Allergy test (patch test/epicutaneous test)

Epicutaneous test is used in case of suspicion of allergy to substances that come into contact with the skin. Test material is placed in small chambers directly on the skin and is left untouched for 48 hours.
The test is read after 72 hours and the area is not washed until the test has been read.

Preparations at home before the test
For the last 2-3 weeks before the epicutaneous test, the skin on the back can not be lubricated with local steroids (cortisone ointments and creams for eczema). If you are taking Prednisolone tablets, your dermatologist will consider whether the test is still possible.

Consultation with a dermatologist

The dermatology class, including application of the test material, lasts about 20 minutes. Using a plaster, the test material is taped to the back. It rarely causes discomfort.

After the consultation

When the patch with the test material is on, you can not wash your back or sunbathe. Sweating from physical activity can cause the patch to loosen and should be avoided.

Avoid scratching the patch and wearing a top at night to prevent it from coming loose during sleep.

A new consultation is arranged with a dermatologist to read the test after 3 days. When the test has been read, you will receive information about whether allergies have been detected or not and possibly which product or products you should avoid coming into contact with and what kind of treatment is recommended.

Possible side effects

Epicutaneous tests rarely cause complications. In some cases, the reaction to the test material itself can cause a severe rash that can be lubricated with strong local steroids to reduce itching.

About contact dermatitis

Contact dermatitis is an inflammation of the skin that is triggered by either allergies or irritants. The area exposed to the irritant becomes red, swollen, gets blisters and possibly ulceration. It causes symptoms such as itching, burning and cracked skin. Most people get it on their hands, but it can also occur elsewhere on the body. About 5% suffer from contact dermatitis during their lifetime.

There are two types of contact dermatitis: contact allergic eczema and toxic eczema.

Contact dermatitis is a delayed type of hypersensitivity and the symptoms do not appear until 24 to 72 hours after exposure to the allergen and are often severely limited and improve within a few days.

In acute toxic eczema, the rash appears within minutes to hours after exposure to the irritating substance; if there is a mild irritation, the reaction may appear as late as days to weeks after exposure. The eczema is often more unclear in the delimitation and often takes weeks to get better.

The trigger for contact dermatitis can be a wide range of things. Some examples are nickel, cobalt and chromium, rubber chemicals, perfumes and plants. Toxic variant is often occupationally relevant and can be triggered by various chemicals and liquids.
