Order Casein Allergy Test | Milk AllergyCasein is the dominant protein in cow's milk, accounting for roughly 80 percent of its total protein content. An allergy to casein is an immune response mediated by immunoglobulin E (IgE), the antibody class responsible for immediate allergic reactions. This test measures casein-specific IgE in a blood sample to help determine whether a person's symptoms are consistent with a milk allergy.
About Casein Allergy Test | Milk Allergy in Westminster
Casein allergy testing detects IgE antibodies that recognize casein, the main protein fraction in cow's milk.
Cow's milk contains two principal protein groups: caseins, which make up about 80 percent of the total protein, and whey proteins, which account for the remainder. Casein itself is not a single molecule but a family of related proteins, including alpha-s1, alpha-s2, beta, and kappa casein. Because casein is heat-stable, it survives cooking and processing, which is why some individuals with a casein allergy react to baked goods and other heated milk products.
An IgE-mediated milk allergy occurs when the immune system mistakenly identifies casein as a threat and produces antibodies against it. On subsequent exposure, these antibodies trigger the release of histamine and other mediators from mast cells, producing symptoms that can include hives, itching, swelling, vomiting, diarrhea, and in severe cases, anaphylaxis. Symptoms typically appear within minutes to a couple of hours after ingestion.
The test uses a blood sample to quantify casein-specific IgE. Results are reported as a numerical value, often in kilounits per liter (kU/L), and are interpreted alongside a person's clinical history. A positive result indicates sensitization to casein, meaning IgE antibodies are present, but it does not by itself confirm that casein is causing symptoms. A negative result makes an IgE-mediated casein allergy less likely. Because interpretation depends on the full clinical picture, results should be reviewed with a qualified healthcare professional.
