Purpose of the Test

The Ear Swab for Fungus Stain/Fungal Smear (KOH) test is conducted to diagnose the presence of a fungal infection in the ear. The test is typically ordered if a patient has symptoms such as ear pain, itching, discharge, or a feeling of fullness in the ear, which may indicate a fungal infection.

When this test is required

This test is typically requested by healthcare providers when a patient presents with symptoms of an ear infection, such as ear pain, discharge, and itching. Patients who have failed to respond to previous treatments for an ear infection may also be recommended for this test.

What the Test Detects

The Ear Swab for Fungus Stain/Fungal Smear (KOH) test is used to detect the presence of fungal infections in the ear. The test is performed by taking a swab of the affected ear and examining it under a microscope to look for fungal cells.

Preparation for the Test

There is no specific preparation needed for this test. However, patients should inform their healthcare provider of any medications they are taking, including over-the-counter drugs and supplements, as some medications may affect the test results.

Sample Requirements

To perform the test, a healthcare provider will take a swab of the affected ear and use a microscope to examine the swab for the presence of fungal cells. The sample is then treated with a potassium hydroxide (KOH) solution to make the fungal cells easier to see under the microscope.

Additional Notes

It’s important to note that a negative result from the test does not necessarily rule out a fungal infection, as the sample collected may not contain enough fungal cells to be detected by the test. In some cases, further testing may be required to confirm the presence of a fungal infection.
