About this test
A Brussels sprouts-specific IgE blood test checks for antibodies the immune system produces against Brussels sprout proteins. It is a screening tool for suspected food allergy and is not a diagnosis on its own. A healthcare provider may order it after a reaction to Brussels sprouts or related vegetables, or as part of a wider vegetable panel. Because Brussels sprouts belong to the same plant family as cabbage, broccoli, and cauliflower, results may be considered alongside those related markers.
What this test measures
- Brussels sprouts-specific IgE Antibodies produced in response to Brussels sprout proteins; used to assess sensitization.
Who this test may be right for
- People who develop hives, itching, or swelling after eating Brussels sprouts
- Individuals with mouth tingling or irritation after cruciferous vegetables
- Those with digestive upset, vomiting, or diarrhea after Brussels sprouts
- People with eczema or skin reactions who suspect a vegetable trigger
- Anyone with a history of reaction to Brussels sprouts or related vegetables
Before your visit
- No fasting is required for this IgE allergy test
- The blood sample can be collected at any time
- Tell the provider about medications you take
- No special diet is needed beforehand
Understanding your results
The Brussels sprouts-specific IgE result is reported as a numeric level or class. A value above the reporting threshold may indicate sensitization to Brussels sprout proteins, but sensitization does not always cause symptoms. A low or undetectable level makes a true allergy less likely without completely ruling it out. Brussels sprouts share proteins with cabbage, broccoli, and cauliflower, so a provider may consider cross-reactivity among those markers. Discuss results with a healthcare provider before changing your diet.
