Certain substances in the environment trigger an allergic reaction from our immune system. These substances, known as allergens, are not harmful. Dust, pollen, pet hair and specific foods are some examples of allergens that we encounter in our daily life.
Our immune system gets triggered by allergens because it considers these to be pathogens too. Common reactions include rashes, coughing, sneezing and other serious complications. It varies depending upon the allergen. Some allergens can trigger a severe allergic reaction which can turn to be life-threatening.
Most people consider these symptoms to be seasonal and tend to ignore or live with their allergies, but it is important to get an allergy test. This can determine the potential allergens that cause these reactions and prevent or minimise the symptoms.
In an allergy test, your blood sample is tested for immunoglobulins, the antibodies generated when our immune system encounters an allergen.
