Allergy - Walnut Test

Walnut Allergy test is conducted on a sample of blood in order to test whether or not you are allergic to walnut. The test is used to detect the amount of IgE Antibodies in the blood which indicates the allergic level. In case you are allergic, you will develop symptoms such as abdominal pain, wheezing, nasal congestion, diarrhea, nausea amongst others whenever you’ll consume walnuts. It might in severe and rare cases cause Anaphylaxis which can be life- threatening. Thus, this test helps to diagnose the severity of the allergy that you might have with walnuts and their consumption. In alternate cases, this test might also be done through the process of skin pricking but it is rare and not very preferred.

It is recommended that you should either wear a sleeve-less or a short-sleeved shirt. Wearing a shirt with full- sleeves that can easily be rolled-up is also fine. You will not be expected to disturb your diet routine before the test. You can eat and drink as per your normal routine. However, if the sample taken is also to be used for further different tests, the doctor will inform you in advance. In that case, you might be advised to not eat for a few hours. Always follow the particular instructions given to you by the lab for the successful completion of the test.

As mentioned above, this test is useful in detecting whether or not you are allergic to walnuts. It also gives the doctors an accurate indication as to how severe the allergy is in you. The timely conduction of this test will help you to cure the allergy and also to avoid severe situations such as Anaphylaxis that can be fatal.

This test can be conducted at registered labs and infirmaries apart from the hospitals. For the test,
one or two teaspoons of a blood sample would be obtained directly from you.
• An alcohol pad is used to clean the skin.
• A needle is then injected through the part of rinsed skin into to your vein; specifically in
the one that can be seen from the skin.
• The blood is dragged out from the needle by a nozzle, saved in a vessel and sealed with
your name.
• This sample is then carried to the research laboratory for examination.
• It might takes 2-3 days or more for the test results to be declared.
