# Walnut

> This test measures the amount of specific antibodies in your blood that react to proteins found in walnuts. It helps identify if your immune system is sensitive to this tree nut, which is useful for investigating symptoms like hives, swelling, or stomach pain after eating. This result helps distinguish a specific reaction to walnuts from other food sensitivities or digestive issues. However, this test cannot predict exactly how severe an allergic reaction will be or confirm a diagnosis without a full clinical evaluation.
