Caster bean seeds and pollens can act as allergens and are known to develop sensitivity. Castor bean allergen-1 (CB1A) is the main allergen of the castor bean. Clinically, these allergens can induce mild rhinitis, conjunctivitis, gastrointestinal symptoms, atopy, or occasionally anaphylaxis. Healthcare professionals use this test to assess allergy status and guide allergen-specific immunotherapy.

Important note: Minimum volume is 1 mL and 0.5 mL for every additional allergen.
