Lactalbumin beta Ab.IgE

This test detects IgE antibodies against beta-lactalbumin, a protein found in cow's milk. A positive result indicates a milk protein allergy, which is distinct from lactose intolerance. Symptoms of milk protein allergy can range from mild (itching, hives) to severe (anaphylaxis). This test is particularly important for infants and young children, but adults can develop milk allergies too. Identifying this specific milk protein helps guide dietary avoidance and treatment decisions.
