The levels of IgE Antibodies in the blood are computed when Allergy Orchard Grass test is performed on a sample of blood. It is performed to confirm the Orchard Grass Allergy. This particular allergy causes sneezing, runny or itchy nose, nasal congestion, itchy and watery eyes etc. Clinical manifestations of immediate hypersensitivity (allergic) diseases are caused by the release of proinflammatory mediators (histamine, leukotrienes, and prostaglandins) from immunoglobulin E (IgE)-sensitized effector cells (mast cells and basophils) when cell-bound IgE antibodies interact with allergen. In vitro serum testing for IgE antibodies provides an indication of the immune response to allergen(s) that may be associated with allergic disease. The allergens chosen for testing often depend upon the age of the patient, history of allergen exposure, season of the year, and clinical manifestations. In individuals predisposed to develop allergic disease(s), the sequence of sensitization and clinical manifestations proceed as follows: eczema and respiratory disease (rhinitis and bronchospasm) in infants and children less than 5 years due to food sensitivity (milk, egg, soy, and wheat proteins) followed by respiratory disease (rhinitis and asthma) in older children and adults due to sensitivity to inhalant allergens (dust mite, mold, and pollen inhalants).
No special preparation is needed for Allergy Orchard Grass Enzyme Assay. Inform your doctor if you are on any medications or have any underlying medical conditions or allergies before undergoing Allergy Orchard Grass Enzyme Assay. Your doctor depending on your condition will give specific instructions.
