Trichophyton Mentagrophytes Antibody Test in Arizona

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.
