# Fungal Antibodies, Quantitative Double Immunodiffusion

> This test measures the amount of antibodies, which are proteins your immune system creates to fight fungal infections. It helps show whether persistent symptoms, such as lung issues or fever, are likely caused by a fungus rather than bacteria or viruses. This distinction helps rule out other types of infections that require different treatments. However, this test alone cannot confirm an active infection or identify the exact fungal species without additional clinical data.
