Quick answer
The Region 19 Allergies panel is a regional IgE blood test covering 22 allergens common across a Caribbean island environment. It evaluates sensitization to tropical grasses, weeds, mold spores, dust mite, and other allergens that occur in warm, humid settings. The panel is used when year-round or seasonal symptoms suggest allergy but the specific triggers are not clear.
What this test measures
Tropical island environments can have year-round allergen exposure. Grasses such as Bermuda and Bahia release pollen across much of the year, weeds and trees add their own pollen seasons, and high humidity supports mold growth outdoors and indoors. Dust mite is often a significant indoor allergen in warm, humid homes.
This panel measures allergen-specific IgE for 22 regionally selected allergens from one blood sample. Targets may include tropical grass pollens, weed pollens, tree pollens, mold spores, dust mite, and animal dander. Each allergen is reported with a quantitative level and a graded class so the overall pattern can be reviewed.
People who live in or travel frequently to tropical island areas and notice persistent nasal, eye, or airway symptoms may order this panel. It can be especially helpful when symptoms do not follow a clear seasonal pattern. A qualified healthcare provider interprets the results with the person's environment and symptom history.
- Tropical grass pollen IgE (Bermuda, Bahia, and related grasses as included)
- Weed pollen IgE (common tropical weeds as included)
- Tree pollen IgE (common tropical trees as included)
- Mold spore IgE (Alternaria, Cladosporium, and related molds as included)
- Dust mite IgE when included
- Cat and dog dander IgE when included
- Allergen-specific IgE class for each of the 22 panel allergens
Why people order this test
- Investigate year-round allergy symptoms in a warm, humid climate
- Screen tropical grass and weed pollens in one blood draw
- Check whether mold spores contribute to persistent symptoms
- Assess dust mite sensitization common in humid indoor spaces
- Identify allergens to review with a qualified clinician
How to prepare
No fasting is needed, and the panel can be performed at any time of year. Follow the lab's routine instructions for the blood draw.
Understanding your results
Results typically return within one to three business days. Each allergen is reported separately, which helps separate year-round indoor triggers from overlapping outdoor pollen seasons. Positive results indicate sensitization, and a qualified healthcare provider interprets them with the person's history.

Frequently Asked Questions
Why do tropical panels emphasize dust mite?
Warm, humid indoor environments can support dust mite populations, making this allergen a common contributor to year-round symptoms.
Can mold allergy be significant on a tropical island?
Yes. High humidity can encourage mold growth in buildings and outdoors, so regional panels often include common mold allergens.
Are pollen seasons different in the tropics?
Many tropical grasses can pollinate for much of the year, so symptoms may not follow the distinct seasons seen in temperate climates.
Is this test done with a skin prick?
No. It is a blood test that measures IgE antibodies to the panel allergens.
What if symptoms continue after treatment changes?
Persistent symptoms deserve clinical review. The panel results can give the treating provider additional information to work with.
