Comprehensive KBMO Food Sensitivity Test In Singapore

If you have ever wondered why certain meals leave you bloated, foggy, fatigued, or breaking out hours or even days later, you are not imagining it. Food sensitivities are real, common, and notoriously difficult to identify on your own, because the symptoms are delayed, overlapping, and often blamed on stress, age, or IBS. Cutting out random foods rarely fixes the problem, and aggressive elimination diets often miss the actual culprits while removing essential nutrients.

At NutraNourish, we use the KBMO FIT Test (Food Inflammation Test), a clinically validated, multi-pathway food sensitivity panel that goes far beyond standard IgG-only testing. The FIT test measures IgG and IgG immune complexes, complement activation (C3d), and gut permeability markers from a single home-collected blood spot sample, eliminating the false positives that plague single-pathway tests. Results are reviewed by Dr. Menka Gupta and turned into a personalised elimination, rotation, and gut-healing plan, so you stop guessing and start eating with confidence.

What is Food Sensitivity?

Food sensitivities cause adverse gastrointestinal responses to certain foods As a result, foods that produce a sensitivity reaction produce symptoms including abdominal pain, bloating, gas, diarrhoea, headaches, fatigue, and skin problems. Unlike an allergic reaction that occurs immediately after eating the food item, sensitivity reactions can take hours or days to occur, making it difficult to pinpoint the offending food without performing a test. Identifying sensitivities through advanced multi-pathway testing (IgG, immune complexes, complement activation, gut permeability) via KBMO/FIT can help you make dietary changes to improve your overall health and reduce any discomfort.

What is a Food Sensitivity Test?

The FIT Test is the most sensitive food test available using patented technology. The multiple pathway approach allows us to measure the whole immune system and looks at not only food sensitivities but also inflammation and gut permeability, all from one test. We also provide best-in-class compliance tools, including a personalized meal plan and a patient app to support. Measuring these multiple pathways enables us to eliminate false positive results commonly associated with IgG-only food sensitivity testing.

The Gut Barrier Panel helps practitioners differentiate the levels of gut dysfunction, from simple sensitivity to inflammation to more extreme levels of leaky gut. It measures IgG 1-4 /C3d and IgA 1-2 for three important gatekeeper markers. It is included in the FIT 176 and FIT 132 tests.

Add-On

What is the Meal Plan Add-On?

A customized seven-day meal plan is added to the FIT 132 and FIT 176 tests. Created by our nutrition team, this meal plan is personalized for the patient based on their FIT results and can be accessed through our App along with cross reactivity of foods with details about alternatives and substitutes.

Who Should Take a Food Sensitivity Test?

This test is especially valuable if you fall into any of these groups:

  • ✓You experience digestive symptoms (bloating, gas, cramping, constipation, diarrhoea) that come and go without obvious triggers
  • ✓You suspect dairy, gluten, eggs, soy, or other common foods are driving your symptoms, but cannot identify which one
  • ✓You have been assessed with IBS, but no clear food trigger has been identified
  • ✓You have skin conditions such as eczema, acne, psoriasis, hives, or chronic rashes that may be food-driven

 

  • ✓You experience frequent headaches, migraines, or sinus congestion after meals
  • ✓ You have unexplained chronic fatigue, brain fog, or poor concentration
  • ✓ You experience joint pain, muscle aches, or stiffness that fluctuates with diet
  • ✓You have anxiety, mood swings, or depression that may be linked to gut-brain inflammation

 

  • ✓You have an autoimmune condition such as Hashimoto’s, rheumatoid arthritis, lupus, or psoriasis
  • ✓You suspect leaky gut or have been on a long-term restrictive elimination diet without lasting relief
  • ✓You experience unexplained weight gain or struggle to lose weight despite a clean diet
  • ✓ You have a child with stomach pain, gut discomfort, behavioural changes, or frequent illness that may be food-related (suitable with practitioner guidance)

 

  • ✓

    You have previously done an IgG-only food sensitivity test and got a long list of positives, but no clear results

Food sensitivities accumulate silently and accelerate chronic illness, so testing is especially important for anyone optimising for long-term health rather than just addressing symptoms.

If you've answered yes to any of these questions, our advanced food sensitivity test may be the answer

Your Complete Report

What Will A Food Sensitivity Test Tell Me?

The at-home FIT Food Sensitivity Test gives you a complete, multi-pathway view of your food reactions and gut barrier function. Specifically, it tells you:

✓
IgG antibody response The level of IgG immune response to each food tested, the primary marker of delayed food sensitivity.
✓
IgG immune complexes The formation of antibody-antigen complexes circulating in your body, a more accurate indicator of clinical reactivity than IgG alone.
✓
Complement activation (C3d) The activation of the complement immune pathway in response to specific foods, confirming that your immune system is genuinely reacting (not just exposed).
✓
Severity scoring Each food and additive is colour-coded against reference ranges showing low, moderate, or high reactivity, so you can prioritise which foods to eliminate first.
✓
Sensitivity to 22, 132, or 176 foods and additives Depending on the panel size, results cover common staples (gluten, dairy, eggs, soy, nuts) through to local Asian foods, additives, preservatives, and spices.
✓
Gut Barrier Panel (included in FIT 132 and FIT 176) IgG 1–4, C3d, and IgA 1–2 across three important gut gatekeeper markers, showing whether your gut barrier is intact, mildly compromised, inflamed, or severely leaky.
✓
Inflammation indicators The complement and immune complex data also act as a snapshot of systemic immune activation and food-driven inflammation.
✓
Custom 7-day meal plan (FIT 132 and FIT 176) A personalised meal plan created by KBMO’s nutrition team based on your specific results, accessible through the mobile app.
✓
Cross-reactivity guidance Details on which foods commonly cross-react with your trigger foods, plus safe alternatives and substitutes.
✓
Severity of gut dysfunction The Gut Barrier Panel allows your practitioner to differentiate simple sensitivity from inflammation through to severe leaky gut, directly guiding the depth of your gut healing protocol.

Together, these results pinpoint not just which foods you should eliminate but how severely your gut and immune system are reacting, and what is driving the sensitivities at a root-cause level. That is the foundation Dr. Menka uses to build your personalised elimination, rotation, and gut-healing plan.

What Our Customers Say

Frequently Asked Questions (FAQ)

Food sensitivity tests (KBMO / FIT) analyse multiple immune pathways from a finger-prick sample to give you a clear picture of which foods you may be sensitive to. The test is done through a simple finger prick, and the sample is sent to a lab for analysis. The panel can be tailored to your diet including common local foods in Singapore. After identifying your sensitivities, you can plan a targeted elimination diet to relieve your symptoms.

Food sensitivity tests identify “delayed” immune reactions through IgG antibody, C3 pathway, and immune complex measurement. Symptoms associated with food sensitivities surface with some time delay for example, bloating that appears hours after consuming the food. Allergy tests, in contrast, identify “immediate” allergic responses that can be life-threatening. Examples of immediate allergic reactions include hives and anaphylaxis.

FIT panels test 22, 132, or 176 foods and additives, including everyday staples like rice and common spices.

If left untreated, the gradual onset of symptoms over time may resemble IBS (Irritable Bowel Syndrome). Depending on how long digestion has been compromised, these symptoms could also cause systemic problems including fatigue, joint pain, and headaches ultimately leading to loss of energy and general wellness.

The FIT’s multi-pathway approach (IgG, immune complexes, complement activation, and gut barrier markers) is what minimises false positives, the main weakness of simpler IgG-only food sensitivity tests.

Results are typically available in approximately 3–4 weeks, delivered as a comprehensive report with sensitivity scores and a personalised meal plan.
