Specimen Required

SWAB

Fasting Required

Purpose of the Test

This test is typically performed to detect the presence of fungal organisms in a patient’s body, specifically in a pus sample collected via swab. The test can be ordered when a healthcare provider suspects a patient has a fungal infection.

When this test is required

This test may be requested when a patient presents with symptoms of a fungal infection, such as skin rashes, nail discoloration, or respiratory issues. It may also be ordered for patients with weakened immune systems or other risk factors for fungal infections.

What the Test Detects

The sample collected via pus swab is examined under a microscope after being treated with potassium hydroxide (KOH) solution to determine if any fungal organisms are present.

Preparation for the Test

There is typically no special preparation needed for this test, although it is important to inform the healthcare provider if the patient has recently taken any antibiotics or antifungal medications.

Sample Requirements

The sample required for this test is a pus swab, which is obtained by using a sterile swab to collect a sample of pus from an infected area

Additional Notes

It is important to note that a negative result does not necessarily rule out a fungal infection, as the fungus may not always be present in the collected sample or may not be visible under a microscope. Additional tests or procedures may be necessary for a definitive diagnosis.
