Sample

Blood draw or sample collection at a local center

A cultivated rye grass-specific IgE blood test measures antibodies the immune system may produce against cultivated rye grass and its pollen. It is a screening tool for possible grass pollen sensitization and is not a diagnosis on its own. A healthcare provider may order it when someone has seasonal allergy symptoms that coincide with rye grass pollination, when reviewing a broader grass pollen panel, or when symptoms occur after time in fields where cultivated rye grass is grown. Results are read with symptom history.

• Cultivated rye grass-specific IgE Antibodies produced against cultivated rye grass and its pollen; used to assess sensitization to this grass.

• People with seasonal sneezing, congestion, or itchy eyes during grass pollen season
• Individuals who notice symptoms after time in fields or on lawns
• Those being evaluated for a suspected grass pollen allergy
• People with asthma or eczema that flares around grass pollen
• Anyone whose provider wants a cultivated rye grass marker on a grass panel

• No fasting is required for this IgE allergy test
• The blood sample can be collected at any time of day
• Tell the healthcare provider about any medications you take
• No special diet is needed before collection

The cultivated rye grass-specific IgE result is reported as a numeric level or class. A value above the reporting threshold may indicate sensitization to cultivated rye grass pollen, but sensitization does not always lead to symptoms. A low or undetectable level makes reactivity to this grass pollen less likely without fully ruling it out. Grass pollens often cross-react, so a provider may interpret cultivated rye grass alongside related grass markers. Discuss results with a healthcare provider before making changes.
