Immunologic Tests:
Immune testing is useful for screening patients as a diagnostic tool.
RadioAllergenSorbent Test (RAST) (in which the serum is mixed with food on a paper tablet and then washed with radioactive material and an IgE marker) and the Enzyme-Linked Immunosorbent Assay (ELISA) is similar to RAST but does not use radioactive material ) Are diagnostic methods that have been replaced by the CAP-FEIA blood test.
Fluorescein-Enzyme Immunoassay (CAP-FEIA)
Is a blood test that appears promising in the diagnosis of food allergies because it provides a quantitative assessment of the specific IgE antibodies and higher levels of antibodies that predict clinical symptoms.
This blood test is 96% -100% accurate in determining the sensitivity of children to milk, eggs, fish and peanuts. However, the sensitivity of soy is still 86%. The effectiveness of this test has been demonstrated by testing for food-sensitized children whose food sensitivity has been confirmed by food tests Double Blind Controlled Food Challenges (DBPCFCs).
