What Does This Test Measure?

IgE antibodies are a type of protein produced by your immune system in response to allergens, such as certain foods. When your body detects macadamia nuts as a threat, it may produce IgE antibodies specific to these nuts. This test measures the amount of these antibodies in your serum, which can help determine if you have an allergic reaction to macadamia nuts.

Your healthcare provider may recommend this test if you have symptoms like hives, swelling, difficulty breathing, or digestive issues after eating macadadia nuts. It can also be used to confirm allergies suspected through other methods, such as skin prick tests or food challenges.

How Is This Test Performed?

A small blood sample is taken from a vein in your arm. The blood is then sent to a laboratory where it is analyzed using an immunoassay method to detect IgE antibodies specific to macadamia nuts.

What Do the Results Mean?

Results are not provided with specific numeric ranges. High levels of IgE antibodies to macadamia nuts may suggest an allergic reaction to these nuts. Your healthcare provider will interpret the results in the context of your symptoms and medical history.
