What Egg Components measures
Egg Components is most often requested in connection with allergy Testing, food Sensitivity and immunoglobulin E, which is why it sits within the allergy — specific IgE group at Wimpole Street.
Specific IgE tests measure the antibody your immune system has made against a particular allergen — a single food, pollen, animal, mould, insect venom, latex or drug. Component-resolved tests go a step further and measure IgE to individual proteins within an allergen source, which helps to separate a risk of severe reaction from cross-reactive sensitisation that causes only mild symptoms. Total IgE gives a general indication of allergic tendency but does not identify a trigger.
Who considers Egg Components
- People often consider specific IgE testing if they have had hives, lip swelling or wheeze soon after eating a particular food.
- Sneezing, itchy eyes and congestion in a predictable season or around a pet are common prompts for inhalant testing.
- Those who have reacted to a wasp or bee sting with more than local swelling may test venom IgE before considering immunotherapy.
- Component tests are often chosen by people with a peanut, tree nut or milk allergy who want a finer picture of risk.
- Anyone who cannot have skin-prick testing, perhaps because of eczema or antihistamine use, may opt for blood IgE instead.
Preparing for your Egg Components
- 1Antihistamines do not affect blood IgE results, so you can keep taking them.
- 2No fasting or special timing is needed.
- 3Bring a note of what you reacted to, how soon after exposure and what happened — it shapes which allergens are worth testing.
Sample for this test: venous blood sample (serum).
Understanding your Egg Components results
A raised specific IgE can indicate sensitisation to that allergen, and higher values are generally associated with a greater chance of clinical reaction, but sensitisation without symptoms is common. Component results can distinguish, for example, IgE to storage proteins in peanut (linked to systemic reactions) from IgE to pollen-related proteins (usually mild oral symptoms). Negative results make IgE-mediated allergy to that trigger less likely but do not address non-IgE or intolerance reactions.
Specific IgE shows sensitisation rather than allergy; a result is interpreted with your reaction history and, where needed, supervised challenge testing.
