What this test is
This is a blood test that measures specific IgE antibodies directed against pistachio. IgE antibodies are part of the immune response that can trigger allergy symptoms. The test is used alongside your history and other findings to evaluate possible pistachio allergy.
What it measures
- Pistachio-specific IgE — Reflects the amount of IgE antibody directed against pistachio proteins in the blood.
- Total IgE (if included) — Sometimes measured to provide context, though it is not specific to pistachio.
- Other tree nut-specific IgE (if a panel is ordered) — May be included to check for cross-reactivity or multiple nut sensitivities.
What the test involves
A healthcare professional collects a small sample of blood, usually from a vein in your arm. The sample is then sent to a laboratory for analysis.
Why it is often ordered
A clinician may order this test if you have had symptoms after eating pistachios or other tree nuts. It can also be used to help evaluate a suspected nut allergy when the history is unclear.
Preparation
No special preparation is typically required, but follow the instructions provided by the collection lab. Tell the lab about any medications you take, as some may affect test interpretation.
How results are reported
Results are reported as a numeric level of specific IgE, often with a qualitative interpretation such as negative, low, moderate, or high. Reference ranges and reporting formats vary by laboratory, so your results should be interpreted in the context of your clinical history.
