Allergen, Food, Pistachio
Also known as: PISTACHIO
Use
This test measures the concentration of allergen-specific IgE antibodies in the patient's serum, specifically targeting pistachio. It helps identify if a patient is sensitized to pistachio by providing the probability of an IgE-mediated allergic reaction. The results are given in concentration ranges that correlate with different classes of allergen-specific IgE response, from no significant detection to very high levels, which assist clinicians in interpreting potential allergic response severity.
Special Instructions
Not provided.
Limitations
Allergen-specific IgE concentration does not always correlate with clinical reactivity, so results should be interpreted in context with the patient's clinical history and possible in vivo testing. A negative test does not rule out the possibility of an allergy or even anaphylaxis. Results in the range of 0.10-0.34 kU/L should be used by specialists as their clinical relevance is undetermined.
