Cashew nut IgE level test is a blood test that measures the amount of a specific antibody called IgE in your blood, which is related to an allergic reaction to cashew nuts. IgE is produced by our immune system when it recognizes cashew nut proteins as harmful. This test helps to determine if you have an allergy to cashew nuts.
When you consume cashew nuts, your immune system may overreact and release IgE antibodies, triggering symptoms like itching, hives, swelling, difficulty breathing, or even a life-threatening allergic reaction called anaphylaxis. By measuring the IgE level, this test can confirm if your body has developed an allergic response to cashew nuts.
