Description
The Peanut Allergy IgE Blood Test measures the level of peanut-specific IgE antibodies in your blood. Elevated levels may indicate a peanut allergy, which can trigger mild to severe reactions ranging from skin irritation and digestive issues to anaphylaxis.
This test is a safe, non-invasive alternative to skin prick testing and is ideal for individuals with suspected peanut sensitivity or a history of allergic reactions.
What This Test Measures
- Immunoglobulin E (IgE) antibodies specifically targeting peanut proteins.
- A higher IgE level suggests the immune system is reacting abnormally to peanuts.
- Helps identify the likelihood and severity of an allergic reaction.
Why This Test May Be Ordered
Your provider may recommend this test if you or your child experiences:
- Hives, rash, or itching after eating peanuts
- Nausea, vomiting, or abdominal pain linked to peanut consumption
- Swelling of the lips, tongue, or throat
- Difficulty breathing or wheezing after peanut exposure
- Family history of food allergies
- Monitoring or confirmation of known peanut allergy
