Allergen, Food, Tomato
Also known as: TOMATO
Use
This test measures allergen-specific IgE levels for tomato allergens using Quantitative ImmunoCAP Fluorescent Enzyme Immunoassay. It helps assess the probability of IgE-mediated clinical reactions to tomatoes, assisting in allergy diagnosis and management. IgE levels are reported in kU/L, with the classification provided to interpret the probability of clinical reactions.
Special Instructions
Not provided.
Limitations
Even though increasing IgE levels are reflective of higher allergen-specific IgE concentrations, they may not correspond with the degree of clinical response or skin test results when exposed to specific allergens. Negative test results do not rule out the possibility of a clinical allergy or anaphylaxis. It is essential to correlate laboratory results with the clinical history and in vivo reactivity. Results of 0.10-0.34 kU/L should be interpreted by a specialist as their clinical significance is undetermined.
