What this laboratory test evaluates
Cow's Milk (f2) IgE
The test measures an individual's allergic reaction to cow's milk by quantifying IgE antibodies. This test is performed in a lab and helps in diagnosing food allergies when combined with other clinical evaluations.
Who might need this test?This test is particularly useful for individuals who cannot undergo skin allergy tests due to reasons such as widespread skin disease, recent use of antihistamines, uncooperative behavior, or a high risk of severe allergic reactions.
Understanding Your Results:A positive result indicates sensitivity to cow's milk but does not confirm an allergy. Many people sensitized to cow's milk do not experience symptoms upon consumption. A thorough evaluation by a healthcare provider is essential for a proper diagnosis of food allergy. This test is a tool to identify sensitization, but a detailed medical history and clinical evaluation are necessary to diagnose IgE-mediated food allergies.
What type of sample is required for this test?0.3 mL serum.
