Order Casein Allergy Test | Milk AllergyA casein allergy test is a blood-based immunoassay that measures specific IgE antibodies directed against casein, the dominant protein fraction in cow's milk. Because casein accounts for roughly 80 percent of the total protein in cow's milk, it is one of the most clinically relevant targets when evaluating a suspected milk allergy. The test is used to help distinguish a true immune-mediated reaction from other causes of milk intolerance, such as lactose malabsorption.
About Casein Allergy Test | Milk Allergy in Rochester
Casein is not a single molecule but a family of related phosphoproteins, and it behaves differently from the whey proteins that make up the remainder of cow's milk.
Casein is a family of phosphoproteins that makes up about 80 percent of the protein in cow's milk, with the remainder composed largely of whey proteins such as beta-lactoglobulin and alpha-lactalbumin. The caseins are heat-stable, which is one reason milk-allergic individuals may still react to baked or extensively heated milk products that would otherwise degrade whey proteins.
An IgE-mediated milk allergy involves antibodies that bind to casein and trigger the release of histamine and other mediators from mast cells. Symptoms can appear within minutes to a couple of hours after exposure and may involve the skin, gastrointestinal tract, or respiratory system. Because casein is present in many processed foods, identifying it as the specific trigger can meaningfully change how a person manages their diet.
Testing for casein-specific IgE is typically ordered alongside other milk protein components to build a fuller picture of sensitization. Results are reported as a quantitative antibody level and are interpreted by a clinician in the context of the person's history, since sensitization on a blood test does not by itself confirm a clinical allergy.
