The alfalfa allergy test is a blood test that looks for antibodies your immune system may make against alfalfa, a flowering plant used in hay, sprouts, and some herbal products. It is usually ordered when a person has symptoms such as hives, nasal congestion, or wheezing after contact with or exposure to alfalfa.

What it measures

  • Alfalfa-specific IgE — The main marker; IgE is an antibody linked to allergic reactions.
  • Total IgE — Sometimes measured to give context, though it cannot confirm a specific allergy.
  • Other pollen-specific IgE — May be checked because alfalfa can cross-react with some grasses and pollens.
  • Serum tryptase — Occasionally added if a severe reaction is being evaluated.

Who it is for

A primary care clinician or allergist typically orders this test when a person reports symptoms that may be related to alfalfa exposure.

Preparation

No fasting is required. Tell your clinician about all medicines, especially antihistamines, because some can affect allergy testing.

Results and what they mean

Results are reported as a level of alfalfa-specific IgE, often shown as a number or class. A clinician interprets the result alongside your symptoms and history, since a positive test alone does not always mean you have an allergy. This is general information, not medical advice; discuss your results with a qualified healthcare professional.

Not necessarily. It means your blood contains antibodies that recognize alfalfa. A clinician decides whether that reflects a true allergy based on your symptoms.

Do I need to stop eating alfalfa sprouts before the test?

Ask your clinician. In most cases, no special diet change is needed, but follow any instructions you are given.

How long do results take?

Results are usually available within 1 to 3 business days, though timing can vary by lab.

Can this test find out if I am allergic to other plants?

No. This test focuses on alfalfa. Your clinician may order additional tests if other allergies are suspected.
