Helminthosporium Halodes in North Carolina

This blood test checks for allergic sensitization to Helminthosporium halodes, a mold that grows on plants and in soil. It is usually ordered when a person has ongoing allergy or asthma symptoms and a clinician wants to see whether this mold may be a trigger.

What it measures

Specific IgE antibody to Helminthosporium halodes — The main marker; it shows whether your immune system has made antibodies that react to this mold.
Total IgE — Sometimes measured alongside to give context, though it does not identify a specific trigger.
Other mold-specific IgE tests — May be ordered together to compare reactions to several molds.
Allergen panel components — If part of a broader panel, results for related allergens may be reported together.

Who it is for

A primary care clinician, allergist, or pulmonologist typically orders this test. It is most often used for people with persistent nasal, eye, or breathing symptoms that may worsen in damp or moldy environments.

Preparation

No fasting or special preparation is needed. Tell your clinician about any antihistamines or other medicines you take, because some can affect allergy testing.

Results and what they mean

Results are usually reported as a number or class level for specific IgE, along with a reference range from the lab. A higher result suggests sensitization but does not by itself confirm that this mold causes your symptoms. Only a clinician can interpret the result with your history and exam; this is general information, not medical advice.
