Allergy Testing in Seoul: Patch, Prick and Blood Tests for Skin Allergies
Recurring rashes, hives or itching often have a trigger that can be identified. A dermatologist chooses the right test — patch, skin prick or blood IgE — based on your symptoms and explains the results in English.

Which allergy test do I need?
Patch testing identifies delayed contact allergies that cause dermatitis, while skin prick and blood IgE tests identify immediate allergies that cause hives, hay fever or food reactions. The right test depends on your symptoms, so a consultation comes first.
Test types
Allergy tests we use
Each test answers a different question.
Patch test
Finds contact allergens such as nickel, fragrance and hair dye; see contact dermatitis.
Skin prick test
Checks immediate allergies to dust mites, pollen, pets and some foods.
Specific IgE blood test
Useful when skin testing is not possible or antihistamines cannot be stopped.
Hives and rashes
Testing guided by history; see allergy rashes.
Hay fever rash
Seasonal skin flares; see hay fever rash.
Eczema
Selected patients benefit from testing; see eczema.
How it works
How patch testing works
Small amounts of common allergens are applied to the back under patches. The skin is checked at 48 hours and again at 72–96 hours, because contact allergy develops slowly.
- Day 1: patches applied
- Day 3: patches removed, first reading
- Day 4–5: final reading and explanation
- After: written list of allergens to avoid
