Quick Intro

VEI Clinic Apgujeong is an English-friendly internal-medicine clinic offering targeted evaluations for food reactions—not one-size-fits-all “sensitivity” panels. We’re on the 3rd floor of Beneheim City, 162 Apgujeong-ro, a short walk from Apgujeong Station (Exit 5).

First, let’s define terms (so you get the right test)

• Food allergy (IgE-mediated) → fast reactions (minutes–2 hrs): hives, swelling, wheeze, vomiting, anaphylaxis.
• Non-IgE allergy / eosinophilic conditions → delayed GI/skin symptoms; needs specialist work-up.
• Food intolerance/sensitivity → non-allergic: e.g., lactose intolerance, FODMAP sensitivity, histamine intolerance, non-celiac gluten sensitivity, reflux, IBS. Tests and treatments differ.

We match the history + symptoms to validated tests and a usable plan. We do not sell broad “food IgG sensitivity” panels—they’re non-actionable and often misleading.

What We Test (tailored to your story—no junk panels)

• Allergy (when history suggests IgE)
• Specific IgE blood tests (same-day draw) to targeted foods.
• Skin-prick testing (by appointment/partner allergist).
• Oral food challenges coordinated with an allergist when appropriate.
• Celiac disease (autoimmune gluten reaction)
• tTG-IgA + total IgA (± DGP-IgG/EMA as indicated).
• HLA-DQ2/DQ8 typing and GI referral if needed.
• Guidance on not starting gluten-free before testing; if already GF, we’ll discuss a safe gluten challenge.
• Lactose intolerance / FODMAP-related symptoms
• Hydrogen breath testing (by appointment) for lactose; clinical trials of low-FODMAP diet with a dietitian.
• Rule-outs (iron, thyroid, celiac screen) if symptoms suggest.
• Histamine-related symptoms
• Symptom-driven elimination/re-challenge plan; meds review (e.g., alcohol/DAO interactions).
• We avoid unvalidated “DAO” quick fixes without context.
• Other GI causes to consider
• H. pylori, reflux, IBS, bile acid issues, post-infectious states—tested as indicated.

What We Avoid (and why)

• Indiscriminate “food sensitivity” IgG/IgG4 panels
• Hair analysis/live blood microscopy
  These often reflect food exposure—not intolerance, generate false “positives,” and lead to unnecessary restriction. We’d rather test things that change care.

Preparation (improves accuracy)

• Skin-prick allergy testing: stop antihistamines 3–7 days beforehand (we’ll give a safe list/timing). Do not stop essential meds unless a doctor tells you to.
• Celiac tests: stay on gluten before blood tests. If you’re already gluten-free, ask us about a gluten challenge schedule.
• Breath tests: arrive fasted; avoid antibiotics, probiotics, and vigorous exercise per our instructions.
• General: bring a food/symptom diary covering the last 2–4 weeks.

Visit Flow (Typically 30–60 min for consult + draw; breath/skin tests 60–90 min)

1. History mapping → timing, foods, portion sizes, symptom pattern, travel/meds.
2. Targeted plan → only tests that help decisions. Costs explained up front.
3. Testing → same-day blood draw; schedule breath/skin/patch tests if needed.
4. Results & plan → clear English summary: what to eat now, what to avoid, and how/when to re-introduce. Dietitian and allergist referrals arranged when helpful.

Safety: When to use emergency care (not an outpatient clinic)

Go to an ER for anaphylaxis signs: throat/tongue swelling, breathing trouble, wheeze, fainting, persistent vomiting, rapidly spreading hives with dizziness. If you carry epinephrine, use it as trained and call emergency services.

After-Care & Long-Term Plan

• Prefer short, supervised eliminations with structured re-challenges over permanent restriction.
• We aim for the least restrictive diet that controls symptoms.
• Written flare plan (OTC meds, rescue steps) and when to follow up.
• Optional dietitian support (low-FODMAP, balanced nutrition while traveling or working long hours).

What to Bring

• Photo ID (passport if visiting)
• Medication & supplement list
• Any prior labs or allergy reports
• A brief food/symptom diary with timing and portions

Related Services

• Hydration Support IV (if illness/fasting left you depleted)
• Travel Medicine (vaccines, titers, fit-to-fly)

FAQs

Should I buy a big “food sensitivity panel” online?
We don’t recommend it. Many panels measure IgG to foods, which reflects exposure, not intolerance—often not actionable and can cause unnecessary restriction.

Can I test for gluten problems if I’m already gluten-free?
Celiac tests work best while eating gluten. If you’re already GF, we’ll discuss a supervised gluten challenge or alternate pathways.

How long until I feel better?
With the right plan, some improve within 1–3 weeks; complex cases (IBS, reflux, celiac) follow longer timelines with stepwise adjustments.

Can you confirm lactose intolerance?
Yes—via hydrogen breath testing or a structured lactose trial with guidance.

Will I get results and instructions in English?
Yes. You’ll receive an English summary and practical next steps.
