An alfalfa IgE allergy test measures antibodies against alfalfa proteins. Alfalfa is a flowering legume used as a forage crop and sometimes eaten as sprouts or taken in supplements, and its pollen and plant proteins can trigger allergic reactions in sensitized people. The test is a screening tool rather than a diagnosis on its own. It may be ordered after a suspected reaction to alfalfa or as part of a broader allergy evaluation.

• Alfalfa-specific IgE Antibodies produced against alfalfa proteins; an elevated level can suggest sensitization to alfalfa.

• Symptoms such as hives, itching, or nasal irritation after contact with alfalfa or its pollen
• Oral itching or swelling after eating alfalfa sprouts
• Seasonal allergy symptoms near alfalfa fields or pollen sources
• Occupational exposure to alfalfa through farming or animal feed
• A clinician is evaluating a suspected plant or pollen allergy

• No fasting is required for this IgE antibody test.
• Tell the collector about allergy medications you take, as some can affect allergy testing.
• If you have had a severe reaction to alfalfa, mention it so the collection can be planned safely.

Results are reported as alfalfa-specific IgE. A low or undetectable level suggests no meaningful sensitization, while an elevated level may indicate the immune system recognizes alfalfa proteins and can be associated with allergic symptoms. This test alone cannot distinguish pollen from food sensitization, and a positive result does not confirm that alfalfa caused a reaction. Discuss your results with a healthcare provider for proper interpretation.
