Sample

Blood draw or sample collection at a local center

A grey alder pollen-specific IgE blood test measures antibodies the immune system may produce against pollen from the grey alder tree. It is a screening tool for seasonal tree pollen allergy, not a diagnosis on its own. Clinicians may order it when sneezing, itchy eyes, or respiratory symptoms cluster during the tree pollen season, or when reviewing a regional tree pollen panel. Results are interpreted with symptom timing and exposure history.

• Grey alder tree pollen-specific IgE IgE antibodies directed against grey alder pollen proteins; used to assess sensitization to this tree pollen allergen.

• Seasonal sneezing, runny nose, or itchy, watery eyes during tree pollen season
• Symptoms that worsen near alder trees or on windy days
• Known pollen sensitivity when component-level testing is desired
• Evaluation as part of a tree pollen or regional allergy panel

• No fasting is required for most IgE allergy tests
• Report antihistamines and other medications, as some may affect interpretation
• A single blood draw is collected; no special diet or timing is needed

The grey alder tree pollen-specific IgE result is reported as a level, often described as negative, low, moderate, or high. A detectable or elevated level may indicate sensitization to grey alder pollen, but it does not confirm that this pollen is causing symptoms. A negative result does not completely rule out allergy. Alder pollen can cross-react with birch and related tree pollens, so discuss results with a healthcare provider.
