The brome grass allergy test is a blood test that checks whether your immune system reacts to brome grass, a common grass pollen that can trigger seasonal allergy symptoms. It is usually ordered when someone has ongoing sneezing, nasal congestion, itchy or watery eyes, or asthma-like symptoms during grass pollen season.
What it measures
- Brome grass specific IgE — The main marker; shows whether your blood contains antibodies that recognize brome grass pollen.
- Total IgE — Sometimes measured alongside specific IgE to give context, though it does not identify a specific allergy on its own.
- Other grass-specific IgE — May be tested together to see whether you react to related grasses such as timothy or Bermuda grass.
- Inhalant allergen panel — An optional group of common airborne allergens that can help show whether symptoms are seasonal or year-round.
Who it is for
A primary care clinician, allergist, or immunologist typically orders this test. It is most often used when symptoms follow a seasonal pattern or when skin testing is not practical.
Preparation
No fasting or special preparation is usually required. Tell your clinician about any medications you take, since some drugs can affect allergy testing.
Results and what they mean
Results are reported as a level or class for brome grass specific IgE, often alongside a reference range. A higher result suggests sensitization, but it does not by itself diagnose an allergy or predict how severe symptoms will be. A clinician interprets the result with your history and symptoms. This is general information, not medical advice.

Frequently asked questions
Do I need to stop my allergy medication before this test?
Antihistamines generally do not affect blood IgE tests the way they affect skin tests, but check with your clinician about your specific medications.
What does a positive result mean?
It means your blood contains antibodies that recognize brome grass. Your clinician will consider whether this matches your symptoms.
Can this test tell me how bad my allergies will be?
No. The level does not reliably predict symptom severity, so your clinician will interpret it with your history.
Is this test painful?
It uses a standard blood draw, so you may feel a brief pinch when the needle goes in.
