Allergen, Food, Lemon

Also known as: LEMON

Clinical Use

Use

This test measures the IgE antibody specific to lemon, helping to determine the potential for allergic reactions. Lemon allergies, like other food allergies, can elicit a variety of symptoms, ranging from mild to severe. The quantification of specific IgE antibodies can support clinicians in evaluating the likelihood of allergic reactions in patients with suspected lemon allergies and can be a useful component in comprehensive allergy assessments.

Special Instructions

Not provided.

Limitations

Test results of 0.10-0.34 kU/L should be interpreted with caution as clinical relevance is undetermined, requiring specialist consultation. Higher IgE levels indicate increasing concentrations of allergen-specific antibodies but may not correlate directly with the severity of clinical symptoms or skin test results. Thus, results should be correlated with the patient's clinical history and reactivity to specific allergens. A negative result does not fully exclude the possibility of clinical allergy or anaphylaxis.
