GetTested’s Leaky Gut Test is a test that measures zonulin. Excessive levels of zonulin are linked to leaky gut. Leaky gut means that particles such as undigested food, toxins and microbes can penetrate the intestinal barrier and enter the blood, which disrupts the immune system, increases inflammation in the body and can lead to a number of different diseases.

What is Leaky Gut?

Leaky gut describes damaged, overly permeable intestines. This damage lets particles like undigested food and bacteria enter the blood. The immune system reacts, thinking it’s under attack. This can trigger diseases like hypothyroidism, psoriasis, allergies, and fatigue.

If untreated, leaky gut can cause food intolerances, stomach issues, fatigue, brain fog, skin problems, and depression. Many don’t realize they have it, making testing crucial. Zonulin levels indicate leaky gut and often rise in allergies, autoimmune diseases, and rheumatism. Monitoring zonulin can help optimize health.

What is zonulin?

Zonulin is a protein made in intestinal and liver cells. It controls intestinal permeability. Zonulin affects the “tight junctions” between digestive tract wall cells. It lets nutrients enter the bloodstream. If these junctions are damaged, big protein molecules can get through. This can cause inflammation.

Who would benefit from the Leaky Gut Test?

This test measures zonulin, which is a marker for leaky gut. If you experience more gut issues, we can recommend our more comprehensive gut health test, Gut Microbiome XL, which also measures the status of your gut flora, i.e. bacteria and fungal overgrowth (incl. Candida), as well as digestive function.

How does the Leaky Gut Test work?

You can do all our health tests, including our stool tests, at home. The test kit contains everything you need. After performing the test, send it to our ISO certified lab. You will then get your result digitally.

  8. Alejandro

    Over the past year, I experienced a variety of symptoms that neither I nor my doctors could put a finger on. From sudden food intolerances to persistent fatigue, it felt as though my body was sending out distress signals. A friend mentioned the possibility of a “leaky gut,” a term I had vaguely heard but never explored. Curiosity piqued, I decided to try the Leaky Gut Test. The experience from start to finish was seamless. The kit arrived in a timely manner, and I appreciated the straightforward instructions that came with it, making the entire process hassle-free.

    Receiving the results was a revelation. Not only did they pinpoint issues with my gut permeability, but they also provided in-depth insights into areas of concern and possible triggers. With this newfound knowledge, I embarked on a targeted health journey, working alongside my nutritionist to address these issues. In a matter of months, I’ve witnessed noticeable improvements in my health. To anyone grappling with unexplained health issues, this test could be the missing piece of your puzzle.

  10. Liam

    Growing up, I had always been the person with an ‘iron stomach’ – able to devour any culinary delight without a second thought. So, when I began facing digestive woes, irregular energy levels, and even cognitive fog, it was both baffling and alarming. Numerous visits to medical professionals yielded a mosaic of non-specific advice, from “maybe it’s just stress” to “perhaps you should get more sleep.” Nothing seemed to resonate with the actual changes I was feeling within. A well-read colleague suggested exploring the idea of a ‘leaky gut,’ a concept I had never ventured into. Out of sheer desperation and curiosity, I sought out and found the Leaky Gut Test. From the outset, the journey was comforting. The test kit, which was delivered promptly, showcased an exemplary level of detail, ensuring even someone medically naive like myself could administer it without hitches. The entire procedure felt more interactive than clinical, making it less daunting. When the results arrived, they were an amalgamation of clarity, validation, and education. They didn’t just stop at confirming a compromised gut lining; they delved deep, explaining the possible implications and underlying causes of such a condition. The insights were startling; highlighting how a disrupted gut could potentially ripple out, affecting a myriad of bodily functions, even ones I hadn’t considered. With the data in hand, I took actionable steps. Partnering with a nutritionist, I embarked on a tailored healing regimen. Slowly but steadily, the fog lifted. Digestive episodes reduced, energy levels stabilized, and the constant mental fatigue began to wane. Reflecting back, I see the Leaky Gut Test not just as a diagnostic tool, but as a beacon – illuminating the path back to holistic health. For anyone submerged in the quagmire of unexplained health anomalies, this could be the guiding light you’re desperately seeking. 🙂 🙂 🙂
