Watermelon (f329)

Watermelon can cause food allergy in sensitive individuals, presenting as oral allergy syndrome (itching, swelling of lips, tongue, throat), urticaria, dermatitis, angioedema, and shortness of breath. There is a risk of intestinal obstruction due to watermelon seeds. Cross-reactivity has been identified with pumpkin, melon, cucumber, zucchini, and others. Profilin (Cit la2) may cause cross-allergic reactions with other plant products. Sensitivity to profilin is associated with allergies to citrus fruits, melon, banana, tomato, and more.

• Diagnosis of allergic reactions to watermelon.
• Assessment of sensitization level and risk of allergy development.
• Monitoring the effectiveness of ongoing therapy.
• Evaluation of sensitization level after allergen avoidance.
• Assessment of immune system status.

FEIA (Fluorescence Enzyme Immunoassay), ImmunoCAP (Solid-phase Immunofluorescence) – quantitative determination of the allergen.

• 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 aged 1-5 years – 2-3 hours fasting.
