What this test is
This test measures specific IgE antibodies in the blood that are associated with allergic reactions to macadamia nuts. It is one tool a clinician may use, along with your history and other findings, to help evaluate a possible nut allergy.
What it measures
- Macadamia nut specific IgE — Reflects the level of IgE antibodies directed against macadamia nut proteins in the blood.
- Total IgE — Sometimes measured to provide context, though it is not specific to macadamia nut allergy.
- Other nut specific IgE — May be included in a panel to check for sensitivity to related or co‑reacting nuts.
What the test involves
A healthcare professional collects a small blood sample, usually from a vein in your arm, using a standard blood draw. The sample is then sent to a laboratory for analysis.
