Why This Biomarker Matters

A positive result identifies white alder as a seasonal allergen trigger; higher antibody levels may correlate with more severe allergic symptoms.

Understanding Your Results

Normal Range

12 ug/dL

Overview

This test detects and quantifies IgE antibodies against white alder pollen, a tree allergen common in specific geographic regions. People allergic to white alder pollen experience seasonal allergic rhinitis symptoms—sneezing, nasal congestion, and itchy or watery eyes—typically during the tree's pollination season. The quantitative nature of this test (measuring the amount of antibodies, not just presence) helps assess the severity of your allergic response.
