What this test is
This test measures the amount of immunoglobulin E (IgE) antibodies that bind to hazelnut proteins in a blood sample. It is a type of specific IgE allergy blood test, sometimes called a component test when individual proteins are measured. Results are interpreted by a clinician alongside your symptoms and exposure history.
What it measures
- Hazelnut-specific IgE — reflects the amount of IgE antibody in your blood that binds to hazelnut proteins
- Total IgE (if included) — reflects overall IgE antibody level, which can be elevated in allergic conditions
- Component allergens (if performed) — reflect sensitization to specific hazelnut proteins that may relate to reaction patterns
What the test involves
A healthcare professional collects a small blood sample, usually from a vein in your arm, using a standard blood draw. The sample is sent to a laboratory for analysis, and no special preparation beyond the lab's instructions is typically needed.
Why it is often ordered
A clinician may order this test when someone reports symptoms such as hives, swelling, stomach upset, or breathing trouble after eating hazelnuts or foods that may contain them. It can also be used to help assess whether avoidance or further evaluation is appropriate.
Preparation
Follow the collection lab's instructions about medications, fasting, or timing. Because preparation can vary by lab and by the specific test method, confirm any details with the lab before your appointment.
How results are reported
Results are reported as a numeric value for hazelnut-specific IgE, often with a qualitative category such as negative, low, moderate, or high. Reference ranges and reporting formats differ by laboratory, so your clinician will interpret the result in the context of your symptoms and history.
Before you go
- Whether any medications or foods should be avoided before the blood draw
- How and when results will be shared with you and your clinician
- Whether the lab uses a specific reporting format or reference range you should know about
