A lemon allergy test uses a blood sample to measure allergen-specific IgE antibodies against lemon proteins, typically as part of a citrus panel. People who react to one citrus fruit may also react to others, so a panel covering several citruses gives a broader picture than a single marker. The test is a screening tool for suspected food allergy, not a diagnosis on its own. A provider may order it after a reaction to lemon or other citrus, or as part of a wider fruit allergy workup. Results are interpreted with symptoms and history.

• Lemon-specific IgE Antibodies produced against lemon proteins; used to assess sensitization to lemon.
• Lime-specific IgE Antibodies produced against lime proteins; used to assess sensitization to lime.
• Orange-specific IgE Antibodies produced against orange proteins; used to assess sensitization to orange.
• Grapefruit-specific IgE Antibodies produced against grapefruit proteins; used to assess sensitization to grapefruit.
• Tangerine-specific IgE Antibodies produced against tangerine proteins; used to assess sensitization to tangerine.

• People who develop hives, itching, or swelling after eating lemon or other citrus
• Individuals with tingling or itching in the mouth after citrus fruits or juices
• Those with digestive upset, nausea, or diarrhea after citrus
• People with eczema or skin reactions who suspect a citrus trigger
• Anyone who has reacted to one citrus and needs the others checked

• No fasting is required for this IgE allergy panel
• 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

Each citrus is reported with its own IgE value or class. An elevated lemon, lime, orange, grapefruit, or tangerine result may indicate sensitization, but sensitization does not always mean a person will react when eating that fruit. A low or undetectable level makes a true allergy to that citrus less likely. Because citrus fruits share some proteins, a positive result for one may accompany reactions to others. Discuss all results with a healthcare provider before changing your diet.
