Purpose of the Test

A wound swab for fungus stain/fungal smear (KOH) is a diagnostic test used to identify the presence of fungal infection in a wound. The test is ordered when a healthcare provider suspects a fungal infection in a wound.

When this test is required

The test may be requested when the healthcare provider suspects a fungal infection in a wound, particularly if there are signs of inflammation or if the wound is not healing properly. The test may also be ordered if the patient has a weakened immune system or if they have a history of fungal infections.

What the Test Detects

During the test, the swab is examined under a microscope after being treated with potassium hydroxide (KOH) solution. The KOH dissolves the skin cells, leaving the fungal elements visible, which can then be identified based on their shape and size.

Preparation for the Test

No specific test preparation is needed for the wound swab for fungus stain/fungal smear (KOH). However, it is important to inform the healthcare provider about any medications, supplements or herbal remedies you are taking, as some may interfere with the test results. It is also important to keep the wound clean and dry before the test to avoid contaminating the sample.

Sample Requirements

The sample required for the test is a swab of the wound. The healthcare provider will use a sterile swab to collect a sample from the infected area of the wound.

Additional Notes

It is important to note that the wound swab for fungus stain/fungal smear (KOH) is just one diagnostic tool and may be used in conjunction with other tests, such as a culture and sensitivity test, to confirm the presence of a fungal infection and determine the appropriate course of treatment.
