What This Test Measures
The test uses a molecular probe to identify genetic material from common fungal pathogens present in your respiratory secretions. It detects specific DNA sequences linked to fungi such as *Histoplasma*, *Coccidioides*, or others, depending on the clinical suspicion.
Why It’s Ordered
Your healthcare provider may recommend this test if you have symptoms like persistent cough, chest pain, or fever, especially in areas where certain fungal infections are common. It’s also used in patients with weakened immune systems or those at higher risk for fungal infections.
Sample Collection and Preparation
A sterile swab or sample of your respiratory secretions (e.g., sputum or bronchoalveolar lavage fluid) is collected. The sample is then processed in the lab to extract and analyze fungal DNA using a probe-based method.
How Results Are Interpreted
Results are qualitative (positive or negative) for the presence of fungal DNA. A positive result indicates likely fungal infection, while a negative result means no detectable fungal DNA was found in the sample.
Reference range
Adult: 44-147 U/LN/A
No special preparation required. Avoid fatty meals before the test if possible.
Clinical interpretation
How abnormal results are interpreted and what conditions they suggest.
Clinical Significance
Frequently asked questions
A positive test result supports a diagnosis of fungal pneumonia or other respiratory fungal infections, guiding treatment decisions such as antifungal medications. It helps differentiate fungal infections from bacterial or viral causes, ensuring targeted therapy.
The test results are typically available within 2–5 business days, depending on lab processing times.
The sample must be collected properly to ensure accurate results. If you’re taking antifungal medications, inform your provider before testing, as this may affect results.
