Inhalant Allergy Panels -IgE

Inhaled allergens are substances in the environment that, when inhaled, can trigger allergic reactions in individuals who are sensitive to them. These allergens are typically harmless to most people but can cause a range of symptoms and health issues in those with allergies. Common inhaled allergens include pollen, dust mites, pet dander, and mould spores. Understanding these allergens and their effects is so important for people who are more susceptible to reacting.  

Types of inhaled allergens 

Pollen 

Pollen allergies, often referred to as hay fever or allergic rhinitis, are

highly seasonal. Pollen is a common inhaled allergen produced by

plants for reproduction. Trees, grasses, and weeds release pollen

grains into the air, where they can be inhaled by individuals with

allergies.

Dust mites 

Dust mites are microscopic insect-like pests that thrive in household dust. They feed on dead skin cells and are commonly found in bedding, carpets, and upholstered furniture. When their faeces and body fragments become airborne, it can trigger a reaction in those who are allergic.

Pet dander

 consists of tiny particles of skin flakes, saliva, and urine from cats, dogs, and other animals with fur or feathers. 

Pet dander can create an allergic reaction in individuals who are sensitive to it.

Mould spores 

Mould spores thrive in damp and humid environments. They can be found both indoors and outdoors and often grow in places with a lot of moisture, such as around leaks in roofs or windows or where there has been flooding. Inhaling mould spores can lead to various health issues, including allergic reactions, respiratory problems, and fungal infections.

How inhaled allergens trigger allergic reactions 

When inhaled allergens enter the body, the immune system recognises them as foreign invaders and produces antibodies . Allergic reactions specifically trigger an antibody called immunoglobulin E (IgE). 1  

The IgE antibodies are triggered when you are first exposed to an allergen release of histamine and other chemicals. Histamine is responsible for many allergy symptoms, such as sneezing, itching, and congestion. 

Importance of identifying specific allergens 

Identifying the specific inhaled allergens responsible for an individual's

symptoms is crucial for developing an effective allergy management

plan. It allows for targeted allergen avoidance and, if necessary, the

initiation of allergen-specific treatment .
