Fasting Required

Purpose of the Test

The test is ordered to detect the presence of fungal infections in the body, especially those caused by opportunistic fungi. It is useful in diagnosing conditions such as fungal pneumonia, fungal meningitis, and other systemic fungal infections.

When this test is required

The test is requested when a healthcare provider suspects a fungal infection in a patient based on their signs and symptoms, medical history, and physical examination. It may also be ordered to monitor the effectiveness of treatment for a known fungal infection.

What the Test Detects

Aspiration fluid for Fungus Stain/Fungal Smear (KOH) test is a microscopic examination that looks for the presence of fungi in a sample of fluid aspirated from a particular site in the body. The test involves staining the sample with potassium hydroxide (KOH) and then examining it under a microscope to identify the presence of fungal elements.

Preparation for the Test

No specific preparation is required for this test. However, the healthcare provider may provide instructions on any dietary or medication restrictions that need to be followed before the test. It is important to inform the healthcare provider about any medications or supplements that the patient may be taking as some of these may interfere with the test results.

Sample Requirements

For this test, a sample of the aspirated fluid is required. The sample is collected through a needle aspiration or a surgical procedure, depending on the location of the suspected infection.

Additional Notes

It is important to note that a negative test result does not necessarily mean that there is no fungal infection present. This is because the presence of fungi may not always be detected in a sample, particularly in cases where the fungal elements are low in concentration or the sample was not collected properly. In some cases, a follow-up test may be needed to confirm the diagnosis. It is also important to follow the healthcare provider’s instructions regarding treatment, even if the test results are negative.
