Allergy changes over time

Allergy is constantly evolving and triggers and symptoms may change over time. In general, a toddler or a small child is exposed (and sensitive) to different allergens than the average adult. Regular testing and re-evaluation of the underlying allergy is necessary to tailor the treatment and possible avoidance advice.

In its early stages, allergy can appear as a seemingly harmless condition, such as hay fever during the pollen season. Some people gradually build up an allergic condition over several years before experiencing any symptoms. Others experience sudden, life-threatening anaphylactic reaction following ingestion of a certain food, drug, or an insect bite. Additionally, some allergies that start as eczema or gastrointestinal problems can evolve into asthma, frequently involving respiratory symptoms such as hyper reactivity and obstruction of the airways.

Allergy March – keep track of a changing allergy

Allergy undergoes dynamic changes over time, and the term "Allergy March" is often used to describe this characteristic disease progression. During a typical Allergy March sequence, sensitization and visible symptoms generally:

  • appear during specific age intervals
  • persist over a number of years
  • tend to spontaneously decrease with age

Regular follow up testing with ImmunoCAP blood test

As allergy is constantly evolving, an ImmunoCAP blood test taken at one specific time will only show the disease status at that particular moment. Regular testing of specific allergens at given intervals of time will provide the information needed to accurately follow disease development.

Regular follow-up with ImmunoCAP will help you determine:

  • if allergies have been outgrown and if allergen avoidance or treatment is no longer needed
  • if new allergies have developed and if new allergen avoidance advice or treatment is necessary

Consequently patient well-being can be optimized over time.
