Perennial rye grass pollen, a late spring to summer grass pollen, is the allergen this blood test checks your IgE against. It is a pollen test, not a test for rye as a food. Sensitization is not the same as allergy, so the result is read with your history. No fasting is needed.
For adults 18 and older. Test availability varies by lab location.

What does this test measure?
Your result shows whether your blood has IgE to perennial rye grass pollen. Read with the timing of your symptoms, it can help a healthcare provider see whether this pollen may play a part.
- Perennial rye grass pollen-specific IgE (g5)
- Specific IgE is an antibody the immune system can make against one allergen. This marker measures IgE that recognizes perennial rye grass pollen, a late spring to summer grass pollen. A level above the lab’s reference range shows sensitization, read with the timing of your symptoms.
- Why it’s measured: Checks for IgE sensitization to perennial rye grass pollen when symptoms follow the late spring to summer season.

Not on its own. A positive result means your immune system has made IgE to perennial rye grass pollen, which is called sensitization. Many people who are sensitized have no symptoms when they are exposed.
A diagnosis of allergy is made by a healthcare provider who looks at your symptoms and history along with results like this one. A negative result also does not by itself mean you are not allergic.
No. This test measures IgE to perennial rye grass pollen, which is usually checked for seasonal symptoms. Rye as a food has its own test, so this result does not tell you whether you will react to eating rye.
Decisions about eating any food belong with an allergist, who reads pollen and food results together with your history.
Perennial rye grass pollen is a late spring to summer grass pollen, common in lawns and pastures. Pollen seasons can shift with weather and location.
When your symptoms happen is one clue an allergist uses alongside a result like this. A positive result shows sensitization, not that this pollen causes your symptoms.
It can. Grass pollens share similar proteins, so sensitization to one grass can come with sensitization to others. That is one reason an allergist may look at several grass results together.
Cross-reaction in a blood test does not show which grass is behind your symptoms, or whether you will have symptoms at all.
Yes. Perennial rye grass pollen is one of the allergens in the Southwest allergy evaluation. Each panel measures IgE to a set of allergens the lab groups together, in one draw.
Panel results are read like single tests. Sensitization is not the same as allergy.
