The consultation

Seeing an allergist in Brussels

The allergist is the specialist of allergies. At CIRCAE, in Woluwe-Saint-Lambert (Brussels), Dr Matthieu Desplan, pulmonologist and allergist, carries out the allergy work-up thanks to an on-site laboratory: skin-prick tests and a blood test measuring specific IgE, often in a single visit.

The consultation is for anyone with rhinitis, allergic asthma, conjunctivitis or symptoms linked to pollens, dust mites or animals, or simply wishing to identify the cause of their reactions. It leads to a clear plan: avoidance measures, treatment and, where indicated, desensitisation (allergen immunotherapy).

Areas

What the allergist manages

The main allergies diagnosed and followed at the centre.

Allergic rhinitis

Pollens & dust mites

Sneezing, blocked or runny nose, itching: identification of the allergens involved and tailored treatment.

Allergic asthma

Allergy & breathing

Asthma triggered by allergens: a combined work-up of allergy and lung function (FeNO, spirometry).

Allergic conjunctivitis

Eyes

Red, itchy and watery eyes, most often associated with allergic rhinitis.

Dust mites, pollens, animals

Airborne allergens

Identification of the most common airborne allergens and an everyday avoidance strategy.

Seasonal allergies

Pollens

Hay fever: symptoms linked to tree, grass or weed pollens depending on the season.

Desensitisation

Immunotherapy

Where indicated, a background treatment aiming to lastingly reduce the allergic reaction.

The technical suite

The allergy work-up

The consultation is supported, as needed, by allergy tests carried out in the on-site laboratory: skin-prick tests and a blood test.

First allergy consultation

Consultation · Allergist

A detailed history of the symptoms and context, then the choice of the most relevant tests.

  • Analysis of symptoms (rhinitis, asthma, conjunctivitis, breathing discomfort)
  • Context of onset (season, place, animals, environment)
  • Personal and family history of allergy
  • Clinical examination
  • Choice of skin-prick tests and/or a blood test

Allergy skin-prick tests

Allergy · Gold-standard diagnosis · On site

Drops of allergens are placed on the skin of the forearm, with a reading after 15 to 20 minutes. Performed in the on-site laboratory.

  • Pollens, dust mites, animal dander, moulds
  • Reading in mm, painless or barely painful

Indications

  • Allergic rhinitis and asthma
  • Allergic conjunctivitis
  • Assessment before desensitisation

Blood test: specific IgE

On-site laboratory · Blood test

Measurement of IgE antibodies directed against a specific allergen. Useful when skin-prick tests are not feasible (reactive skin, antihistamine treatment in progress).

  • Measurement of total and specific IgE
  • An alternative or complement to skin-prick tests
  • No need to stop antihistamines

Exhaled nitric oxide measurement (FeNO)

Simple examination · Allergic asthma

A non-invasive marker of allergic bronchial inflammation. A quick, painless examination.

  • Aids the diagnosis of allergic asthma
  • Assessment of airway inflammation
  • Monitoring the effectiveness of treatment

Frequently asked questions

The allergy work-up in practice.

What is the difference between skin-prick tests and a blood test ?
Skin-prick tests place drops of allergens on the skin and are read within 15 to 20 minutes. The blood test measures specific IgE in the laboratory. At CIRCAE, both are performed on site and are often complementary.
Do I need to stop my medication before a skin-prick test ?
Yes, antihistamines usually need to be stopped a few days before a skin-prick test (your doctor will specify how long, depending on the medication). No interruption is needed for the blood test.
Is the allergy work-up painful ?
Skin-prick tests are barely painful: a light, superficial prick of the skin. The blood test is a standard blood draw.
Does Dr Desplan offer desensitisation ?
Yes. Allergen immunotherapy (desensitisation) is offered where indicated, after the allergy work-up.
How do I book an appointment with the allergist at CIRCAE ?
