What This Test Measures

The fungal panel detects specific fungal markers in your blood or serum using a sensitive immunoassay method. It identifies common fungal pathogens that may be causing an infection, including yeast (e.g., *Candida*) or mold species. Results are qualitative, meaning they indicate whether the test detected fungal presence or not.

Why It’s Done

Your healthcare provider may order this test if you have symptoms of a fungal infection, such as fever, chills, or signs of a systemic illness, especially if you have a weakened immune system, recent surgery, or underlying conditions like diabetes or cancer.

When to Expect Results

Results are typically available within 24 to 48 hours, depending on lab processing times. Your provider will discuss the findings with you during your follow-up visit.

Common Causes of Fungal Infections

Fungal infections can arise from poor immune function, prolonged antibiotic use, or exposure to contaminated environments. Conditions like HIV/AIDS, chemotherapy, or prolonged hospital stays increase risk.

Clinical interpretation

How abnormal results are interpreted and what conditions they suggest.

Positive results confirm a fungal bloodstream infection, guiding treatment decisions such as antifungal medications. Negative results help rule out fungal causes of symptoms, directing care toward other potential infections or conditions.

Short name

Frequently asked questions

What does a positive result mean?
A positive result indicates the presence of fungal organisms in your blood or serum, suggesting a fungal infection. Your doctor will work with you to determine the specific type of fungus and appropriate treatment.
How is this test different from a fungal culture?
This test uses an immunoassay to detect fungal markers directly in your blood or serum, providing results faster than a culture, which grows fungi in a lab over days to weeks. Culture confirms the exact fungus but takes longer.
Can I take anything before this test?
No special preparation is needed. However, inform your provider about any medications, including supplements, as they may affect results.
