Order Beta Lactoglobulin (BLG) Allergy TestThe Beta Lactoglobulin (BLG) Allergy Test measures specific IgE antibodies against beta-lactoglobulin, a principal whey protein found in cow's milk. This blood-based assay helps identify an immune response to a major milk allergen, providing objective information that complements a clinical history.
About Beta Lactoglobulin (BLG) Allergy Test in Altadena
Beta-lactoglobulin is one of the most abundant proteins in whey and a well-recognized allergen in cow's milk.
Cow's milk contains casein and whey proteins; beta-lactoglobulin is a dominant whey fraction and a frequent target of IgE-mediated reactions. Because it is heat-sensitive to varying degrees, some individuals tolerate extensively heated milk while still reacting to raw or lightly processed dairy.
The test detects circulating IgE antibodies that bind beta-lactoglobulin. A positive result indicates sensitization to this protein, which may or may not correspond to clinical symptoms. Interpretation should always consider the patient's history, other milk components such as alpha-lactalbumin and casein, and the broader allergy workup.
Cross-reactivity is possible with milk from other mammals, though the degree varies by species. Beta-lactoglobulin is absent from human milk, which is one reason cow's milk-based formulas can provoke reactions in susceptible infants and children. Repeat testing may be useful when symptoms change or when dietary elimination is being reassessed.
