ALLERGY TEST - FOOD VEG

You should get a veg food allergy test if you have hives, itching, lip or face swelling, eczema, abdominal pain, vomiting, diarrhea, or breathing difficulty after eating certain plant-based foods. It is also recommended for children with food-related eczema or poor growth, people with asthma or other allergies, and anyone with a past severe food reaction.

No special preparation or fasting is required for a veg food allergy test. Since it is a blood test, antihistamines do not affect the results, so you can usually continue them. Do not eat suspected trigger foods just for testing. Inform your doctor about steroids, immunosuppressants, or omalizumab, and note which foods caused symptoms.

No, fasting is not required for a veg food allergy test. You can eat and drink normally before giving your blood sample, though you should avoid foods you already suspect cause reactions. Antihistamines don’t affect the results of this blood test, so you can usually continue them.
