Helminthosporium Halodes Allergy Panel in Arizona

What this test measures

Helminthosporium halodes is a mold species that grows on plant material, including cereal grains, grasses, and fabrics stored in damp conditions. Its spores become airborne and can trigger allergic rhinitis, coughing, or skin symptoms in sensitive people. The test measures specific IgE antibodies produced against the mold.

Only a serum sample from a routine blood draw is needed, and testing can be performed at any time of year. Laboratories report Helminthosporium halodes-specific IgE, total IgE, and a reactivity class. Mold panels often include related species such as Alternaria, Cladosporium, and Aspergillus so a clinician can see the broader sensitization pattern.

People order this test when symptoms persist indoors, in damp buildings, or around stored grain and textiles, or when a mold allergy panel is being assembled. Because mold exposure is widespread, the result is interpreted alongside the home, work, and seasonal exposure history.
