Order Walnut Allergy Test | Nut AllergiesA walnut allergy screen measures the amount of IgE antibodies in the blood that react to walnut proteins. Because IgE is the antibody class most closely associated with immediate allergic reactions, this test can help assess whether a person has become sensitized to walnut.
About Walnut Allergy Test | Nut Allergies in Orangevale
The walnut allergy screen is a blood test that looks for specific IgE antibodies directed against walnut.
During an allergic response, the immune system can produce IgE antibodies that recognize particular proteins in walnut. These antibodies bind to immune cells and, on re-exposure, can trigger symptoms such as hives, itching, swelling, or breathing difficulty. A blood sample is used to measure the level of walnut-specific IgE.
Results are reported as a quantitative value, often alongside a reference range that indicates how likely the finding is to be clinically significant. A detectable level suggests sensitization, but sensitization does not always mean that eating walnut will cause symptoms. The test result is therefore interpreted together with a person's history of reactions and other clinical information.
This screen is not a substitute for a medically supervised food challenge, which remains the definitive way to confirm a food allergy. It also does not predict the severity of a future reaction. A healthcare professional can explain what a given result means in an individual case and whether additional evaluation is needed.
