Why This Test Is Done
Your healthcare provider may recommend this test if you have symptoms such as persistent itching, redness, scaling, or unusual growths on your skin, especially in areas like the trunk, groin, or between toes. It can also be used to confirm a suspected fungal skin infection before starting treatment.
What to Expect During the Test
A healthcare professional will collect a sample from your skin using a swab or probe. The sample is then analyzed in a lab to detect fungal antigens, which are specific proteins produced by certain fungi. The result is qualitative, meaning it only indicates whether the fungus is present or not.
Sample Collection and Preparation
No special preparation is needed before this test. You may shower or wash the area if it is dirty or irritated, but avoid using lotions, creams, or ointments on the skin where the sample will be taken. Follow your provider’s instructions carefully.
Test Results and Interpretation
Results are typically reported as either positive (fungal antigen detected) or negative (no fungal antigen detected). A positive result suggests the presence of a fungal infection, while a negative result means no fungal antigens were found in the sample.
