The Trichophyton rubrum allergy test is a blood test that checks for an allergic response to Trichophyton rubrum, a common fungus that causes skin, nail, and scalp infections. It is ordered when a person has persistent or unusual allergy symptoms and a fungal infection is suspected as the trigger.

What it measures

Trichophyton rubrum-specific IgE — Antibodies that suggest an allergic reaction to this fungus.
Total IgE — A general measure of allergic tendency, sometimes included for context.
Eosinophil count — A type of white blood cell that can rise with allergies.

Who it is for

Allergists, dermatologists, or primary care clinicians may order this test when evaluating chronic hives, eczema, or respiratory symptoms that could be linked to a fungal allergy.

Preparation

No fasting or special preparation is needed. Tell your clinician about any medications you take, as some may affect test results.
