The main allergenic components of orange include Cit s1, Cit s2, Cit s3, Cit s IFR, which can cause cross-allergic reactions with other products.
FEIA (Fluorescence Enzyme Immunoassay), ImmunoCAP (Solid-phase Immunofluorescence) – quantitative determination of sensitization level to orange allergen.
- Diagnosis of allergic reactions to orange.
- Assessment of sensitization level and risk of allergy development.
- Monitoring therapy effectiveness.
- Assessment of sensitization level after allergen avoidance.
- Evaluation of immune system status.
- Blood should be drawn in the morning on an empty stomach or 4 hours after eating.
- Drinking plain still water is allowed.
- Do not smoke for 30 minutes before the test.
- For children under 1 year – no food 30-40 minutes before the test; for children 1-5 years – 2-3 hours fasting.
The test helps detect orange allergy, which is important due to the widespread use of this fruit in food and cosmetics. Knowing the sensitization level helps avoid potentially dangerous reactions and monitor treatment effectiveness. Detection of cross-reactions aids in comprehensive diagnosis of food allergies.
