KBMO FIT 176 (including the gut barrier panel) Food Sensitivity Tests
Please note that the interpretation of test results is not included. For this, you’ll be required to book a food sensitivity results interpretation & follow-up appointment.
For over 2 years old
Use with caution in: Immunocompromised individuals may show reduced antibody responses, affecting test accuracy.
Food Sensitivity Assessment (FIT 176): Evaluates sensitivities to 176 different foods and additives, encompassing all major food groups, including dairy, grains, fruits, vegetables, meats, nuts, seeds, fish, shellfish, spices, and food additives. It measures:
- IgG Antibodies: Immunoglobulin G antibodies, which can indicate delayed food sensitivities.
- Immune Complexes (IgG + C3d): This is the binding of IgG antibodies to food antigens, which can lead to inflammation and various health issues.
Gut Barrier Panel (GBP): The GBP is integrated into the FIT 176 test to provide an in-depth analysis of gut health and intestinal permeability, often referred to as “leaky gut.” This part of the test measures several key biomarkers, including:
- Candida: A yeast that can overgrow in the gut, potentially causing digestive and immune issues.
- Zonulin: A protein that regulates the tight junctions between intestinal cells. Elevated levels of Zonulin are a sign of increased intestinal permeability.
- Occludin: A protein involved in maintaining the tight junctions between gut cells. Lower levels can suggest a compromised gut barrier.
- Lipopolysaccharides (LPS): Toxins from certain bacteria in the gut. Elevated levels are often associated with leaky gut and systemic inflammation.
Sample Collection: The test requires a finger-prick blood sample, allowing for convenient at-home testing. Alternatively, it can be arranged in our clinic for an additional fee.
Turnaround Time: 14 Working Days
Finger-prick tests are generally suitable for individuals aged 2 and over. For blood serum sample collection, the minimum recommended age is 12 and above.
KBMO Gut barrier panel (GBP) Food Sensitivity Tests
Please note that the interpretation of test results is not included. For this, you’ll be required to book a food sensitivity results interpretation & follow-up appointment.
For over 2 years old
Use with caution in:
- Immunocompromised individuals may show reduced antibody responses, affecting test accuracy.
KBMO has created a unique Gut Barrier Panel in recognising that leaky gut occurs across a spectrum. We have included the following gatekeeper markers:
- Zonulin: A protein that modulates the permeability of tight junctions between intestinal cells. Elevated levels suggest increased intestinal permeability.
- Occludin: A structural protein critical for maintaining tight junction integrity. Elevated antibodies may indicate tight junction breakdown.
- Lipopolysaccharides (LPS): Components of gram-negative bacterial cell walls. Elevated antibodies can reflect translocation into the bloodstream due to increased intestinal permeability.
- Candida: A type of yeast that naturally resides in the gut. Overgrowth can disrupt gut flora balance and contribute to leaky gut.
Sample Collection: The test requires a finger-prick blood sample, allowing for convenient at-home testing. Alternatively, it can be arranged in our clinic for an additional fee.
Turnaround Time: 14 Working Days
Finger-prick tests are generally suitable for individuals aged 2 and over. For blood serum sample collection, the minimum recommended age is 12 and above.

Common Q&A about Food Sensitivity Tests
Our FAQ section is designed to address common questions you may have, from how our treatments work to what you can expect during and after your session.
Our team is always available to provide additional support if you need more personalised guidance, ensuring that you feel informed and confident every step of the way.
A food sensitivity test measures your body’s immune response to certain foods by detecting levels of specific antibodies (such as IgG) that may indicate an intolerance. It helps identify foods that could be causing symptoms like bloating, headaches, or fatigue.
A food allergy test identifies immediate, potentially life-threatening immune reactions (IgE antibodies), while a food sensitivity test detects delayed responses (often through IgG antibodies), which can cause symptoms hours or days after consuming a food.
Common symptoms include digestive issues (bloating, diarrhea, constipation), skin problems (rashes, eczema), headaches, fatigue, joint pain, and difficulty concentrating. These symptoms are often subtle and delayed.
Most tests require a blood sample, which is analyzed for immune responses to specific foods. Some tests use a finger-prick blood sample that can be collected at home, while others require a full blood draw.
The accuracy of food sensitivity tests is debated. While some people find them helpful in identifying foods that trigger symptoms, others believe they can produce false positives or negatives. It’s best to interpret the results in conjunction with a healthcare professional.
Food sensitivity tests can offer helpful clues, but their accuracy varies because many measure IgG antibodies, which reflect exposure rather than true intolerance. On their own, they can produce false positives or overlook important triggers. At The Health Suite, these tests are never used in isolation; instead, results are interpreted by a functionally trained doctor or nutritionist alongside your symptoms, medical history, gut health, and blood markers. When used within this broader clinical context, food sensitivity testing becomes a useful tool to guide targeted dietary adjustments and safe, evidence-informed elimination and reintroduction plans.
No, food sensitivity tests are not diagnostic tools for diseases. They are intended to guide individuals in identifying potential food triggers, but they should not replace medical advice for conditions like celiac disease, IBS, or food allergies.
If your test indicates food sensitivities, it’s recommended to follow an elimination diet under the guidance of a nutritionist or doctor. You’ll remove the suspected foods from your diet for a period, then slowly reintroduce them to observe if symptoms reoccur.
Yes, food sensitivities can fluctuate depending on factors like gut health, stress, and diet. Some people may develop sensitivities to new foods, while others may tolerate foods they previously reacted to after healing their gut or eliminating the triggers for a time.
At-home food sensitivity tests can provide useful insights, but their reliability can vary. It’s crucial to follow the instructions carefully and interpret the results with caution, preferably with professional advice, to avoid unnecessary dietary restrictions.
Common food sensitivities include dairy, gluten, eggs, soy, nuts, and certain fruits or vegetables. However, sensitivities can vary widely between individuals, so personalized testing may reveal different trigger foods.

If you are experiencing any of these symptoms, please book an appointment with us. Symptoms can vary from person to person and from condition to condition.A proper diagnosis can only be made through a thorough medical examination.
Our clinicians will carry out a full assessment to ensure an accurate diagnosis and appropriate care.
Do you experience frequent bloating or digestive discomfort after eating?
Persistent bloating, gas, or abdominal pain after meals may be linked to food sensitivities. Testing can help identify triggers and guide personalised dietary adjustments.
Are you struggling with unexplained fatigue or low energy?
Feeling unusually tired could be related to how your body reacts to certain foods. Identifying sensitivities may reveal patterns that help improve energy and overall well-being.
Do you notice recurring skin issues like rashes or irritation?
Some people find that food triggers can worsen skin flare‑ups, redness, or itching. Food sensitivity tests can pinpoint possible culprits to help guide diet changes.
Are you bothered by headaches after eating certain foods?
Headaches or migraines linked to food intake could be a sign of sensitivity. Testing helps identify possible problem foods so you can adjust your diet more effectively.
Do you have joint discomfort or inflammation of unknown cause?
Food‑related inflammation can contribute to achy joints or stiffness. Food sensitivity testing may help uncover foods that trigger inflammation for targeted management.
Are you experiencing digestive issues combined with mood changes?
Symptoms like indigestion paired with mood swings or irritability may relate to gut‑food interactions. Identifying food triggers supports customised nutrition plans.
