Order Alfalfa Allergy TestAn Alfalfa Allergy Profile measures the amount of immunoglobulin E (IgE) antibodies in the blood that react to alfalfa. IgE is the class of antibody the immune system produces in response to substances it identifies as threats. When those antibodies bind to alfalfa proteins, they can trigger the release of histamine and other chemical mediators from immune cells, which produces the symptoms associated with an allergic reaction.
About Alfalfa Allergy Test in O'fallon
Alfalfa is a perennial flowering plant in the legume family, widely cultivated as livestock feed and also consumed by people in the form of sprouts, leaves, and teas.
Because alfalfa belongs to the legume family, people with sensitivities to other legumes may sometimes react to it as well. Alfalfa sprouts and seeds are the forms most often linked to allergic reactions, and symptoms can range from mild oral itching and hives to nasal congestion, wheezing, or gastrointestinal discomfort.
The blood prick method used for this profile is a type of specific IgE testing. A small blood sample is collected and exposed to alfalfa allergen in the laboratory, and the amount of IgE that binds to the allergen is measured. This approach differs from skin prick testing, which introduces allergen extract into the skin and observes the resulting wheal and flare response.
Results are reported as a quantitative value that is compared against the laboratory's reference range. A detectable level of alfalfa-specific IgE indicates sensitization, meaning the immune system has produced antibodies to alfalfa. Sensitization does not by itself confirm that a person will experience symptoms, so results are interpreted alongside clinical history and other findings by a qualified healthcare professional.
