Science & Technology

The allergy your standard test will never find.

IgG-mediated delayed food allergies are real, measurable, and deeply connected to chronic symptoms. Here's how the science works.

What Is IgG?

Your immune system keeps a memory of everything you eat.

IgG (Immunoglobulin G) is your immune system's most abundant antibody — part of your long-term immune memory. When your immune system treats a food protein as a threat, it produces IgG antibodies against it. These antibodies form complexes with food particles, circulate in your bloodstream, and deposit in tissues — triggering inflammation wherever they land.

That inflammation doesn't always show up in the same place. In your gut: bloating, cramps, altered bowel movements. In your head: migraines, brain fog. On your skin: acne flares, eczema, psoriasis. In your joints: stiffness, aching. In your energy: fatigue that no amount of rest fixes.

IgE vs IgG

Why your standard allergy test misses this.

Most people know IgE allergies — the fast, dramatic reactions to peanuts or shellfish. IgG is completely different.

IgE Allergy (Classic / Immediate)
1
When it happens: Within minutes of eating. Unmistakable, fast-onset reaction.
2
Symptoms: Hives, swelling, anaphylaxis, immediate stomach pain.
3
How common: ~2–3% of adults. Relatively rare.
4
Standard test finds it: Yes — skin prick test and IgE blood test are effective.
5
Management: Strict lifelong avoidance + emergency medication (EpiPen).
🕐 IgG Allergy (Delayed / Hidden)
1
When it happens: 2 to 72 hours later. By then, you've had several more meals.
2
Symptoms: Bloating, fatigue, headaches, skin flares, joint pain, brain fog.
3
How common: Estimated 30–40% of people have significant IgG reactions.
4
Standard test finds it: No. Requires a specific IgG ELISA blood test.
5
Management: Personalised elimination + rotation diet based on results.
The Technology

ELISA — the gold standard in immunological diagnostics.

Every ImuPro test uses ELISA (Enzyme-Linked Immunosorbent Assay) technology on certified RIDASCREEN® plates manufactured by R-Biopharm AG. Your serum is tested against up to 270 food antigens, and the results are quantified precisely — not estimated.

1

Your serum is applied to RIDASCREEN® plates coated with food antigens

2

IgG antibodies in your serum bind to any food antigens they recognise

3

An enzyme-linked antibody is added and binds to any IgG present

4

A colour reaction is triggered — the intensity indicates the IgG level for each food

The result is a precise, quantified IgG reading for each food — not a yes/no, but an actual level. This is what makes the ImuPro report actionable: you know not just which foods to avoid, but by how much.

Certifications

Quality you can verify.

ISO 9001 — Quality management system certification ensuring consistent, reliable processes throughout manufacturing and testing.

ISO 13485 — The international standard for medical device quality management. This means ImuPro's test components meet the same quality requirements as surgical equipment — not casual lab work.

IVD-CE Approved — All reagents are approved as In Vitro Diagnostic devices under European regulations, confirming their suitability for clinical diagnostic use.

Your body has been sending signals.
It's time to finally listen.

Every day you wait is another day eating foods that may be silently inflaming your body. One blood test. Life-changing clarity. Book your ImuPro test today.
