What this test is
This is a blood test that measures specific immunoglobulin E (IgE) antibodies directed against peanut proteins. Elevated levels may suggest sensitization to peanuts, but the test alone cannot diagnose an allergy or predict its severity. Results are interpreted by a clinician in the context of symptoms and exposure history.
What it measures
- Peanut-specific IgE — reflects the level of IgE antibodies directed against peanut proteins
- Total IgE — sometimes measured to provide context, though not specific to peanut allergy
- Component-resolved IgE (e.g., Ara h 1, Ara h 2, Ara h 3) — may help assess risk for severe reactions, but availability varies
What the test involves
A healthcare professional collects a small blood sample from a vein, usually in the arm, using a standard blood draw. The sample is then sent to a laboratory for analysis.
Why it is often ordered
A clinician may order this test when a person has a history of reactions after eating peanuts or peanut-containing foods, or when evaluating a suspected food allergy. It can also be used to monitor changes in sensitization over time, though it is not a substitute for a clinical evaluation.
Preparation
No special preparation is typically required for this blood test, but you should follow the specific instructions provided by the collection laboratory. This may include fasting or avoiding certain medications, so always confirm with the lab beforehand.
How results are reported
Results are reported as a numerical level of peanut-specific IgE, often with a qualitative interpretation such as negative, low, moderate, or high. Reference ranges and decision points vary by laboratory, so your clinician will interpret the results based on the lab's own ranges and your individual history.
Before you go
- Whether any medications or foods need to be avoided before the blood draw
- The lab's specific reference ranges and how results will be reported
- If the test includes peanut component testing or only whole peanut IgE
