possible to test seeds for HLVd?
Yes, testing seeds for Hop Latent Viroid and other pathogens is possible at no extra cost. We recommend combining at least 5 seeds from one batch/harvest into a single sample. This provides a representative result for the rest of the seeds from that batch. If you want to test purchased seeds, a single seed is generally sufficient as the starting material.
Which plants can be tested for HLVd, and how old do the plants need to be?
Plants can be tested at any growth stage. We recommend testing cuttings only once they are well-rooted.
Which method do you use to detect viruses?
We use the highly sensitive RT-qPCR method, which allows the detection of viral genetic material with as few as around 100 gene copies per milliliter of sample. This method is considered the gold standard for virus detection.
Cannabinoid & Terpene Analyses
Which cannabinoids can you measure?
Our standard cannabinoid analysis includes the following cannabinoids:
Delta-9-THC
Delta-8-THC
THCA
CBD
CBDA
CBG / CBGA
CBC
CBN
THCV
CBDV / CBDVA
HHC
Can you also detect synthetic cannabinoids?
Yes, we also offer a screening method using mass spectrometry for a wide range of synthetic cannabinoids. The specific compounds included can best be found in our sample report here.
What types of samples can you analyze?
We can analyze almost any type of sample:
Flowers
Hash
Oils / tinctures
Creams
Gummies
Isolates
Cake
Chocolate
Which method do you use to analyze the samples?
For standard cannabinoid analysis, we use the HPLC method (high-performance liquid chromatography).
For screening synthetic cannabinoids, we use GC-MS (gas chromatography coupled with mass spectrometry) or HPLC-MS.
Cannabis Sex Testing
What type of sample material can be submitted for sex determination tests?
For cannabis sex determination tests, a fingernail-sized piece of leaf is sufficient. More information can be found in our Sampling Guide.
How old does a plant need to be to perform a sex determination test?
There is no minimum age-limit. As soon as the plant is large enough to provide a fingernail-sized piece of leaf without being harmed, the test can be performed.
Can hermaphrodite plants also be identified in sex determination tests?
No, the sex determination test identifies the genetic sex of the plant. Under normal conditions, plants express only their genetic sex. Both male and female plants have the ability to develop hermaphroditic traits. This is hormonally controlled and typically occurs under stress conditions.
