- Zonulin Test
Verisana measures the Zonulin value of your gut, which plays an important role in diagnosing the so called "Leaky Gut Syndrome", as it gives an indication of the permeability of the gut mucosa.
Availability: deliverable immediately
Who should take the test?
The complex interaction of food allergens, microorganisms, epithelium and immune system influences the development of many chronic diseases. Above all, a permeable intestinal mucosa - the leaky gut syndrome - plays a central role.
The protein molecule zonulin is a suitable marker to measure the permeability of the intestinal mucosa. Zonulin regulates the exchange of fluid, macromolecules and leukocytes between bloodstream and intestinal lumen. High zonulin values can typically be observed in case of Diabetes Type 1, autoimmune diseases, celiac disease, multiple sclerosis, rheumatoid arthritis and other chronic diseases.
The test analyzes the values of the following protein molecule:
- - Zonulin
Our Zonulin Test gives you information about the zonulin concentration in your gut. This value plays an important role in diagnosing the so called "Leaky Gut Syndrome", as it gives an indication of the gut permeability.
How does it work?
You collect the samples at home, send them back to us and we will provide you with your level of each protein molecule and whether your level falls within the reference ranges for your age. In addition to that, the results include graphs showing whether your are in the "green" (=normal/healthy) or "red" (=too high/low) area, making it easy to understand the results.
What will my results tell me?
Your results will provide detailed information about whether your zonulin level is normal, low, or high compared to reference ranges in your age group. You can then discuss the results with your doctor or health practitioner, who can give you further guidance and treatment recommendations.
What guidance will I get along with my results?
We always recommend the discussion of the mailed results with your doctor or practitioner. Although we do not offer therapy service ourselves, we will gladly assist you in finding a suitable therapist in your area. Besides, further information is available on our website, especially in the different test categories, under "health conditions" and the FAQs. Still have questions?

For the Zonulin Test we analyse:
Zonulin is a protein molecule that helps with the regulation of tight junctions in your intestinal wall. When it connects to specific receptors on the cell surface, the tight junctions open up and therefore increase your intestinal permeability. This can be caused e.g. by being exposed to certain types of bacteria. The ensuing exposure to foreign antigens and cell components can cause immunological reactions and dysregulations. High Zonulin values can typically be observed in case of Diabetes Type 1, autoimmune diseases, celiac disease, multiple sclerosis, rheumatoid arthritis and other chronic diseases.
Please note the following guidelines regarding the stool collection - the correct collection of the stool is important for achieving analtered laboratory results! Please make sure to collect the samples on Mondays and post them the same day.
Before the sample collection
1. Label the sample container with your full name, the date as well as the time of the sample collection.

During the sample collection
1. Please use the enclosed stool collection unit to avoid the stool coming in contact with toilet water or urine. Now collect the sample using the stool collection unit.
2. Take the enclosed collection spoon (attached underneath the lid) in order to stir the stool. Collect different samples from different areas of the stool.
3. Fill the container with the stool sample until the tube is ¾ full.
4. Close the sample container tightly with the lid and clean the outside surface if necessary
After the sample collection
1. After the collection, the stool collection unit as well as the remaining stool can be flushed down the toilet.
2. The sample can be placed in the refrigerator over night – please do not freeze!
3. Please collect the sample on Mondays and post them the same day.
4. Place the sample in the delivered protective bag (clear bag with blue border). Then place everything together with the enclosed sample dispatch note in the grey plastic envelope and seal it.
5. For shipping, please use a „Priority Mail Padded Flat Rate Envelope“. The envelopes are available for free. Put the sealed grey envelope into it and send it to the following address: Brian Kalish c/o Verisana Laboratories 818 N Quincy Street Unit 806 Arlington VA 22203.
You can either receive the „Priority Mail Padded Flat Rate Envelope“ at any US Postal Service Center, where you can also pay and dispatch your item.

You can then dispatch the envelope at your local post office or throw it into the next letter box (make sure it is emptied the same day!).
Please note: In accordance with the general postal regulations the sender bears the legal responsibility.
6. After approximately 14-21 days you will receive your results.
We advice you that we assume no liability for any disadvantages, costs or damages arising from incorrect collection or shipping. Samples that arrive to our laboratory due to shipment on the wrong weekday, delays in shipping services, selection of incorrect shipment services or providers, or due to force majeur may not fulfill requirements for laboratory testing anymore and may therefore have to be retaken at the sole expense of the patient.

The withdrawal period from the purchase of all our items is 2 weeks from the receipt of the goods. Please inform us via mail about the desired cancellation and note the following information: Laboratory analyzes can only be canceled if the analysis has not yet been carried out.
How long will it take to receive my findings?

How do I get my findings?
You will receive your findings via mail.
Can I get advice for my test result? Can you tell me what remedy to take?
For legal reasons, our findings do not include individualized therapy recommendations.
If you have any questions regarding the understanding of your findings, please contact our laboratory team.
I forgot to put the sample dispatch note in the package when sending the sample back.
Please send us the completed and signed dispatch note, preferably by mail to firstname.lastname@example.org. Unfortunately, we can not complete your sample without a dispatch note.
I take medication. Can this affect the outcome?
That depends on the test you want to carry out and the medications you are taking. In case of doubt, please ask your doctor regarding the areas that are influenced by the medication prescribed by him and do not stop taking your medication without consulting him.
How long can you store or use stool samples?
Basically, it is recommended to send the samples as soon as possible after collection and keep them in the refrigerator until they are shipped (do not freeze). On the way, the samples will last up to 7 days without any problems, when it is not too hot outside.
I take probiotika. Does this affect the outcome?
Taking probiotika means supplying bacteria to your body. In conclusion, carrying out a stool test while taking probiotika will make it unpossible to distinguish the amount of natural and unnatural bacteria in your gut. If you aim to find out about the amount of natural bacteria in your gut, we recommend you to stop taking probiotika two weeks before carrying out the stool test.
Does the gluten/histamine intolerance test also show a reaction when I am on a gluten/histamine-free diet?
No, you should consume food that contains gluten or histamine during the days before taking the sample to get a meaningful result.
