Why This Test Is Done

Your healthcare provider may order this test if you have symptoms like fever, fatigue, or organ dysfunction that could suggest a fungal infection. It’s also used in patients with weakened immune systems (e.g., from chemotherapy, HIV, or organ transplants) who are at higher risk for fungal infections.

How the Test Works

The test extracts DNA from your blood or plasma and uses a probe to detect specific fungal genetic material. If fungal DNA is present, the probe binds to it, confirming a possible fungal infection.

Sample Collection

A blood sample is drawn from a vein, usually in your arm. The sample is then processed in the lab to analyze for fungal DNA.

What to Expect Before the Test

No special preparation is needed, but inform your provider about any medications or supplements you’re taking, especially those that might affect blood tests.

Clinical interpretation

How abnormal results are interpreted and what conditions they suggest.

Frequently asked questions

What does a positive result mean?
A positive result suggests the presence of fungal DNA in your blood or plasma, which may indicate an infection. Your doctor will work with you to determine the best course of treatment, possibly including antifungal medications.
What if I have a negative result?
A negative result means no fungal DNA was detected in this sample. However, fungal infections can sometimes be hard to detect early. If you continue to have symptoms, your doctor may recommend additional tests or repeat this test.
How soon will I get results?
Results are typically available within 24 to 48 hours, depending on lab processing times. Your healthcare provider will discuss the results with you during your follow-up visit.
