Sample

Blood draw or sample collection at a local center

A green bell pepper allergy test uses a blood sample to measure allergen-specific IgE antibodies against proteins in green bell peppers. Bell peppers are nightshades, a family that also includes tomato, potato, and eggplant, so reactions can sometimes overlap with sensitivity to those foods. The test is a screening tool for suspected food allergy rather than a diagnosis on its own. A provider may order it after a reaction to bell peppers or related produce, or as part of a broader vegetable allergy evaluation. Results are read with symptoms and history.

• Green bell pepper-specific IgE Antibodies produced against green bell pepper proteins; used to assess sensitization to green bell peppers.

• People who develop hives, itching, or swelling after eating green bell peppers
• Individuals with tingling or itching in the mouth after peppers
• Those with digestive upset, nausea, or diarrhea after bell peppers
• People with eczema or skin reactions who suspect a nightshade trigger
• Anyone who has reacted to related foods such as tomato, potato, or eggplant

• No fasting is required for this IgE allergy test
• The blood sample can be collected at any time of day
• Tell the provider about all medications you take
• No special diet is needed beforehand

Results are reported as an IgE level or class for green bell pepper. An elevated value may indicate sensitization, but sensitization does not always mean a person will react when eating peppers. A low or undetectable level makes a true green bell pepper allergy less likely, though it does not rule one out. Because peppers are nightshades, a provider may consider cross-reactivity with tomato, potato, or eggplant. Discuss all results with a healthcare provider before changing your diet.
