ALLERGY TEST

An allergy is an immune system response to a substance, known as an allergen, that is typically harmless to most people. Common allergens include pollen, certain foods, insect stings, and pet dander. When an allergic person comes into contact with an allergen, their immune system overreacts, leading to symptoms such as sneezing, itching, and respiratory issues.

How allergies occur

An allergy is an immune system response to a substance, known as an allergen, that is typically harmless to most people. Common allergens include pollen, certain foods, insect stings, and pet dander. When an allergic person comes into contact with an allergen, their immune system overreacts, leading to symptoms such as sneezing, itching, and respiratory issues.

What Triggers Allergic Reactions?

Allergies occur when the immune system reacts excessively to substances that are usually harmless, such as pollen, dust mites, or certain foods. This exaggerated response involves the release of histamines and other chemicals, leading to allergy symptoms.

IgE antibodies and Allergic Reactions

When exposed to allergens, such as pollen or certain foods, mast cells release granules containing chemicals like histamine. IgE antibodies, specific to each allergen, attach to mast cells, triggering the release of these chemicals. The chemicals cause allergy symptoms, ranging from mild itching to severe reactions. Understanding this immune response is crucial in diagnosing and managing allergies effectively.
