Bloating, fatigue, skin flare-ups or brain fog after eating can point to a food sensitivity or allergy — but which food, and which type of immune response, isn't something you can work out by guessing. Food sensitivity testing (IgG/IgA) looks at delayed reactions; allergy testing (IgE) looks at immediate reactions.
IgE testing looks for immediate-type allergic reactions — the kind that can cause hives, swelling or breathing symptoms within minutes of exposure to a food or airborne allergen like pollen, dust mites or animal dander.
IgG/IgA testing looks for delayed-type food sensitivities — reactions that build up over hours or days and are more often linked to bloating, fatigue, skin flare-ups, headaches or brain fog than to an acute allergic reaction.
These are genuinely different tests looking at different parts of your immune system, which is why we offer both — your practitioner will help you decide which one (or which combination) fits your symptoms.
We offer both, and they answer genuinely different questions — neither replaces the other.
Looks at your genetic blueprint to show what your body is generally predisposed to react to or struggle processing — for example, a genetic reduced capacity to break down lactose or histamine. This is fixed from birth and doesn't change over time, no matter what you're currently eating.
Measures your immune system's actual current antibody response to specific foods or allergens you've been exposed to. This can change over time as your diet, gut health and exposure change — it shows what's happening now, not a lifelong predisposition.
In short: FitGenes tells you what your genes suggest you might struggle with in general. IgG/IgA/IgE testing tells you what your immune system is actually reacting to right now. Many patients benefit from both — your practitioner can explain how the two fit together for your situation. See our Genetic Testing page for the FitGenes food intolerance report.
Four panels covering different combinations of foods, airborne allergens, and sensitivity types.
| Test | Collection | Also Includes | Best If You Also Want | Sample Report |
|---|---|---|---|---|
| 50 Inhalant Panel + Total IgE | Blood draw or blood spot card* | Immediate-type (IgE) allergy screening across 50 common airborne allergens, grouped by grasses, trees, weeds, moulds, and miscellaneous (pet dander, dust mites, cockroach, house dust) — plus a Total IgE marker. | To check whether hay-fever-type symptoms (sneezing, congestion, itchy eyes) are allergy-driven, rather than food-related. | 📋 View |
| 96 General Food Panel: IgA/IgG | Blood draw or blood spot card* | Delayed-type (IgG and IgA) sensitivity screening across 96 foods — dairy, grains/legumes/nuts, vegetables, fish/crustacea/mollusk, egg/meat/poultry, fruits, herbs/spices, and a Candida screen. | A broad first-look food sensitivity screen without needing the largest available panel. | 📋 View |
| 144 Food Panel: IgA/IgG | Blood draw or blood spot card* | A broader delayed-type food sensitivity screen, covering 144 individual foods across dairy, egg/meat/poultry, vegetables, herbs/spices and more. | A wider food sensitivity picture than the 96-food panel, for when more suspected trigger foods need checking. | 📋 View |
| 240 Food Panel: IgA/IgG | Blood draw or blood spot card* | The most extensive delayed-type food sensitivity screen we offer, covering 240 individual foods. A standalone panel — not combined with the 96 or 144 food panels, though the Inhalant Panel can be added on top. | The single most comprehensive food sensitivity picture available, for the widest possible range of suspected trigger foods. | Sample report coming soon |
| 96 General Food Panel: IgA/IgG + 27 Food Panel + Total IgE | Blood draw only | The full 96-food delayed sensitivity panel plus a 27-allergen immediate (IgE) panel and Total IgE marker, combined in a single test. | Both delayed food sensitivity and immediate allergy markers covered in one sample, rather than booking two separate tests. | 📋 View |
Current testing fees are listed on our prices page.
*Blood spot card (at-home finger-prick collection) carries no extra fee. Choosing a venous blood draw instead adds a lab collection fee — confirmed with your practitioner at booking.
Most panels on this page can be collected either way — pick whichever suits you better.
A simple finger-prick sample collected at home using a card kit, then mailed to the lab. No extra collection fee. Not available for the combined 96 General Food + 27 Food/IgE panel.
A standard venous blood draw at a collection centre. Carries an additional lab collection fee on top of the test price. Required for the combined 96 General Food + 27 Food/IgE panel.
