The Trichophyton mentagrophytes allergy test is a blood test that checks for allergic sensitization to a common mold-like fungus found in soil, damp indoor spaces, and on skin. It is ordered when a clinician suspects that allergy to this fungus may be contributing to asthma, allergic rhinitis, or eczema symptoms.
What it measures
- Specific IgE to Trichophyton mentagrophytes — The main marker; it shows whether your immune system has made allergic antibodies against this fungus.
- Total IgE — Sometimes measured alongside to give a general sense of your overall allergic antibody level.
- Other mold-specific IgEs — May be included to check for reactions to other common molds such as Aspergillus or Alternaria.
Who it is for
This test is usually ordered by an allergist, immunologist, or primary care clinician for people with ongoing asthma, nasal allergies, or eczema that may be linked to mold exposure.
Preparation
No fasting or special preparation is required. You can eat, drink, and take your usual medications unless your clinician tells you otherwise.
Results and what they mean
Results are reported as a number that indicates whether specific IgE to Trichophyton mentagrophytes was detected and how high it is. A clinician interprets this value together with your symptoms, history, and other tests; it does not by itself diagnose an allergy or disease. This is general information, not medical advice.

Frequently asked questions
Does a positive result mean I am allergic to this fungus?
Not necessarily. A positive result shows sensitization, meaning your immune system has reacted to the fungus in a blood test. Whether that causes symptoms depends on your overall health picture, so a clinician must interpret it.
Is this test painful?
It is a standard blood draw, so you may feel a brief pinch when the needle goes in. Most people tolerate it well.
How long does it take to get results?
Results are typically available within 1 to 3 business days, though this can vary by laboratory.
Do I need to avoid any foods before the test?
No. There are no fasting or food restrictions for this test.
