Quick answer
The Region 4 Allergies panel is a regional IgE blood test covering 23 allergens common in the southern subtropical part of the country. It evaluates sensitization to tropical grasses, tree and weed pollens, mold spores, and indoor allergens typical of a warm, humid peninsula. The panel is used when persistent or seasonal symptoms suggest allergy but the triggers are unclear.
What this test measures
Subtropical environments can sustain allergen exposure for most of the year. Warm-season grasses such as Bahia and Bermuda release pollen over a long period, trees including oak and melaleuca pollinate in their own seasons, and weeds contribute throughout the warm months. High humidity supports mold growth, and air-conditioned homes may still harbor dust mite.
This panel measures allergen-specific IgE for 23 regionally relevant allergens from one blood sample. Reported targets may include tropical grass pollens, tree pollens, weed pollens, mold spores, dust mite, and animal dander. Each allergen is reported with a quantitative antibody level and a graded class.
People living in subtropical areas who notice symptoms that do not fit a short season may find this panel useful. It can also help when symptoms persist indoors or through the winter. A qualified healthcare provider interprets the results with the person's environment and symptom history.
