Beta Lactoglobulin (BLG) Allergy Test in Aurora, IL

About Beta Lactoglobulin (BLG) Allergy Test in Aurora

Beta-lactoglobulin is a whey protein found in the milk of cows and other ruminants, and it is one of the most common triggers of cow's milk allergy.

Cow's milk contains two main protein groups: caseins and whey proteins. Beta-lactoglobulin belongs to the whey fraction and is present in substantial amounts in cow's milk and in whey-based ingredients. Because it is not found in human breast milk, it is often the first foreign milk protein an infant encounters.

An immune response to beta-lactoglobulin is mediated by IgE antibodies, the same class of antibodies involved in many immediate allergic reactions. Sensitization to this protein can occur alongside reactions to other milk allergens, such as alpha-lactalbumin and casein, so testing for beta-lactoglobulin is typically interpreted in the context of a broader allergy evaluation.

The test uses a blood sample to detect beta-lactoglobulin-specific IgE. Results are reported as a numerical level or a class score, and they are intended to support, not replace, a clinical assessment. A healthcare professional can explain what a given result means in relation to symptoms, history, and other test findings.
