Allergen, Food, Milk (Cow's) Components IgE
Also known as: MILK COMP
Use
The Allergen, Food, Milk (Cow's) Components IgE test measures specific IgE antibodies to milk components. It helps in the diagnosis of milk allergy by identifying specific protein components of milk that trigger allergic reactions. The test assesses the immune response to alpha-lactoalbumin, beta-lactoglobulin, and casein, which are proteins found in cow’s milk. The results aid clinicians in understanding the potential for IgE-mediated reactions and contribute to the overall allergy assessment, helping to determine appropriate dietary and treatment plans for patients with suspected milk allergies.
Special Instructions
Not provided.
Limitations
The test detects IgE antibodies to specific milk components, but the presence of these antibodies alone does not confirm clinical allergy. The concentrations of allergen-specific IgE may not directly correlate with clinical symptoms or skin test results. A negative result does not exclude the possibility of a clinical allergy or anaphylaxis. Results should be correlated with clinical history and in vivo reactivity to specific milk allergens.
