What is the purpose of this test?
Order this English Plantain Allergy IgE Blood Test, which measures the IgE antibody levels in the blood to detect an allergy to English plantain. English plantain, also known as Plantago lanceolate, is a type of plant in the Plantaginaceae family. It is a weed that grows yearly and can be found in humid meadows and along roadsides. Plantain is a common cause of pollinosis in moderate climates and has two allergens, Pla l 1 and Pla l 2. Pla l 1 is a key allergen that helps diagnose plantain pollen sensitivity. Pla l 2 is a small protein that can cause polysensitization. Plantain allergy can cause seasonal allergic rhinitis, rhino-conjunctivitis, and sometimes asthma. It is important to note that plantain allergen can also cross-react with other pollens such as grass, birch, ash, and olive pollen.
What causes an allergy to English plantain?
English plantain allergies are triggered by a hypersensitive individual inhaling its pollen. These allergens may trigger a response in their immune system since the body views certain substances as harmful, producing IgE antibodies to combat these invaders. Unfortunately, these antibodies cause histamine to be released, resulting in the symptoms associated with an allergic reaction.
