The broccoli allergy test is a blood test that looks for specific antibodies your immune system may make against broccoli proteins. It is usually ordered when a person has had allergic symptoms after eating broccoli or other foods in the same plant family.
What it measures
- Broccoli-specific IgE — The main marker; IgE is an antibody linked to allergic reactions.
- Total IgE — A general measure of allergic antibody levels, which can help with context.
- Other food-specific IgE — Sometimes tested alongside to check for related allergies, such as to other vegetables.
Who it is for
This test is typically ordered by an allergist or primary care clinician for people who have had hives, swelling, trouble breathing, or digestive symptoms after eating broccoli.
Preparation
No fasting or special preparation is needed for this blood test. You can eat and drink normally before your appointment unless your clinician gives other instructions.
Results and what they mean
Results are reported as a level of broccoli-specific IgE, often with a reference range. A clinician interprets the number along with your symptoms and history; a high level alone does not always mean you are allergic. This is general information, not medical advice.

Frequently asked questions
Does a positive result mean I am definitely allergic to broccoli?
Not always. A positive result shows your immune system has made antibodies to broccoli, but only a clinician can tell if that means a true allergy based on your symptoms.
Can I eat broccoli before the test?
Yes. This test does not require fasting, so eating broccoli beforehand will not affect the result.
How long does it take to get results?
Most results are ready within 1 to 3 business days.
Is this test painful?
It is a standard blood draw from a vein, which feels like a quick pinch. There is no need to avoid any foods afterward.
