Order Beta Lactoglobulin (BLG) Allergy TestThe Beta Lactoglobulin (BLG) Allergy Test measures specific IgE antibodies directed against beta-lactoglobulin, a whey protein found in cow's milk. Because BLG is one of the most abundant proteins in whey, sensitization to it is often considered when cow's milk allergy is suspected. This test provides an objective, blood-based assessment that complements a clinical history rather than replacing it.
About Beta Lactoglobulin (BLG) Allergy Test in Appleton
Beta-lactoglobulin is a lipocalin-family protein that binds small hydrophobic molecules and is present in the whey fraction of milk from ruminants.
In cow's milk, proteins are divided broadly into caseins and whey proteins. Beta-lactoglobulin is the principal whey protein in bovine milk and is absent from human milk, which is one reason it is studied as a marker of cow's milk sensitization.
An IgE allergy test detects antibodies that bind to a specific allergen. A measurable level of beta-lactoglobulin-specific IgE indicates that the immune system has produced antibodies to this protein, but the result must be interpreted alongside symptoms and exposure history because sensitization and clinical allergy are not identical.
Beta-lactoglobulin is heat-labile to varying degrees and may behave differently in baked or extensively processed milk products compared with raw milk. This is one reason clinicians often combine component testing with whole-milk IgE results and a careful dietary history.
