Test Name: Cashew Nut Component IgE Test

Synonyms: Cashew-specific IgE Component Test, Cashew Allergen Profile

Purpose of Test

This test measures the presence and concentration of IgE antibodies specific to certain protein components in cashews. It offers a more detailed and specific evaluation of a patient's sensitivity to cashews than a general IgE test for whole food allergens.

Clinical Significance

Specificity: Whole food allergen IgE tests, although sensitive, can sometimes yield positive results in patients who do not have a true food allergy. This can be due to cross-reactivity with other substances or non-specific binding.
Better Predictive Value: By examining specific protein components of the cashew nut, the Cashew Nut Component IgE Test can more accurately predict the likelihood of a true allergy. Some components may be more associated with severe allergic reactions, while others might correlate with milder symptoms or even be related to cross-reactivity with other foods or pollens.
Comprehensive Diagnosis: A definitive diagnosis of a cashew nut allergy should never rely solely on the results of the Cashew Nut Component IgE Test. A comprehensive evaluation that includes this test, combined with a thorough physical examination and a detailed clinical history, will provide the most accurate diagnosis.

Interpreting the Results

  • Negative Result: No significant levels of cashew-specific IgE detected. This suggests a low likelihood of a cashew allergy but does not rule it out entirely.
  • Positive Result: Elevated levels of cashew-specific IgE detected. The specific protein components to which the IgE antibodies bind can provide further insight into the potential severity of the allergy, cross-reactivity, and clinical relevance.


Some medications or conditions might interfere with the test results.


The Cashew Nut Component IgE Test provides deeper insight into a patient's potential allergy to cashews. By targeting specific protein components, it offers a higher level of specificity than whole food allergen tests. However, as with any diagnostic test, results should be interpreted in conjunction with a full clinical evaluation.
