Quick answer
The Trichophyton mentagrophytes allergy test measures immunoglobulin E antibodies against a dermatophyte, a type of fungus that infects skin, hair, and nails. It is used when a provider wants to know whether the immune system is sensitized to this organism, often alongside other mold or fungal allergy tests. A blood sample is required, and the result is interpreted with the person's symptoms and exposure history.
What this test measures
Trichophyton mentagrophytes is a dermatophyte, meaning it feeds on keratin in skin, hair, and nails. It is a common cause of conditions such as athlete's foot and ringworm. Beyond direct infection, exposure to its proteins can prompt an allergic response in some people, contributing to itching, rashes, or worsening of existing skin conditions.
The test measures specific IgE antibodies in serum using a laboratory immunoassay and reports a level along with a reactivity class. Because dermatophyte and mold allergens can overlap, results are typically reviewed with other fungal markers. A single blood draw is enough, and no fasting is usually needed.
A positive result indicates that the immune system recognizes the organism, which is not the same as an active infection. Allergic sensitization and infection are separate findings. A qualified healthcare provider considers the result with the skin examination, history, and any other testing before deciding on next steps.

Frequently Asked Questions
What is Trichophyton mentagrophytes?
It is a dermatophyte fungus that can infect skin, hair, and nails, and is a common cause of athlete's foot and ringworm.
Does a positive allergy test mean I have a fungal infection?
No. The test shows immune sensitization, which is separate from an active infection. A provider evaluates both possibilities.
How is the sample collected?
A small blood sample is drawn from a vein and analyzed for IgE antibodies that react to the fungus.
Do I need to fast?
Fasting is not required unless the test is combined with another panel that calls for it.
Why test for mold allergy if I have a skin condition?
Allergic responses to fungi can contribute to skin symptoms, so testing helps a provider understand the full picture.
