What This Test Measures

The test analyzes genetic material (DNA) from fungi using a specialized probe. This probe binds to unique sequences found in the DNA of certain fungal species, allowing for precise identification.

How the Sample Is Collected

Your healthcare provider will collect a sample, which could be from bodily fluids (like blood, urine, or cerebrospinal fluid) or tissues, depending on the suspected infection site. The sample is then processed to extract fungal DNA for testing.

When This Test Might Be Ordered

Your doctor may recommend this test if you have symptoms like persistent fever, unusual skin lesions, or other signs of a fungal infection, especially if other tests are negative or unclear.

Common Uses and Limitations

This test is useful for confirming fungal infections in cases where traditional cultures or imaging are not definitive. However, it may not detect all fungal species and is best used alongside clinical evaluation and other diagnostic tools.

Clinical interpretation

How abnormal results are interpreted and what conditions they suggest.

Frequently asked questions

Why was this test ordered?
Your doctor may have suspected a fungal infection based on symptoms, medical history, or other diagnostic findings. This test helps confirm the presence of specific fungal species and guides treatment decisions.
What do the results mean?
Positive results indicate the presence of fungal DNA in the sample, suggesting a fungal infection. Negative results mean no detectable fungal DNA was found in this sample. Results should be interpreted by your healthcare provider in the context of your symptoms and medical history.
How long will it take to get results?
Results are typically available within a few days to a week, depending on the laboratory and processing time. Your doctor will discuss the results with you once they are ready.
