Purpose of the Test

A fungal stain test like KOH preparation on wound secretions is used to detect the presence of fungal organisms in a sample. It is commonly used to diagnose fungal infections in wounds, such as infected wounds or chronic non-healing wounds.

When this test is required

A healthcare provider may request a wound secretion fungal stain test like KOH preparation if a person has a wound that is not healing, has increased pain or redness, or shows signs of inflammation or discharge. The test may be ordered if other diagnostic tests, such as a bacterial culture, are inconclusive or if there is a suspicion of a fungal infection.

What the Test Detects

A wound secretion sample is tested for the presence of fungal organisms using a fungal stain test like KOH preparation. This test is used to diagnose fungal infections in wounds.

Preparation for the Test

Test preparation for a fungal stain test like KOH preparation on wound secretions is relatively simple. The sample is collected using a sterile technique and then placed on a slide. A few drops of potassium hydroxide (KOH) are added to the slide to dissolve any non-fungal material, making it easier to see any fungal structures under a microscope. No special preparation is required for the person undergoing the test, but it is important to follow the healthcare provider’s instructions for wound care and infection control to prevent further complications.

Sample Requirements

The sample required for a fungal stain test like KOH preparation on wound secretions is the fluid or discharge from the wound. The healthcare provider will determine the appropriate method for collecting the sample, which may involve cleaning the wound first and collecting the fluid with a swab or syringe.

Additional Notes

It is important to follow the healthcare provider’s instructions for wound care and infection control to prevent further complications. In addition to the fungal stain test like KOH preparation, the healthcare provider may order additional tests, such as a fungal culture or a biopsy, to confirm the diagnosis of a fungal infection. Treatment for fungal infections may involve the use of antifungal medications, wound care, and other supportive therapies, depending on the severity and location of the infection.
