IgG4 Chronic Food Sensitivity (88 Items)
The full version of the 22-item panel, covering 88 everyday foods across dairy and eggs, meat, seafood, legumes and nuts, grains, roots and tubers, vegetables and fruit, and seasonings and drinks. When your diet is varied and the basic panel can't find the culprit, coverage is what matters.
Worth testing if:
- You have already done the basic panel and still cannot identify the trigger food
- You eat out often and your diet is highly varied
- Chronic gastrointestinal symptoms lasting more than three months
- You want to audit the full food list in one go before making adjustments

What this test is for
An IgG4 assessment of your reactions to common foods identifies the dietary triggers that may sit behind chronic inflammation and leaky gut, so diet can be adjusted and the gut given a chance to repair.
Eggs were once the protein Shohei Ohtani ate at every meal. But according to Japanese media reports, he later found that eating eggs left him feeling unwell and affected his recovery from training. After assessment by his nutrition team, he decided to drop omelettes and other high-egg products in favour of choices better suited to his own body.
Rather than passively eating the wrong things and taking the damage, use data to work it out: which foods can your gut still handle right now? Which ones should pause for a while so your body can repair? This test helps you rebuild trust with your body — eating with more confidence, and with more strategy

Frequently asked questions
Does IgG mean allergy? Will I end up unable to eat anything?
IgG4 testing is not about immediate allergy (that is IgE) — it is about a loss of immune tolerance from chronic exposure. What matters isn't banning foods, but rotating them strategically, pausing some for a while, and repairing the gut barrier
Isn't IgG4 alone inaccurate — shouldn't total IgG be measured for completeness?
IgG4 is the tolerance-type immune response produced by long-term repeated exposure, so it speaks more directly to the mechanisms behind chronic inflammation and leaky gut. Total IgG covers IgG1 to IgG4 across many categories, which sometimes reacts too broadly, produces more false positives, and ends up misleading
