Rapeseed (f316)1590
Rapeseed (canola) – a plant of the Brassicaceae family, an important source of edible oil. The main allergenic component of rapeseed is Bra n1, a 2S albumin (napin), resistant to digestion and denaturation. Although oil refining usually removes allergens, cold-pressed oil may retain proteins that cause allergic reactions. Occupational exposure to rapeseed can cause inhalation allergies with respiratory symptoms.
Rapeseed is the third largest source of vegetable oil worldwide. The main allergenic component Bra n1 makes up about 20% of the seed protein and is resistant to digestion. Cross-reactivity with mustard allergens is possible, but clinical cases are limited. The test helps detect sensitization and prevent allergic reactions, especially in occupational risk groups.
- Diagnosis of allergic reactions to rapeseed.
- Assessment of sensitization level and risk of allergy development.
- Monitoring therapy effectiveness.
- Evaluation of sensitization level after allergen avoidance.
- Assessment of immune system status.
FEIA (Fluorescence Enzyme Immunoassay, ImmunoCAP) – quantitative determination of the allergen.
Please note that the research method and reference values may vary depending on the equipment and test systems used.
- 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.
