How Nut Allergy Blood Tests Work
Nut allergy blood tests, also known as allergy blood tests for nuts or nut allergy tests, measure the presence of immunoglobulin E (IgE) antibodies to specific nuts in your blood. These antibodies are produced by your immune system in response to exposure to nut proteins. By detecting the levels of these IgE antibodies, the blood test can determine whether you have an allergy to nuts and which specific nuts you are allergic to.
The process of nut allergy blood testing involves drawing a small sample of your blood, usually from a vein in your arm. The blood sample is then sent to a laboratory, where it is analyzed for the presence of IgE antibodies to different types of nuts. The results are typically reported as numerical values, indicating the amount of IgE antibodies detected for each nut.
It’s important to note that nut allergy blood tests have some advantages over other allergy testing methods. Unlike skin prick tests, blood tests are not affected by antihistamines and can be performed even if you have extensive rashes. Additionally, blood tests are more accurate in diagnosing food allergies compared to other tests, such as IgG or IgG4 testing, which are not recommended for diagnosing allergies. However, it’s crucial to interpret the results in the context of your medical history and consult with an experienced allergist who can provide guidance based on their knowledge of different scoring systems or units used by laboratories.
| Nut | IgE Antibody Level |
|---|---|
| Peanuts | High |
