A garlic allergy test uses a blood sample to measure allergen-specific IgE antibodies against garlic proteins. Garlic belongs to the allium family, which also includes onion, leek, and chives, so reactions may 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 garlic or garlic-containing dishes, or as part of a broader food and spice evaluation. Results are interpreted with symptoms and medical history.

• Garlic-specific IgE Antibodies produced against garlic proteins; used to assess sensitization to garlic.

• People who develop hives, itching, or swelling after eating garlic
• Individuals with tingling or itching in the mouth after garlic-seasoned foods
• Those with digestive upset, nausea, or diarrhea after meals containing garlic
• People with eczema or skin reactions who suspect a garlic trigger
• Anyone who has reacted to related alliums such as onion, leek, or chives

• 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 garlic. An elevated value may indicate sensitization, but sensitization does not always mean a person will react when eating garlic. A low or undetectable level makes a true garlic allergy less likely, though it does not rule one out. Because garlic belongs to the allium family, a provider may consider cross-reactivity with onion, leek, or chives. Discuss all results with a healthcare provider before changing your diet.
