Blood draw or sample collection at a local center

A timothy grass-specific IgE blood test measures antibodies the immune system may produce against timothy grass and its pollen, sometimes referred to as hay. It is a screening tool for possible grass pollen sensitization rather than a diagnosis on its own. A healthcare provider may order it when someone reports seasonal allergy symptoms that overlap with timothy pollination, when reviewing a broader grass pollen panel, or when symptoms occur after time in fields and meadows where this grass is common. Results are interpreted with symptom history.

• Timothy grass-specific IgE Antibodies produced against timothy 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 meadows
• Those being evaluated for a suspected grass pollen allergy
• People with asthma or eczema that flares around grass pollen
• Anyone whose provider wants a timothy 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 timothy grass-specific IgE result is reported as a numeric level or class. A value above the reporting threshold may indicate sensitization to timothy grass pollen, but sensitization does not always produce symptoms. A low or undetectable level makes reactivity to this grass pollen less likely without fully ruling it out. Timothy grass is a common marker used to represent grass pollen sensitization, and a provider may interpret it alongside related grasses. Discuss results with a healthcare provider before making changes.
