What this test is
This is a blood test that measures immunoglobulin E (IgE) antibodies specific to chestnut. IgE antibodies are part of the immune system and can be linked to allergic reactions. The test is often used along with your symptom history and other allergy tests.
What it measures
- Chestnut-specific IgE — Reflects immune system sensitization to chestnut proteins
- Total IgE — Sometimes measured to help interpret allergy test results
- Other nut-specific IgE — May be tested together to check for related allergies
What the test involves
A healthcare professional collects a small blood sample, usually from a vein in your arm. The sample is sent to a laboratory for analysis.
Why it is often ordered
A clinician may order this test if you have had symptoms such as hives, itching, or stomach upset after eating chestnuts or foods containing them. It can also be part of a broader evaluation for nut allergies when chestnut exposure is possible.
