No special preparation is required for this test. However, it is important to inform your healthcare provider of any medications you are taking, including antibiotics, antifungal agents, and immunosuppressive drugs, as these may affect the test results. In summary, if you have a persistent or recurrent wound infection, your healthcare provider may recommend a wound secretion for fungus C/S with a fungus stain (KOH) test to identify the type of fungi causing the infection and determine the appropriate treatment.
