Order Beta Lactoglobulin (BLG) Allergy TestThe Beta Lactoglobulin (BLG) Allergy Test measures specific immunoglobulin E (IgE) antibodies in the blood that react to beta-lactoglobulin, a principal whey protein found in cow's milk. This test is used to evaluate sensitization to one of the most common milk allergens and can help clarify whether a milk-related reaction has an allergic basis.
About Beta Lactoglobulin (BLG) Allergy Test in Salem
Beta-lactoglobulin is a major allergen in cow's milk and whey.
Beta-lactoglobulin (BLG) is a whey protein that accounts for a substantial portion of the protein content in cow's milk. It is absent from human milk, which is one reason it is frequently implicated in cow's milk allergy, particularly in infants and young children.
The test detects allergen-specific IgE antibodies directed against BLG. A positive result indicates that the immune system has produced IgE that binds to this protein, which is a hallmark of allergic sensitization. However, sensitization does not always equate to clinical allergy, so results are interpreted alongside symptoms and exposure history.
Because BLG is present in whey and in many dairy-derived ingredients, identifying reactivity to this specific protein can be useful when evaluating reactions to milk, whey-based products, or foods that contain milk proteins. The test does not diagnose lactose intolerance, which involves a different mechanism.
