What Does This Test Measure?
The test detects specific IgE antibodies in your serum that target common food allergens. IgE is a type of antibody that the immune system produces in response to allergens, which can trigger allergic reactions.
Why Might You Need This Test?
Your healthcare provider may recommend this test if you have symptoms like hives, swelling, difficulty breathing, or digestive issues after eating certain foods, or if you suspect a food allergy based on your medical history.
How Is the Test Performed?
A blood sample is drawn from a vein in your arm. The sample is sent to a lab where it is analyzed using an immunoassay method to detect IgE antibodies against specific allergens.
What Are the Possible Results?
Results will show whether you have IgE antibodies against the tested allergens. Positive results suggest a potential allergic reaction to those foods, but they do not confirm a diagnosis alone. Further evaluation by an allergist may be needed.
Clinical interpretation
How abnormal results are interpreted and what conditions they suggest.
This test plays a key role in identifying potential food allergies by measuring IgE antibodies. It can help guide dietary adjustments or referrals to an allergist for more detailed testing and management strategies. Results should be interpreted by a healthcare provider in the context of your symptoms and medical history.
