Cashew Allergy Test
A cashew allergy blood test measures IgE antibodies against cashew proteins. Cashew is a tree nut that can cause reactions ranging from mild oral symptoms to severe anaphylaxis, and it is closely related to pistachio.

Quick answer
The cashew allergy test measures immunoglobulin E antibodies against cashew proteins in a blood sample. Cashew is a tree nut and a common cause of food allergy, with reactions that can range from itching and hives to breathing difficulty. Cashew is closely related to pistachio, so sensitivity to one may accompany sensitivity to the other. A qualified healthcare provider interprets the result.
What this test measures
Cashew is the seed of a tropical tree and belongs to the same plant family as pistachio and mango. Tree nut allergies are among the more persistent food allergies, and reactions can be serious. Even small amounts can trigger symptoms in highly sensitive people, so identifying the specific nut is useful for planning and avoidance.
The test measures allergen-specific IgE against cashew in serum using a laboratory immunoassay. It reports whether antibodies are present and may include a quantitative level or reactivity class. Because cashew and pistachio share allergens, results are often reviewed together with other tree nut tests to map the pattern of sensitization.
A positive result indicates that the immune system recognizes cashew proteins, but it does not predict how severe a future reaction will be. A healthcare provider uses the result with the reaction history and may recommend additional evaluation. Anyone who has had a severe reaction should seek medical guidance promptly.
- Cashew specific IgE
- Total serum IgE
- Quantitative allergen-specific IgE level
- IgE reactivity class for cashew
- Cross-reactive pistachio allergens
- Other tree nut specific IgE within the panel
Why people order this test
- Investigate reactions after eating cashew or products containing it
- Clarify sensitization when a nut panel is positive
- Assess cross-reactivity with pistachio
- Support dietary planning with a qualified provider
- Follow up after a suspected food reaction
How to prepare
No fasting is required. A blood sample is drawn from a vein, usually at the arm. Follow the laboratory's instructions, especially if the test is part of a broader nut allergy panel.
Understanding your results
Results are usually available within one to three business days. The report shows the specific IgE level and reactivity class for cashew. An elevated value indicates sensitization, and a healthcare provider interprets it with the person's reaction history and other findings.

Frequently Asked Questions
What is a cashew allergy?
It is an immune reaction to proteins in cashew, a tree nut. Symptoms can range from oral itching and hives to breathing difficulty.
Is cashew related to other nuts?
Cashew is closely related to pistachio and shares allergens with it, so sensitivity to one often accompanies sensitivity to the other.
How is the test performed?
A small blood sample is drawn and analyzed for IgE antibodies that react to cashew proteins.
Does a positive test mean I will have a severe reaction?
Not necessarily. The result shows sensitization and does not predict the severity of a future reaction.
Do I need to fast?
No fasting is required for this blood test.
