Why Is This Test Done?

Your healthcare provider may order this test if you have symptoms like fever, chills, or unexplained infections. It’s also used in monitoring patients at high risk, such as those with cancer, organ transplants, or severe immune disorders.

What to Expect Before the Test

No special preparation is needed. A healthcare professional will insert a needle into a vein (usually in your arm) to draw blood. You may feel a brief pinch, but it’s usually over quickly. If you’re on antibiotics, let your provider know—it may affect results.

What Happens During the Test?

The blood sample is placed in a special container and sent to a lab. Fungi grow slowly, so results may take days to weeks. If fungi are detected, further testing (like species identification) will follow to guide treatment.

What Are Possible Results?

A positive result means fungi were found in your blood, confirming a fungal infection. A negative result means no fungi were detected in this sample, but infections can sometimes be missed if they’re mild or localized.

Clinical interpretation

How abnormal results are interpreted and what conditions they suggest.

Frequently asked questions

How long does it take to get results?
Results can take several days to weeks, depending on lab processes and fungal growth patterns. Some labs may provide preliminary alerts sooner, but final identification of the organism may take longer.
What does a positive result mean?
A positive result indicates a fungal infection in your blood. Your doctor will work with you to determine the type of fungus and the best treatment plan, which may include antifungal medications.
Can I take antibiotics before the test?
Yes, but inform your healthcare provider immediately. Antibiotics can affect fungal growth in the culture and may influence results. They may adjust your test plan or timing.
