American Elm details

American elm is one of the earliest-blooming trees in spring, and this test measures IgE antibodies specific to its pollen to check for allergic sensitization. A positive result can help explain seasonal allergy symptoms — sneezing, congestion, itchy or watery eyes — that show up especially early in the season, since elm often pollinates before many other trees. It's typically included as part of a regional tree allergen panel, since elm-sensitive individuals are often sensitive to other tree pollens too. As with other allergen tests, a positive result shows sensitization, and your doctor will weigh it against your actual symptom history and timing.
