A barley grass allergy test is a blood test that checks whether your immune system reacts to proteins found in barley grass, the young leafy part of the barley plant. It is usually ordered when someone has allergy symptoms after contact with barley grass, barley pollen, or products containing barley grass powder.
What it measures
- Barley grass specific IgE — Antibodies your immune system makes against barley grass proteins.
- Total IgE — A general measure of allergic antibody levels in your blood.
- Grass pollen specific IgE — Checks for reactions to related grass pollens that may cross-react.
- Cereal grain specific IgE — Checks for reactions to wheat, barley, rye, or oat proteins.
Who it is for
This test is typically ordered by a primary care clinician or an allergist. It may be requested when symptoms such as sneezing, itchy eyes, hives, or breathing changes appear after exposure to barley grass or barley grass supplements.
Preparation
No fasting is required. Tell your clinician about any antihistamines or other medicines you take, because some can affect allergy test results.
Results and what they mean
Results are reported as a level or class for each specific IgE marker, often from negative to strongly positive. A positive result means your immune system has antibodies to that substance, but it does not by itself diagnose an allergy. Only a clinician can interpret your results alongside your symptoms and history. This is general information, not medical advice.

Frequently asked questions
Do I need to stop taking allergy medicine before this test?
Ask your clinician. Some antihistamines can affect allergy testing, but do not stop any medicine without checking first.
Can this test tell me if I am allergic to barley food?
Not directly. It looks at barley grass and related proteins. A clinician may order food-specific tests if barley food allergy is suspected.
How long does it take to get results?
Most results are ready in 1 to 3 business days, though timing can vary by lab.
What does a positive result mean?
It means your blood has antibodies that react to barley grass proteins. Your clinician will decide whether that matches a true allergy based on your symptoms.
